ITEM 1.    BUSINESS

        Unless the context otherwise indicates, all references in this Report to the "Company", "Protection One," "we," "us" or "our" or similar words are to Protection One, Inc., its direct wholly owned subsidiary, Protection One Alarm Monitoring, Inc. ("Protection One Alarm Monitoring") and Protection One Alarm Monitoring's wholly owned subsidiaries.

Westar Energy's Proposed Disposition of Our Stock

        Westar Energy Inc. ("Westar Energy") is a public electric utility and is regulated by the Kansas Corporation Commission ("KCC"). Westar Energy, through its wholly owned subsidiary Westar Industries, Inc., owns approximately 88% of Protection One. On November 8, 2002 the KCC issued an Order, that among many findings and directives, requested Westar Energy consider selling its investment in Protection One.

        Westar Energy subsequently announced that it intends to dispose of its investment in Protection One. We expect to work closely with Westar Energy's management to identify alternatives that are in the best interest of all of our shareholders.

        See further discussion relating to this and additional Orders issued by the KCC and their impact on us in "Significant Business Developments—Kansas Corporation Commission Orders."

Matters to Consider

        We have reported losses for the past several years, working capital has decreased and Westar Energy has announced that it intends to sell its investment in us. Additionally, our current primary financing source is through a credit facility with Westar Energy and credit available under such facility has been limited. We have evaluated these conditions and events in establishing our operating plans. In

3

addition to the plans and strategies noted under "Overview" below, we plan to carefully monitor the level of investment in new customer accounts, continue control of operating expenses, curtail other capital expenditures, if necessary, and continue efforts to extend or replace the credit facility upon its expiration in January 2004. We believe that the funds provided from operations and from the Westar Credit Facility, coupled with receipts under the tax sharing agreement (see "Management's Discussion and Analysis of Financial Condition and Results of Operations"—"Liquidity and Capital Resources") will be sufficient throughout 2003. See "Risk Factors" for a further discussion of these and other important matters.

Overview

        Protection One is a leading provider of property monitoring services, providing electronic monitoring and maintenance of alarm systems to approximately 1.1 million customers as of December 31, 2002. Our revenues are generated primarily from recurring monthly payments for monitoring and maintaining the alarm systems that are installed in our customers' homes and businesses. We provide our services to single family residential, commercial, wholesale and multifamily residential customers. At December 31, 2002, our customer base composition was as follows:

        Our company is divided into two business segments:

        Protection One North America ("North America") generated approximately $252.5 million, or 86.9%, of our revenues in 2002 and is comprised of Protection One Alarm Monitoring, our core alarm monitoring business, and our wholesale monitoring business, which provides alarm monitoring services to independent alarm companies.

        Network Multifamily ("Multifamily") generated approximately $38.1 million, or 13.1%, of our revenues in 2002 and is comprised of our alarm monitoring business servicing apartments, condominiums and other multifamily dwellings.

        Our strategy continues to be to improve returns on invested capital by realizing economies of scale from increasing customer density in the largest urban markets in North America. We plan to accomplish this goal by: (i) retaining our customers by providing superior customer service from our monitoring facilities and our branches; and (ii) using our national presence, strategic alliances such as our alliance with BellSouth Telecommunications, as discussed in "Sales and Marketing" below, and strong local operations to persuade the most desirable residential and commercial prospects to enter into long term agreements with us on terms that permit us to achieve appropriate returns on capital. When we have adequate capital, we would like to resume acquiring alarm companies and portfolios of alarm accounts.

Significant Business Developments

        Kansas Corporation Commission Orders.    On November 8, 2002, the Kansas Corporation Commission issued Order No. 51 which required Westar Energy to initiate a corporate and financial restructuring, reverse specified accounting transactions described in the Order, review, improve and/or develop, where necessary, methods and procedures for allocating costs between utility and non-utility businesses for KCC approval, refrain from any action that would result in its electric businesses

4

subsidizing non-utility businesses, reduce outstanding debt giving priority to reducing utility debt and, pending the corporate and financial restructuring, imposed standstill limitations on Westar Energy's ability to finance non-utility businesses including ours. These standstill protections require that Westar Energy seek KCC approval before it takes actions such as making any loan to, investment in or transfer of cash in excess of $100,000 to us or another non-utility affiliate, entering into any agreement with us or another non-utility affiliate where the value of goods or services exchanged exceeds $100,000, investing, by Westar Energy or Westar Energy's affiliate, of more than $100,000 in an existing or new non-utility business and transferring any non-cash assets or intellectual property to us or another non-utility affiliate. In addition, Westar Energy must charge interest to us and other non-utility affiliates at the incremental cost of our or their debt on outstanding balances of any existing or future inter-affiliate loans, receivables or other cash advances due Westar Energy. The Order also suggested that the sale by Westar Energy of our stock should be explored, along with other alternatives, as a possible source of cash to be used to reduce Westar Energy debt. An additional provision affecting us includes a requirement that we not sell assets having a value of $100,000 or more without prior KCC approval.

        On December 23, 2002, the Kansas Corporation Commission issued Order No. 55 clarifying and modifying the November 8, 2002 Order. One such clarification was that Westar Energy and Westar Industries would be prohibited from making payments to us under our tax sharing agreement with Westar Energy ("Tax Sharing Agreement"—see Note 2(d),"Summary of Significant Accounting Policies—Income Taxes") until certain requirements were met by Westar Energy regarding their debt.

        On January 10, 2003, we filed a petition with the KCC seeking reconsideration of certain aspects of Order No. 55. Specifically, we requested that the Commission reconsider and revise Order No. 55 so that it clearly does not interfere with our contractual arrangements with Westar Energy and Westar Industries, including, but not limited to the Tax Sharing Agreement and the Westar Credit Facility.

        On February 11, 2003, the parties to the KCC proceeding filed a Limited Stipulation and Agreement, which sought the KCC's approval for us to sell all of our Westar Energy stock to Westar Energy. The KCC approved the Limited Stipulation and Agreement on February 14, 2003. We sold all of our Westar Energy stock to Westar Energy on February 14, 2003 for $11.6 million.

        On February 25, 2003, we entered into a Partial Stipulation and Agreement (the Reconsideration Agreement) with the Staff of the KCC, Westar Energy, Westar Industries and an intervenor. The Reconsideration Agreement requested that the KCC issue an order granting limited reconsideration and clarification to its order issued December 23, 2002. The Reconsideration Agreement also requested that the KCC authorize Westar Energy and Westar Industries to perform their respective obligations to us under the Tax Sharing Agreement and the Westar Credit Facility. Additionally, the Reconsideration Agreement provided that, among other things; (a) the maximum borrowing capacity under the Westar Credit Facility will be reduced to $228.4 million and the maturity date may be extended one year to January 5, 2005; (b) Westar Energy may provide funds to Westar Industries to the extent necessary to perform its obligations to us under the Westar Credit Facility; (c) Westar Energy will reimburse us approximately $4.4 million for expenses incurred in connection with services provided by Protection One Data Services and AV One, Inc. to Westar Energy and Westar Industries, and for the sale of AV One, Inc. to Westar Energy; and (d) the Management Services Agreement (see Note 6, "Related Party Transactions") between us and Westar Industries is cancelled.

        On March 11, 2003, the KCC issued Order No. 65 conditionally approving the Reconsideration Agreement. The KCC imposed the following on the terms of the Reconsideration Agreement: (a) the Westar Credit Facility must be paid off upon the sale of all or a majority of our common stock held by Westar Industries, and this pay-off must be a condition of any sale by Westar Industries of our stock; (b) Westar Energy must provide advance notice to the KCC if the payment due from Westar Energy for the 2002 tax year under the Tax Sharing Agreement exceeds approximately $20 million; (c) we must receive KCC approval prior to selling any assets exceeding $100,000 and Westar Energy and Westar

5

Industries must receive KCC approval prior to selling their investment in our stock; and (d) we must waive potential claims against Westar Energy and Westar Industries relating to certain inter-company agreements. In addition, the KCC reserved the right to impose a deadline for the sale by Westar Industries of its investment in our stock. Westar Energy is precluded from extending any credit to us except for borrowings we may make under the Westar Credit Facility.

        In addition, on March 19, 2003, we submitted two letters to the KCC in response to KCC Order No. 65, one of which was addressed to the KCC and the other of which was addressed to Westar Energy. As described in the letters, we agreed to (i) release Westar Energy from certain claims relating to Protection One Data Services, Inc ("PODS"), AV One, Inc. and the Management Services Agreement and (ii) accept the conditions set forth in Order No. 65 relating to matters other than PODS, AV One, Inc. and the Management Services Agreement. We do not intend to seek reconsideration of Order No. 65.

        Reference is made to Westar Energy's Annual Report on Form 10-K for the year ended December 31, 2002 and its previous Form 10-K and Forms 10-Q filed with the Securities and Exchange Commission (File No. 1-3523) for further information on these orders and proceedings, which may adversely impact us. Reference is also made to the Kansas Corporation Commission Orders dated November 8, 2002, December 23, 2002, February 10, 2003 and March 11, 2003 and the Reconsideration Agreement filed as Exhibits to this Annual Report on Form 10-K and incorporated herein by reference.

        Attrition and Customer Creation.    In 2002, we had a net loss of 59,625 customers in our customer base. Our North America segment had a net loss of 62,988 customers while our Multifamily segment had a net increase of 3,363 customers. This decline resulted from attrition, the decision to add new customers at reasonable costs through our internal sales force and to focus on operational efficiencies, and the disposition of certain accounts. Our customer acquisition strategy for our North America segment relies primarily on our internal sales force, which generated 45,642 accounts in 2002 compared to 41,856 accounts in 2001, and our marketing alliance with BellSouth Telecommunications, Inc. See "Sales and Marketing," "Attrition."

        Operational Efficiencies.    In January 2002, we completed the installation of our common technology platform for customer service, monitoring, billing and collection functions in our Wichita, Kansas and Portland, Maine facilities. See "Centralized Monitoring, Common Technology Platform and Customer Service."

        Impairment Charge.    In the first quarter of 2002, we recorded an impairment charge to write-down goodwill and customer accounts to their estimated fair values. The amount of this charge net of tax was approximately $765.2 million, of which approximately $543.6 million was related to goodwill and approximately $221.6 million was related to customer accounts. In addition, we recorded a $90.7 million impairment charge, net of $13.3 million tax, in the fourth quarter of 2002 to reflect the impairment of all remaining goodwill of our North America segment. We still have $41.8 million of goodwill at December 31, 2002 associated with our Multifamily reporting unit. For further information, see "Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations-Impairment Charges Pursuant to New Accounting Rules" and Note 14 of the "Notes to Consolidated Financial Statements."

        Discontinued Operations.    During the second quarter of 2002 we entered into negotiations for the sale of our Canadian business which was included in our North American segment. The sale was consummated on July 9, 2002. We recorded a pretax impairment loss of approximately $2.0 million and an after tax loss of approximately $1.3 million in the second quarter of 2002 as a result of the sale.

        The net operating losses of the Canadian operations are included in the consolidated statements of operations under "discontinued operations." The net operating loss for the year ended December 31, 2002 of $1.6 million includes an impairment loss on customer accounts of approximately $1.9 million.

6

An impairment charge of $2.3 million relating to the Canadian operations' goodwill is reflected in the consolidated statement of operations as a cumulative effect of accounting change on discontinued operations. Revenues from these operations were $4.2 million for the six months ended June 30, 2002, compared to $4.1 million for the six months ended June 30, 2001 and $4.2 million compared to $8.2 million for the year ended December 31, 2002 and 2001 respectively.

        The major classes of assets and liabilities of the Canadian operations were as follows (in thousands):

        In June 2002, we formed a wholly owned subsidiary named Protection One Data Services, Inc. and on July 1, 2002 transferred to it approximately 42 of our Information Technology employees. Effective July 1, 2002, PODS entered into an outsourcing agreement with Westar Energy pursuant to which PODS provided Westar Energy information technology services. As a condition of the agreement, PODS offered employment to approximately 100 Westar Energy Information Technology employees. Operation of the subsidiary and the supply of such services to Westar Energy was discontinued as of December 31, 2002. The approximately 142 Information Technology employees that had accepted employment with PODS returned to their respective companies as of the end of the year. The net income of PODS operations of approximately $0.3 million is included in the consolidated statements of operations under "discontinued operations." Revenues from these operations totaled $11.2 million for the six months of their operation ending December 31, 2002. PODS had $1.1 million in receivables from Westar Energy and $0.4 million in accounts payable as of December 31, 2002.

Operations

        Our operations consist principally of installing, servicing and monitoring premise intrusion and fire alarms.

Centralized Monitoring, Common Technology Platform and Customer Service

        Customer Security Alarm Systems.    Security alarm systems include many different types of devices installed at customers' premises designed to detect or react to various occurrences or conditions, such as intrusion or the presence of fire or smoke. In general, systems for multifamily and residential applications tend to be smaller in size than those used by commercial customers, and also tend to generate a lower level of alarm signals than in commercial applications. These devices are connected to a computerized control panel that communicates through the phone lines to a monitoring facility. In most systems, control panels can identify the nature of the alarm and the areas within a building where the sensor was activated, and can transmit that information to a central monitoring station.

        Customer Contracts.    Our existing alarm monitoring customer contracts generally have initial terms ranging from two to ten years in duration, and, in most states, provide for automatic renewals for a fixed period (typically one year) unless we or the customer elect to cancel the contract at the end of its term. Since 2002, most new single family residential customers have been entering into contracts with

7

an initial term of three years and, for most new commercial customers, the initial term is five years. Typically, customers sign alarm monitoring contracts that include a bundled monthly charge for monitoring and extended service protection. Extended service protection covers the normal costs of repair of the security system after the expiration of the security system's initial warranty period. Customers may elect to sign an alarm monitoring contract that excludes extended service protection. A significant percentage of new residential and commercial customers are also electing to include line security based on cellular technology in their service bundle.

        Monitoring Facilities.    We provide monitoring services to our customer base from four monitoring facilities. The table below provides additional detail about our monitoring centers:

        Our monitoring facilities operate 24 hours per day, seven days a week, including all holidays. Each monitoring facility incorporates the use of communications and computer systems that route incoming alarm signals and telephone calls to operators. Each operator within a monitoring facility monitors a computer screen that presents information concerning the nature of the alarm signal, the customer whose alarm has been activated, and the premises on which such alarm is located. Other non-emergency administrative signals are generated by low battery status, arming and disarming of the alarm monitoring system, and test signals, and are processed automatically by computer. Depending upon the type of service for which the customer has contracted, monitoring facility personnel respond to alarms by relaying information to the local fire or police departments, notifying the subscriber, or taking other appropriate action, such as dispatching alarm response personnel to the customer's premises where this service is available.

        All of our primary monitoring facilities are listed by Underwriters Laboratories, Inc. ("UL") as protective signaling services stations. UL specifications for monitoring facilities include building integrity, back-up computer and power systems, staffing and standard operating procedures. In many jurisdictions, applicable law requires that security alarms for certain buildings be monitored by UL listed facilities. In addition, such listing is required by certain commercial customers' insurance companies as a condition to insurance coverage.

        Common Technology Platform.    In recognition of the strategic importance of serving all our customers on a common database running on an industry standard monitoring automation application, in 2000 we adopted MAS®, from Monitored Automation Systems, of Irvine, California, as the technology platform for our monitoring facilities. MAS® combines customer service, monitoring, billing and collection functions into a single system and is used, to varying extents, by other large companies in the security monitoring industry including ADT Security Services and Brink's Home Security (see Competition, below).

        In 2001, we completed the consolidation of several monitoring facilities into our Wichita monitoring facility and completed Wichita's conversion to MAS®. With the conversion to MAS® of the Portland, Maine facility in January 2002, we serve approximately 98.5% of our North America residential and commercial customer base by utilizing one common database. Our new commercial customers, whose requirements often exceed those of typical residential customers, are being monitored in our Portland, Maine facility. We also completed the installation of a new financial system which we began using in January 2001 that can be accessed in all of our locations.

8

        Wholesale Monitoring.    Through our monitoring facilities in Longwood and Wichita, we provide wholesale monitoring services to independent alarm companies. Under the typical arrangement, alarm companies subcontract monitoring services to us, primarily because they cannot cost-effectively provide their own monitoring service. We may also provide billing and other services. These independent alarm companies retain ownership of monitoring contracts and are responsible for every other aspect of the relationship with customers, including field repair service.

        Customer Care Services.    Customer care personnel answer non-emergency telephone calls typically regarding service, billing and alarm activation issues. Until late 2001, all customer care personnel were located exclusively in our monitoring facilities. During the last quarter of 2001, we began shifting some business-hours customer care functions to our branches, including responding to routine billing and service inquiries. In 2002, we completed the shifting of most business-hours customer care functions to our branches. During business hours, monitoring facility personnel receive inbound customer calls forwarded from branches when the latter are unable to answer within a specified number of rings. After-hours, all customer calls are forwarded to the monitoring facilities.

        Customer care personnel in our branches and in our monitoring facilities at help desks assist customers in understanding and resolving minor service and operating issues related to security systems. Branch personnel schedule technician appointments. We also operate a dedicated telesales center in Wichita to address questions that customers or potential customers have about our services, as well as to perform outbound sales and marketing activities.

        Enhanced Services.    As a means of increasing revenues and enhancing customer satisfaction, we offer customers an array of enhanced security services, including extended service protection, supervised monitoring services, and telephone line security based on wireless technology. These services position us as a full service provider and give our sales representatives more features to sell in their solicitation of new customers. Enhanced services include:

•

Extended Service Protection, which covers the normal costs of repairing the system during regular business hours, after the expiration of the initial warranty period.



•

Supervised Monitoring Service, which allows the alarm system to send various types of signals containing information on the use of the system, such as which users armed or disarmed the system and at what time of the day. This information is supplied to customers for use in connection with the management of their households or businesses. Supervised monitoring service can also include a daily automatic test feature.



•

Wireless Back-Up, which permits the alarm system to send signals over a cellular telephone or dedicated radio system in the event that regular telephone service is interrupted.

Branch Operations

        We maintain approximately sixty service branches in North America from which we provide field repair, customer care, alarm response and sales services, and seven satellite locations from which we provide field repair services. In 2002, we completed the shifting of most business-hours customer care functions to our branches by expanding the range of functions provided at our branches to include billing set-up and some collection functions. Our nationwide network of branches operates in some of the largest cities in the United States and plays a critical role in enhancing customer satisfaction, reducing customer loss and building brand awareness. Repair services generate revenues primarily through billable field service calls and recurring payments under our extended service protection program. By focusing growth in targeted areas we hope to increase the density of our customer base which will permit more effective scheduling and routing of field service technicians and will create economies of scale.

9

Sales and Marketing

        Our current customer acquisition strategy for our North America segment relies primarily on internally generated sales. In June 2001, we notified most of our remaining domestic dealers that we were terminating our dealer arrangement with them and therefore would not be extending or renewing their contracts. The number of accounts being purchased through our dealer program decreased to 1,135 accounts in 2002 from 7,501 accounts in 2001.

        Our internal sales program for our North America segment was started in February 2000 on a commission only basis with a goal of creating accounts at a cost lower than our external programs. In 2001, we revised and enhanced our internal sales program, and in 2002, enhanced the benefits package for our sales force. This program utilizes our existing branch infrastructure in approximately sixty markets. The internal sales program for our North America segment generated 45,642 accounts and 41,856 accounts in 2002 and 2001, respectively.

        We are a partner in a marketing alliance with BellSouth Telecommunications, Inc. ("BellSouth") to offer monitored security services to the residential, single family market and to small businesses in seventeen of the larger metropolitan markets in the nine-state BellSouth region. The term of the marketing alliance will renew for a two-year period on December 31, 2003, unless terminated by either party. Under this agreement, we operate as "BellSouth Security Systems from Protection One" from our branches in the nine-state BellSouth region. BellSouth provides us with leads of new owners of single family residences in its territory and of transfers of existing BellSouth customers within its territory. We follow up on the leads and attempt to persuade them to become customers of our monitored security services. We also market directly to small businesses. We pay BellSouth an upfront royalty for each new contract and a recurring royalty based on a percentage of recurring charges. Approximately one-fourth of our new accounts created in 2002 were produced from this arrangement. Termination of this agreement could have an adverse affect on our ability to generate new customers in this territory.

        Sales professionals are responsible for identifying new prospects and closing new sales of monitoring systems and services. The sales force also generates revenue from selling equipment upgrades and add-ons to existing customers and by competing for those customers who are terminating their relationships with our competitors.

        We operate a dedicated telesales center ("Telesales") in Wichita from which we respond to questions that customers or potential customers have about our services, support the alliance with BellSouth, and provide quality control follow-up calls to customers for whom we recently provided installation or maintenance services.

        Our Multifamily segment utilizes a salaried and commissioned sales force to produce new accounts. Multifamily markets its services and products primarily to developers, owners and managers of apartment complexes and other multifamily dwellings. Multifamily sales and marketing activities consist of national and regional advertising, nationwide professional field sales efforts, prospective acquisition marketing efforts and professional industry-related association affiliation. Services are sold directly to the property owner, and payment is based on a monthly price on a per-unit basis. Ongoing service for the duration of the lease includes equipment, maintenance, 24-hour monitoring from our central monitoring station, customer service and individual market support. Property owner contracts generally have initial terms ranging from five to ten years in duration, and provide for automatic renewal for a fixed period (typically five years) unless Multifamily or the subscriber elects to cancel the contract at the end of its term.

        We continually evaluate our customer creation and marketing strategy, including evaluating each respective channel for economic returns, volume and other factors and may shift our strategy or focus, including the elimination of a particular channel.

10

Attrition

        Subscriber attrition has a direct impact on our results of operations since it affects our revenues, amortization expense and cash flow. We define attrition as a ratio, the numerator of which is the gross number of lost customer accounts for a given period, net of the adjustments described below, and the denominator of which is the average number of accounts for a given period. In some instances, we use estimates to derive attrition data. We make adjustments to lost accounts primarily for the net change, either positive or negative, in our wholesale base and for accounts which are covered under a purchase price holdback and are "put" back to the seller. We reduce the gross accounts lost during a period by the amount of the guarantee provided for in the purchase agreements with sellers. In some cases, the amount of the purchase holdback may be less than actual attrition experience. Adjustments to lost accounts for purchase holdbacks have been decreasing because we are purchasing fewer accounts in the types of transactions that create holdbacks. We do not reduce the gross accounts lost during a period by "move in" accounts, which are accounts where a new customer moves into the premises equipped with the Company's security system and vacated by a prior customer, or "competitive takeover" accounts, which are accounts where the owner of a premise monitored by a competitor requests that we provide monitoring services.

        Our actual attrition experience shows that the relationship period with any individual customer can vary significantly. Customers' service can be discontinued for a variety of reasons, including relocation, non-payment, customers' perception of value and competition. A portion of the acquired customer base can be expected to discontinue service every year. Any significant change in the pattern of our historical attrition experience would have a material effect on our results of operations.

        We monitor attrition each quarter based on an annualized and trailing twelve-month basis. This method utilizes each segment's average customer account base for the applicable period in measuring attrition. Therefore, in periods of customer account growth, customer attrition may be understated and in periods of customer account decline, customer attrition may be overstated.

        Customer attrition by business segment for the years ended December 31, 2002, 2001 and 2000 is summarized below:

(a)

Does not include the Europe segment which we sold in February 2000 or the Canguard operations which we sold in July 2002.

        Attrition decreased in our North America Segment in 2002 compared to 2001 for a variety of reasons including:

•

An aggressive campaign, named "Save Our Subscribers" designed to retain our existing customers;



•

an emphasis on customer service and attrition reduction by branch and monitoring center personnel; and



•

legal action taken against competitors who illegally solicit our customers.

11

Competition

        The security alarm industry is highly competitive. In North America, there are only four alarm companies that offer services across the United States with the remainder being either large regional or small, privately held alarm companies. Based on total annual revenues in 2001, we believe the top four alarm companies in North America are:

•

ADT Security Services ("ADT"), a subsidiary of Tyco International, Inc.



•

Protection One, Inc.



•

Brink's Home Security Inc., a subsidiary of The Pittston Company



•

Honeywell Security, a division of Honeywell, Inc.

        Competition in the security alarm industry is based primarily on market visibility, price, reputation for quality of services and systems, services offered, and the ability to identify and to solicit prospective customers as they move into homes and businesses. We believe that we compete effectively with other national, regional and local security alarm companies due to our ability to offer integrated alarm system installation, monitoring, repair and enhanced services, our reputation for reliable equipment and services, our affinity alliance with BellSouth, and our prominent presence in the areas surrounding our branch offices.

Intellectual Property

        We own trademarks related to the name and logo for Protection One and Network Multifamily Security as well as a variety of trade and service marks related to individual services we provide. While we believe our trademarks and service marks and proprietary information are important to our business, other than the trademarks we own in our name and logo, we do not believe our inability to use any one of them would have a material adverse effect on our business as a whole.

Regulatory Matters

        A number of local governmental authorities have adopted or are considering various measures aimed at reducing the number of false alarms (see "Risk Factors"). Such measures include:

•

permitting of individual alarm systems and the revocation of such permits following a specified number of false alarms;



•

imposing fines on alarm customers for false alarms;



•

imposing limitations on the number of times the police will respond to alarms at a particular location after a specified number of false alarms;



•

requiring further verification of an alarm signal before the police will respond; and



•

subjecting alarm monitoring companies to fines or penalties for transmitting false alarms.

        Our operations are subject to a variety of other laws, regulations and licensing requirements of federal, state, and local authorities. In certain jurisdictions, we are required to obtain licenses or permits, to comply with standards governing employee selection and training, and to meet certain standards in the conduct of our business.

        The alarm industry is also subject to requirements imposed by various insurance, approval, listing, and standards organizations. Depending upon the type of customer served, the type of security service provided, and the requirements of the applicable local governmental jurisdiction, adherence to the requirements and standards of such organizations is mandatory in some instances and voluntary in others.

12

        Our advertising and sales practices are regulated in the United States by both the Federal Trade Commission and state consumer protection laws. In addition, certain administrative requirements and laws of the jurisdictions in which we operate also regulate such practices. Such laws and regulations include restrictions on the manner in which we promote the sale of our security alarm systems and the obligation to provide purchasers of our alarm systems with rescission rights.

        Our alarm monitoring business utilizes wireline and wireless telephone lines and radio frequencies to transmit alarm signals. The cost of telephone lines, and the type of equipment which may be used in telephone line transmission, are currently regulated by both federal and state governments. The Federal Communications Commission and state public utilities commissions regulate the operation and utilization of radio frequencies.

Risk Management

        The nature of the services provided by Protection One potentially exposes us to greater risks of liability for employee acts or omissions, or system failure, than may be inherent in other businesses. Substantially all of our alarm monitoring agreements, and other agreements, pursuant to which we sell our products and services contain provisions limiting liability to customers in an attempt to reduce this risk.

        We carry insurance of various types, including general liability and errors and omissions insurance in amounts management considers adequate and customary for our industry and business. Our loss experience, and the loss experiences at other security service companies, may affect the availability and cost of such insurance. Some of our insurance policies, and the laws of some states, may limit or prohibit insurance coverage for punitive or certain other types of damages, or liability arising from gross negligence.

Employees

        At December 31, 2002, we had approximately 2,800 full-time employees. Our workforce is not unionized.

Access to Company Information

        We electronically file our annual report on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K with the Securities and Exchange Commission (SEC).

RISK FACTORS

Cautionary Statements Regarding Future Results of Operations

        You should read the following risk factors in conjunction with discussions of factors discussed elsewhere in this and other of our filings with the SEC. These cautionary statements are intended to highlight certain factors that may affect our financial condition and results of operations and are not meant to be an exhaustive discussion of risks that apply to public companies with broad operations, such as us.

13

Introduction

        We have reported losses for the past several years, working capital has decreased and Westar Energy has announced that it intends to sell its investment in us. Additionally, our current primary financing source is through a credit facility with Westar Energy and credit available under such facility has been limited. We have evaluated these conditions and events in establishing our operating plans. In addition to the plans and strategies noted below, we plan to carefully monitor the level of investment in new customer accounts, continue control of operating expenses, curtail other capital expenditures, if necessary, and continue efforts to extend or replace the credit facility upon its expiration in January 2004. We believe that the funds provided from operations and from the Westar Credit Facility, coupled with receipts under the tax sharing agreement (see "Management's Discussion and Analysis of Financial Condition and Results of Operations"—"Liquidity and Capital Resources") will be sufficient throughout 2003. See further discussion of these and other important matters below.

We have had a history of losses which are likely to continue.

        We incurred net losses of $880.9 million in 2002, $86.0 million in 2001 and $57.2 million in 2000. These losses reflect, among other factors:

•

our customer base and revenues have declined since 1999;



•

substantial charges incurred by us for amortization of purchased customer accounts and an impairment charge to purchased accounts in 2002;



•

amortization of goodwill in 2000 and 2001 and impairment charges for 2002;



•

interest incurred on indebtedness;



•

other charges required to manage operations;



•

costs associated with the integration of the acquisitions we have made; and



•

expansion of our internal sales and installation efforts.

        We will continue to incur substantial interest expense unless we significantly reduce our debt which is unlikely given our expected cash flow. We do not expect to attain profitable operations in the foreseeable future.

Westar Industries is our principal stockholder and can exercise a controlling influence over us.

        Westar Industries owned approximately 88% of the outstanding common stock of Protection One as of December 31, 2002. As long as Westar Industries continues to beneficially own in excess of 50% of the shares of Protection One common stock outstanding, Westar Industries will be able to direct the election of all of our directors and exercise a controlling influence over our business and affairs, including any determinations with respect to mergers or other business combinations involving us, appointment of our officers, our acquisition or disposition of material assets and our incurrence of indebtedness. Similarly, Westar Industries will continue to have the power to determine matters submitted to a vote of our stockholders without the consent of other stockholders, to prevent or cause a change in control of Protection One and to take other actions that might be favorable to Westar Energy and Westar Industries, whether or not these actions would be favorable to us or our stockholders generally. In addition, Westar Industries is also our sole lender under the Westar Credit Facility as discussed below.

14

Westar Energy's announcement that it intends to sell its investment in us may cause us to focus on short-term business alternatives instead of long-term business alternatives.

        Westar Energy has announced that it intends to sell its investment in Protection One. This may cause Westar Energy, as our controlling stockholder, to focus on business strategies that are in the short-term best interest of the company and our stockholders but not necessarily in the long-term best interest of the company and our stockholders. This could mean, for example, that a substantial amount of management time may be spent pursuing a sale strategy instead of building the company, its business and its assets for the long-term. As a result, during the sale process, we may experience difficulty developing new long-term customers and maintaining relationships with companies with which we do business who may feel uncertain about the future ownership, management and direction of the company. In addition, while we have recently entered into new employment contracts with our key employees to provide incentives for such employees to remain with the company through a sales process, we may be unable to retain the services of some of our key employees who may also feel uncertain about the future ownership, management and direction of the company.

Westar Energy is engaged in regulatory proceedings which could adversely affect us.

        The Kansas Corporation Commission has issued orders that may directly impact transactions between us, Westar Industries and Westar Energy. See further discussion relating to these orders issued by the KCC and their impact on us in "Significant Business Developments—Kansas Corporation Commission Orders" (some of which orders are filed as exhibits hereto and are incorporated by reference herein). Reference is also made to the Westar Energy Forms 10-K (including its Form 10-K for the year ended December 31, 2002), Forms 10-Q and Forms 8-K filed with the Securities and Exchange Commission (File No. 1-3523) for further information on these orders and proceedings, which may adversely impact us.

We obtain administrative services from and share information technology systems with Westar Energy through our shared services agreement which, if terminated, may result in increased costs.

        Westar Energy provides us certain administrative services pursuant to a services agreement (the "Administrative Services Agreement"—see Note 6, "Related Party Transactions") including accounting, tax, audit, human resources, legal, purchasing and facilities services. Westar Energy and we have entered into an amended service agreement that stipulates if Westar Energy sells its interest in us, Westar Energy and we will negotiate in good faith to agree upon the terms and conditions for continuation of the services during an agreed-upon transition period. This agreement would have to be approved by the KCC. If the services agreement is terminated, our cost of obtaining such services from either a third party or by hiring sufficient staff to perform those services internally may increase and we may incur costs to procure and to develop replacement information technology systems.

We have deferred tax assets we may not utilize.

        Westar Energy makes payments to us for current tax benefits utilized by Westar Energy in its consolidated tax return pursuant to a tax sharing agreement, which is an important source of liquidity for us. If Westar Energy completes its intended disposition of its investment in us, our net deferred tax assets, which were $294.9 million at December 31, 2002, might not be realizable and we might not be in a position to record a tax benefit for losses incurred. We would be required to record a non-cash charge against income for the portion of our net deferred tax assets we determine not to be realizable. This charge could be material and could have a material adverse effect on our business, financial condition and results of operations. The amount of our deferred taxes increased by approximately $190.7 million upon our recording of an impairment charge in the first quarter of 2002 and $13.3 million in the last quarter of 2002 as discussed below. In addition, as a result of a sale, we would no longer receive payments from Westar Energy for current tax benefits utilized by Westar Energy. In

15

2002 and 2001, we received aggregate payments from Westar Energy of $1.7 million and $19.1 million, respectively. The loss of these payments would have a material adverse effect on our cash flow.

We will need to extend or refinance our Westar Credit Facility to maintain liquidity.

        Our ability to refinance our Westar Credit Facility and satisfy any payment obligations will depend, in large part, on our performance, which will ultimately be affected by general economic and business factors, many of which will be outside management's control. We believe that our cash flow from operations, tax payments from Westar Energy, borrowings under the Westar Credit Facility and asset sales (we may not sell assets in excess of $100,000 without KCC approval) will be enough to meet our expenses and interest obligations through January 5, 2004. Our ability to operate beyond that date will depend on the renewal or refinancing of the Westar Credit Facility. The KCC has authorized Westar Energy to extend its Westar Credit Facility to January 5, 2005, and has stated that the Westar Credit Facility must be terminated upon any sale by Westar Energy of its investment in us. Any extension beyond January 5, 2005, would require further approval of the KCC. Westar Energy is prohibited from extending any credit to us except under the Westar Credit Facility. The KCC has authorized the extension of the Westar Credit Facility to January 5, 2005 and Westar Energy has indicated that it is willing to extend the January 5, 2004 maturity date of the facility. Westar Energy has also indicated it may require some form of collateral, either upon the execution of an extension or upon the occurrence of events to be determined, to secure all or a portion of our obligation under the Westar Credit Facility. The indentures governing our 13⁵/8% senior subordinated discount notes and 6³/4% convertible senior subordinated notes prohibit us from securing any of our senior debt unless all other senior debt is secured; and our 7³/8% senior notes prohibit us from securing senior debt without providing security for the 7³/8% senior notes, subject to certain permitted carve outs as defined in the indenture. We are currently in discussions with Westar Energy regarding the terms of an extension of the Westar Credit Facility. Westar Energy has provided assurance that it presently intends to renew the Westar Credit Facility through January 5, 2005 should such renewal be necessary to provide us continued liquidity at January 5, 2004 when the facility is currently scheduled to terminate. In the event our Westar Credit Facility is not extended on its present terms and we are required to seek such financing from unaffiliated third parties, we may not be able to do so on terms as economically favorable as those under our present Westar Credit Facility or at all.

        We would face significant liquidity issues if Westar Industries were unable to fund its obligations under the Westar Credit Facility. We were unsuccessful in refinancing our Westar Credit Facility with unaffiliated third parties on satisfactory terms in 2000 and 2001. If payment obligations cannot be satisfied, we will be forced to find alternative sources of funds by selling assets, restructuring, refinancing debt or seeking additional equity capital. There can be no assurance that any of these alternative sources would be available on satisfactory terms or at all.

Our debt agreements impose operational restrictions on us.

        The indentures governing our public indebtedness require us to satisfy certain financial covenants in order to borrow additional funds. The most restrictive of these covenants are set forth below:

•

Total debt to annualized EBITDA for the most recent quarter must be less than 6.0 to 1.0;



•

EBITDA to interest expense for the most recent quarter must be greater than 2.25 to 1.0; and



•

Senior debt to annualized EBITDA for the most recent quarter must be less than 4.0 to 1.0.

        In each case, the ratio reflects the impact of acquisitions and other capital investments for the entire period covered by the calculation. These debt instruments contain restrictions based on "EBITDA". The definition of EBITDA varies among the various indentures. EBITDA is generally derived by adding to income (loss) before income taxes, the sum of interest expense and depreciation

16

and amortization expense. However, under the varying definitions of the indentures, additional adjustments are required. Below are the ratios for the quarter ended December 31, 2002:

•

Total debt to annualized EBITDA of 4.0 to 1.0;



•

EBITDA to interest expense of 3.1 to 1.0; and



•

Senior debt to annualized EBITDA of 2.9 to 1.0.

        The indentures contain other covenants that impose operational restrictions on us which are not as burdensome to us as those listed above and none are based on credit ratings. A violation of these restrictions would result in an event of default which would allow the lenders to declare all amounts outstanding immediately due and payable.

We have a substantial amount of debt, which could constrain our growth.

        We have, and will likely continue to have, a large amount of consolidated indebtedness. The terms of various indentures and credit agreements discussed above governing our indebtedness limit our ability to incur additional indebtedness that we might need in the future in order to fund creation of subscriber accounts.

        Additionally, please be aware that:

•

As of December 31, 2002, we had outstanding total indebtedness of $558.0 million, of which $547.8 million was long-term indebtedness;



•

as of December 31, 2002, we had $215.5 million of debt outstanding under our Westar Credit Facility bearing interest at a weighted average floating interest rate before fees of 5.2%. As of April 3, 2003 we had $215.5 million of debt outstanding under our $228.4 million Westar Credit Facility bearing interest at a weighted average floating interest rate before fees of 5.1%; and



•

our Convertible Senior Subordinated Notes, which represent $9.7 million of our short-term indebtedness, mature in September 2003.

        Our present high level of indebtedness could have negative consequences on, without limitation:

•

our ability to obtain additional financing in the future for working capital, acquisitions or creation of subscriber accounts, capital expenditures, general corporate purposes or other purposes;



•

our ability to withstand a downturn in our business or the economy generally; and



•

our ability to compete against other less leveraged companies.

        As discussed in "Significant Business Developments," our Westar Credit Facility must be paid off upon a sale by Westar Energy of its investment in us. Furthermore, the indentures governing our debt securities require that we offer to repurchase the securities in certain circumstances following a change of control:

•

The Senior Subordinated Discount Notes (13⁵/8%) and Convertible Notes (6³/4%) require us to make a repurchase offer at approximately 101% of principal amount, plus interest in the event of a change in control; and



•

the Senior Notes (7³/8%) and Senior Subordinated Notes (8¹/8%) require us to make a repurchase offer at 101% of principal amount, plus interest in the event of a change in control coupled with two ratings downgrades that occur after the date the Company announces an intent to pursue a transaction that results in a change of control.

17

        As of December 31, 2002, we had $29.9 million principal amount of the Senior Subordinated Discount notes, $9.7 million principal amount of the Convertible Notes, $190.9 million principal amount of the Senior Notes and $110.3 million principal amount of the Senior Subordinated Notes.

        Should a change in control occur in connection with Westar Energy's disposition of its investment in our common stock, we anticipate that a purchaser of Westar Energy's interest in us would negotiate the amendment of the terms of our outstanding debt requiring its repurchase, or assist us in finding sufficient sources of funds to meet our repurchase obligations. We also anticipate that a purchaser would assist us in arranging for new credit facilities or provide us needed credit. However, we can give no assurance that any such arrangements will or could be made or any needed funds otherwise be provided.

We recorded impairment charges in 2002 and additional charges may be recorded in the future.

        In the first quarter of 2002, we recorded an impairment charge to write-down goodwill and customer accounts to their estimated fair values. The amount of this charge net of tax was approximately $765.2 million, of which approximately $543.6 million was related to goodwill and approximately $221.6 million was related to customer accounts. In addition, we recorded a $90.7 million impairment charge, net of $13.3 million tax, in the fourth quarter of 2002 to reflect the impairment of all remaining goodwill of our North America segment. For further information on the impairment charge, see Note 14 of the "Notes to Consolidated Financial Statements." We still have $41.8 million of goodwill associated with our Multifamily segment and $312.8 million in customer accounts recorded on our December 31, 2002 balance sheet. The remaining amount of goodwill will be required to be tested annually for impairment. We established July 1 as our annual impairment testing date. We completed this testing during the third quarter of 2002 and determined that no additional impairment was required as of July 1, 2002. Goodwill is required to be tested upon certain triggering events, which include recurring operating losses, adverse business conditions, adverse regulatory rulings, and other matters that negatively impact value. After regulatory actions (see Note 6, "Related Party Transactions"), including Kansas Corporation Commission Order No. 55, which prompted our parent company to advise us that it intended to dispose of its investment in us, we retained the independent appraisal firm to perform an additional valuation of our reporting units, so we could perform an impairment test as of December 31, 2002. The order limited the amount of capital the parent could provide to us and increased our risk profile. Therefore, we reevaluated our forecast, reducing the amount of capital invested over our forecast horizon and lowered our base monthly recurring revenue to incorporate actual 2002 results, which resulted in a lower valuation than our July 1, 2002 valuation. As a result, we recorded an additional impairment charge in the fourth quarter as discussed above. If we fail future impairment tests for either goodwill or customer accounts, we will be required to recognize additional impairment charges on these assets in the future. Any such impairment charges could be material.

The competitive market for the acquisition and creation of accounts may affect our future profitability.

        Prior to 2000, we grew very rapidly by acquiring portfolios of alarm monitoring accounts through acquisitions and dealer purchases. Our current strategy is to reduce the cost of acquiring new accounts by utilizing other customer account acquisition channels such as our internal sales force augmented by traditional marketing support. We would like to resume acquiring alarm account portfolios or alarm companies on a limited basis at some time during 2004 if we have adequate capital. We compete with major companies, some of which have greater financial resources than we do, or may be willing to offer higher prices than we might be prepared or able to offer to purchase subscriber accounts or increase the amount of investment to create a new subscriber. The effect of competition may be to reduce the purchase opportunities available to us, or to increase the price we pay for or invest in subscriber

18

accounts, which could have a material adverse effect on our return on investment in such accounts, and on our results of operations, financial condition, and ability to service debt.

We lose some of our customers over time.

        We experience the loss of accounts as a result of, among other factors:

•

relocation of customers;



•

adverse financial and economic conditions;



•

the customers' perception of value; and



•

competition from other alarm service companies.

        We may experience the loss of newly acquired or created accounts to the extent we do not integrate or adequately service those accounts. Because some acquired accounts are prepaid on an annual, semiannual or quarterly basis, customer loss may not become evident for some time after an acquisition is consummated. An increase in the rate of customer loss could have a material adverse effect on our results of operations and financial condition.

        During 2002 our change in focus from growth to strengthening our operations resulted in a net loss of 59,625 customers or a 5.3% decrease in our customer base from January 1, 2002. During 2001, attrition, our change in focus from growth to strengthening our operations, the disposition of certain accounts and adjustments related to the conversion of our customer base to our common technology platform resulted in a net loss of 197,657 customers or a 14.9% decrease in our customer base from January 1, 2001. While our attrition rate is decreasing, we continue to lose customers at a faster rate than our rate of adding customers. Some of the reasons for the decrease in attrition in 2002 are discussed in "ITEM 1, Business—Attrition," above. The net loss of customers was the primary cause of our decline in monitoring and related service revenues in the North America segment of $47.5 million in 2002 and $59.9 million in 2001. We expect this trend will continue until the efforts we are making to acquire new accounts and further reduce our rate of attrition become more successful than they have been to date. Until we are able to reverse this trend, net losses of customer accounts will materially and adversely affect our business, financial condition and results of operations.

Our customer acquisition strategies may not be successful which would adversely affect our business.

        The customer account acquisition strategy we are now employing relies primarily on our internal sales force and making alliances such as our strategic alliance with BellSouth. We have changed our acquisition strategy several times over the past few years attempting to decrease the cost of adding customers and to decrease the rate of attrition from new accounts. While our present strategy has resulted in some improvement in 2002, there can be no assurance that this strategy will be successful. If the strategy is not successful, our customer base could continue to decline. If successful, the selling costs related to this strategy will increase our expenses and use of cash. Failure to economically replace customers lost through attrition or increased cash needs could have a material adverse effect on our business, financial condition, results of operations, and ability to service debt obligations.

Increased adoption of non-response or verification-required policies by police departments may adversely affect our business.

        As noted under "Regulatory Matters" above, an increasing number of local governmental authorities have adopted or are considering the adoption of laws, regulations or policies aimed at reducing the perceived costs to municipalities of responding to false alarm signals. Such initiatives could increase the costs of providing our services, and consequently lead to less demand for alarm monitoring

19

services in general and increase our attrition. Additionally, we will incur greater costs in monitoring, evaluating and attempting to effect the outcome of these initiatives.

        One of these initiatives involves the City of Los Angeles where the Police Commission of the City of Los Angeles is attempting to institute a citywide verified response policy for residential and commercial burglar alarms. Approximately 6% of our residential and commercial recurring monthly revenue is derived from customers in the City of Los Angeles, and the adoption of such a policy could have a particularly adverse effect on us due to the significant concentration of our customer base in that city.

Declines in new construction of multifamily dwellings may affect our sales in this marketplace.

        Demand for alarm monitoring services in the multifamily alarm monitoring market is primarily tied to the construction of new multifamily structures. We believe that developers of multifamily dwellings view the provision of alarm monitoring services as an added feature that can be used in marketing newly developed condominiums, apartments and other multifamily structures. Accordingly, we anticipate that the growth in the multifamily alarm monitoring market will continue so long as there is a demand for new multifamily dwellings. However, the real estate market in general is cyclical and, in the event of a decline in the market for new multifamily dwellings, it is likely that demand for our alarm monitoring services to multifamily dwellings would also decline, which could negatively impact our results of operations.

We are susceptible to macroeconomic downturns which may negatively impact our results of operations.

        Like other businesses, we are susceptible to macroeconomic downturns in the United States or abroad that may affect the general economic climate and our performance or that of our customers. Similarly, the price of our securities is subject to volatility due to fluctuations in general market conditions, differences in our results of operations from estimates and projections generated by the investment community and other factors beyond our control.

ITEM 2.    PROPERTIES

        We maintain our executive offices at 818 S. Kansas Avenue, Topeka, Kansas 66612. We operate primarily from the following facilities, although we also lease office space for our approximate 60 service branch offices and 7 satellite branches.

PART II

ITEM 5.    MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

Market Price Information

        Our common stock is listed on the New York Stock Exchange under the symbol "POI", and continued listing on the New York Stock Exchange is subject to meeting its requirements. The table below sets forth for each of the calendar quarters indicated, the high and low sales prices per share of our common stock, as reported by the New York Stock Exchange. All prices are as reported by the National Quotation Bureau, Incorporated.

Dividend Information

        Holders of Protection One common stock are entitled to receive only dividends declared by the board of directors from funds legally available for dividends to stockholders.

        Other than a $7.00 cash distribution paid to holders of record of Protection One common stock as of November 24, 1997, to holders of outstanding options to purchase Protection One common stock and to holders of warrants exercisable for Protection One common stock, all in connection with the combination of the Protection One and Westar Energy' security businesses in November 1997, Protection One has never paid any cash dividends on its common stock and does not intend to pay any cash dividends in the foreseeable future. The indentures governing the 8¹/8% Senior Subordinated Notes due 2009, the 13⁵/8% Senior Subordinated Discount Notes due 2005, and the credit agreement relating to its Westar Credit Facility restrict Protection One Alarm Monitoring's ability to pay dividends or to make other distributions to its corporate parent. Consequently, these agreements restrict our ability to declare or pay any dividend on, or make any other distribution in respect of, our capital stock.

Number of Stockholders

        As of April 3, 2003, there were approximately 133 stockholders of record who held shares of our common stock.

Securities Authorized for Issuance Under Equity Compensation Plans

        The information called for by the item relating to "Securities Authorized for Issuance Under Equity Compensation Plans" will be set forth under that heading in the Proxy Statement relating to the Annual Meeting of Stockholders to be held May 28, 2003 which will be filed with the Securities and Exchange Commission no later than April 30, 2003 and which is incorporated herein by reference.
