Exhibit 99.2

Dear Colleague:

Earlier this afternoon, we issued a press release announcing that Tyco has signed a definitive agreement to acquire Brink’s Home Security which operates under the name Broadview Security. The stock and cash transaction is valued at approximately $2.0 billion. You will be seeing and hearing more about this acquisition in the media and elsewhere in the coming days but I wanted to share with you some of my thoughts about this transaction and the benefits of combining Broadview with our ADT North America business.

As you know, we have consistently talked about continuing to improve our operating performance across the company while also looking for opportunities to strengthen our presence in our global Security, Fire and Flow Control platforms. While we have focused mostly on smaller bolt-on acquisitions to enhance our product and service offerings to our customers, our financial strength and flexibility allows us to consider larger opportunities like the acquisition of Broadview.

I am very excited about this acquisition. By combining Broadview with ADT, we have an opportunity to strengthen our position in the important and highly competitive North American residential and small business security industry. Additionally, this acquisition complements our efforts to increase our service revenue which today represents about 40 percent of Tyco’s total revenue. Service revenue has been a source of stability and consistency for our company, especially during these uncertain economic times.

Broadview was spun off as a separate public company from its former parent The Brink’s Company in 2008 as a full-service provider of residential and commercial security systems. Broadview markets, installs, services, and monitors security alarm systems to approximately 1.3 million residential and small business accounts throughout North America, and generates annual revenues of approximately $565 million. Similar to our ADT operations in North America, Broadview is a well-managed business with a strong operating platform and good returns.

With our complementary products and services, this acquisition is an excellent strategic fit. As we integrate these businesses under the ADT name, we will continue to focus on growing our account base and expanding our service offerings. Customer service will continue to be a top priority for the combined business.

The acquisition is subject to regulatory review and approval by Broadview’s shareholders and we are targeting the second half of fiscal 2010 for closing. During this period, the ADT North America and Broadview teams will begin the integration planning process for combining the two companies.

This transaction provides us with an exciting opportunity to bring together two premier companies in the security industry to deliver great products and services to our customers and to generate solid long-term returns for our shareholders. For more information about today’s announcement, I encourage you to read our press release at www.tyco.com.

Regards,
