DEVCON SELLS ITS WHOLESALE MONITORING OPERATION

BOCA RATON, Fla., June 27, 2006 — Devcon International Corp. (Nasdaq: DEVC) today announced that in accordance with its plans to focus on providing security services to subscribers who have contracted directly with the Company, it has sold its Boca Raton-based third party monitoring operation which has operated under the name Central One and the associated Boca Raton monitoring center that it acquired from Coastal Security Systems to Lydia Security Monitoring, Inc., a New York corporation, operating under the name C.O.P.S. Monitoring, for $5.0 million in cash. The third party net recurring monthly revenue included in this transaction amounted to approximately $325,000 leaving Devcon currently with approximately $84,000 of third party recurring monthly revenue. During the next few months, Devcon and Lydia will be having discussions as to the terms and conditions under which the remaining third party recurring monthly revenue may be acquired by Lydia. As a result of this transaction, Devcon will now operate from two monitoring center locations, one in Hollywood, Florida and the other in New York City.

Stephen J. Ruzika, Devcon’s President and CEO, stated, “The sale of the third party monitoring operation will allow us to focus our efforts on providing enhanced services to customers who have contracted directly with us. Beginning today, we will no longer need to expend resources on the provision of third party monitoring services, allowing us to further streamline our monitoring center and administrative operations which, when complete, should lead to increased operating margins.” In addition, Mr. Ruzika stated that “C.O.P.S. Monitoring has been successfully providing third party monitoring services for dealers on a nationwide basis for many years. We believe that our dealers and certain of our employees are being placed in good hands and will be well-served in the years ahead.”

James McMullen, President and COO of C.O.P.S. Monitoring, stated, “Central One has certainly established itself as a true leader in today’s wholesale alarm monitoring marketplace. The level of professionalism and respect it commands is well deserved. This particular strategic acquisition firmly establishes the presence of C.O.P.S. Monitoring in the southeast, and fits ideally with our ‘hub and spoke’ regional approach to delivering unparalleled high-quality alarm monitoring services throughout the nation.” Mr. McMullen added that “over the course of the next year, alarm dealers of both companies will benefit from the very best features and services of each company, creating an even stronger C.O.P.S. Monitoring.”
