Welcome Sentry Protective Services Customers

Welcome to Wayne Alarm Systems: the new hub for Sentry Protective Services customers. 

Sentry Protective Services of Billerica is now part of Wayne Alarm Systems. We thank co-founders Jim and Cheryl Baker for the opportunity to provide service to their more than 1,000 customers. 

Jim Baker told Security Systems Magazine that he was “delighted that [Sentry] has been acquired by Wayne Alarm, a company that shares our values and culture.” With over 40 years of experience in the security industry, Baker will continue to work as part of the Wayne Alarm sales team. We have actually retained all of the Sentry staff!
