Our customers say it best:

"Thank you for the wonderful service you have provided me over the past 25 years ... At least 4 houses, if not 5, as well as my corporate office. Your staff has always been efficient and professional. On the recent hook-up in Redmond, I would especially like to compliment Boyd ... He had to ... move a lot of things ... I expected to come home to a mess, but everything was put back the way he found it (if not better!) Thank you."

Welcome to the PSI Family

Since 1970, Protective Systems Inc. of Seattle has been serving families, businesses and commercial facilities with security, fire and custom electronics. PSI stands for Pride, Service and Integrity - the cornerstones of our success.

At PSI, we’ve had the pleasure of serving some Western Washington families for a span of three generations. Can you think of a better testimonial to customer satisfaction and loyalty?

In addition to a full range of residential and commercial security/fire protection systems, PSI offers a full range of monitoring services to protect your home or business. Protective Systems Inc. is an authorized dealer for First Alert Professional, a Honeywell Company. First Alert is an elite network of independently owned security dealers. That means you get the “hands on” personal care of an independent business, backed up by the innovation and solid proficiency of First Alert and Honeywell, a Fortune 100 Company. PSI is also one of the few companies that can not only install, monitor and maintain the system - we are also licensed to perform commercial fire/sprinkler inspections.
