Customer Testimonials

Bill M.

I had a problem with one PIR which is a motion sensor. Erica was very patient with me on the phone and explained how I could bypass the zone in the interim until a technician was available to trouble shoot the problem. She expertly walked me through the process of programming the panel so I could still set my alarm by temporarily removing the troubled zone from the system. She set up an appointment for a tech rep to call me. I could not have done any of this without her help.

Vincent C.

Worked with Destiny recently and everything went incredibly smooth. She was very knowledgeable and maintained excellent communication throughout. Everyone I talked to at Alarm Relay was fantastic.
