I've been in the fire alarm industry for the past 17 years. The company I work for has done business with SAS for the better part of 20 years. I personally have done business with SAS for the past 7 years. They have a courteous and professional office staff. Knowledgeable and timely service. Their technicians have consistently stayed on the cutting edge of industry changes and their installation is top notch.

Thanks for all the great work.

I have had a long-term (30 plus years) working relationship with SAS Security Alarm Service. SAS has always done a great job and continues to do so after all these years.  Their installers are great to work with. They are very compassionate about their job. Please let them know.  Thanks for a great job and great service.

After taking over as the Program Director for Construction / Facilities with Metrocare Services, I continued the long standing contract with SAS after meeting one on one with Marty Graves.  Always there every step of the way.  When we need them to install a new card reader system, full building alarm system or remove and relocate an alarm package, we are assured we’ll get the best price and they show up when they say they’re going to be there.  The crew is patient with explaining new equipment and always able to lend a hand when the system needs a tweak.  Can’t say enough about how happy we are here at Metrocare Services to be associated with such a well-respected group of professionals.  Recommend them highly.
