To whom it may concern;
I manage several properties in Mammoth Lakes, which all have remote fire alarm monitoring systems. Over the years I have learned I can rely on Sierra Security for early notification of potential alarms and maintenance of these systems.
Recently, I was in need of Sierra Securities services, which required an extensive upgrade to bring to code a newly installed elevator system. Without much notice, Sierra Security responded and installed the required fire, smoke and heat sensor system to satisfy both the Mammoth Lakes Fire Dept. and the State of California, so we could begin using the new elevator.
Sierra Security has been responsive to my needs on many occasions. They are thorough, precise and will do what’s needed to please their clients.
