Our fire alarm was not up and functioning, and none of us knew how to operate it. CPR came and performed a thorough analysis, and identified and repaired several problems, even though it had been originally installed by others. This is a big alarm system on a big building; actually it's two buildings with a total of over 14,000 sq. ft. There are many zones, with multiple types of alarm activators - pulls, smokes, smoke beams, rate of rise, etc. They expertly revived the entire alarm system and have it running flawlessly. They then installed a state of the art burglar system, also with many zones and functions. The technicians at CPR are truly expert, and Carmen will not stop until you are completely satisfied and happy with the work. Everyone at CPR has only your best interest in mind. I highly recommend CPR Electric and Alarm.
