May 16th 2016 I tested the Fire Alarm system at my dads Kingsport office with Simplex tech Andrew Crosby , the system consist of the 2099 series t bar pull stations the True Alarm smoke detectors the red wall mount True Alert horn strobes and the red wall mount True Alert strobes in the bathrooms and of course the duct detectors where needed and the annunciator. helping Andrew Crosby from Simplex was a blast !!!
