System Sensor 5621 Detector flame sensorsThe System Sensor 5621 is a commercial grade dual circuit mechanical heat detector designed for high reliability fire detection in environments where traditional smoke sensors are prone to nuisance alarms. This 135F fixed temperature and rate of rise heat detector utilizes two independent circuits to trigger both local alarm systems and auxiliary devices like fans or door closers. The Rate of Rise (ROR) element responds to temperature increases
