Heat Detector (Model D-103-3)

HEAT DETECTOR (MODEL D-103-3)

DEMCO Heat Detectors D-103/D-103-3 employ the principle of electrothermodynamics, the science of relation between heat and electromechanical works. They are professionally designed to work reliably with most fire detection system with central control equipment. These units feature a double stage fire detection by employing two distinct methods: Rate-of-Rise and Fixed Temperature, both of which are open circuits designs designed to close an electrical circuit open activation. The DEMCO D-103/D-103-3 Heat Detectors meet the requirement of UL521. Read More
