DEMCO Rate Of Rise/Fixed Temp Heat Detector 135O F C/W Standard Base, 12V-24Vdc

Heat Detectors D-103/D-103-3 employ the principle of electro thermodynamics, 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 Heat Detector is a combination rate-of-rise and fixed temperature detection. A temperature increases at the sensor of 15°F (9°C) or more per minute activates the rate-of-rise feature. This closes the contacts in the sensor to transmit the alarm condition to the fire alarm control panel.
