Thermodiferential Fire Detector 802271 with base 801590



TD 802271Esser is an thermodiferential fire detector, from the series of IQ8quad detectors. The detector is used to detect fires with fast and slow temperature rise. Fire detection with rapid temperature increase is achieved through fast semiconductor sensor of the temperature increase while fire detection with a slow increase in temperature is achieved by using the thermal switch with fixed folding temperature. They are suitable for areas where in the normal operation smoke or other aerosols appear (that respond to smoke detectors), but with an open fire, or the rapidly developing one it will execute the alarm.

Series of analog process detectors features:
-         Decentralized intelligence
-         The function of self-control
-         Automatic adjustment of conditions in space
-         Store the alarm information and operating data
-         Automatic addressing
Activation of the detector is expressed by activating LEDs on the the detector.
