Nittan ST-H2-AS Standard Thermistor Analogue Heat Detector
Nittan ST-H2-AS Standard Thermistor Analogue Heat DetectorUnlike smoke detectors that detect the presence of smoke particles heat detectors only react to changes in temperature. The ST-H2-AS is a Thermistor based Heat Detector which uses electronic components that change their resistance when heated this change is detected by circuitry within the detector.Key FeaturesThermistor Heat SensorOmniview 360Direct replacement for ST-H-ASRobust Fully Modulated AS Communications ProtocolEEPROM addressed Address stored in on-board EEPROM programmed by handheld programmer
