Product Details for Nittan Sensortec Addressable Heat Detector (ST-H2-AS)
The Nittan Sensortec ST-H2-AS is an attractively-styled, low profile heat sensor for use with Nittan ‘AS’ protocol control panels. Unlike 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.
The ST-H2-AS heat sensor has two terminals for connection onto the two wire loop. The remaining terminal provides a switched current sink function which operates when the sensor goes into alarm condition, suitable for the operation of an auxiliary function such as a remote indicator. Terminal 3 (RIL) is limited to 2mA.
A variety of bases are available for use with the ST-PY-AS sensor. It is important to use the correct base for each application. The available base models are:
- UB-4 base: for standard use with ST-PY-AS series sensor.
- STB-4SE base: Similar to UB-4 base, except deeper
