Product Details for Nittan Sensortec Addressable Optical Smoke Detector (ST-PY-AS)
The Nittan Sensortec ST-PY-AS is an attractively-styled, low profile photoelectric sensor for use with Nittan ‘AS’ protocol control panels. Its aesthetically pleasing design enables it to blend unobtrusively into modern working environments.
The ST-PY-AS photoelectric 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
