The SST Discovery Marine Heat Detectors have a common profile with ionisation and optical Smoke Detectors but have a low air flow resistance case made of self-extinguishing white polycarbonate.
The SST Discovery Marine Heat Detector uses a single thermistor to sense the air temperature at the detector position. The thermistor is connected in a resistor network, which produces a voltage output dependent on temperature. The design of the resistor network, together with the processing algorithm in the microcontroller, gives an approximately linear characteristic from 10°C to 80°C.
