Apollo Xp95 Heat Detector (A2S)

The XP95 Heat Detector (A2S) monitors temperature by using a single thermistor which provides a count output proportional to the external air temperature, reporting an alarm at 55°C.

Reliable fire detection in areas with a wide temperature range from -20°C to +70°C
Ideal for environments that are dirty or smoky under normal circumstances
Unaffected by wind and atmospheric pressure
