Heat detector operates by using a matched pair of thermistors to sense heat. One thermistor is exposed to the ambient termputure, the other is sealed. In normal conditions, the two thermostats register similar temperatures, but, on the development of fire, the temperature recorded by the exposed thermistor will increase rapidly, resulting in an imbalance of the thermistors and causing the detector to change to the Heat Detector
