The CHHF/A/HT heat detectors operate by using a matched pair of thermistors to sense heat.
One thermistor is exposed to the ambient temperature, the other is sealed. In normal conditions the two thermistors register similar temperatures, but, on the development of a fire, the temperature recorded by the exposed thermistor will increase rapidly, resulting in an imbalance, causing the detector to change into the alarm state.
Fixed heat detectors are set to trigger into the alarm state at the preset temperature threshold.
