AC103HD
Conventional Heat Detector
The primary purpose of the AC103HD conventional Heat Detector is to measure the temperature presence in its surveillance area. It triggers an alarm signal to the fire panel in case of a sudden rise in temperature or abnormal temperatures.

What is a heat detector and how does it work?
Heat detector is an instrument that measures its ambient temperature. It will raise an alarm by monitoring the rate of rise of heat in its surveillance.
Heat detector consists of a thermistor component that measures surrounding temperature. The resistance offered by the thermistor device decreases with increase in heat sensed by it, thereby increasing the values of voltage and current drawn by the circuit. Detector’s intelligence algorithm monitors the difference in voltage values at continuous intervals of time. The higher the difference in voltage, the higher the increase in heat.
In case of fire, the rise in temperature is rapid. Meaning, in less time the difference in temperature measured is very high. This parameter of rate of rise in heat is considered to raise an alarm confirming presence of fire.
Further, alarm is also raised when the live temperature exceeds the pre-set upper limit/threshold values of the detector.
This detector is much more effective than fixed temperature detectors and is also unharmed by dusty or smoky environments.
