Addressable Heat Detector


Addressable Intelligent Heat Detector

This detector monitors the level of heat in its surveillance. It switches to alarm state when high rate of rise in heat is monitored, or also when the live temperature value exceeds its pre-set threshold value.This detector with a unique ID communicates to the control panel by pin pointing its exact location. Its unique feature is to provide the live temperature to the control panel for real time monitoring purpose.

Exclusive Features
  • Real time temperature info
  • Heat sensitivity alteration from the panel
  • Address can be changed from the panel
  • Detailed location description settings
  • Soft addressing
  • Pre alarm
  • Contamination alarm
  • Remote test facility from the panel
  • Electrical supervision
  • Transient voltage protection upto 2.4KV
  • Corrosion protection
  • Dual bi-color LED indication for 360° viewing angle
  • Easy to maintain/service

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.
