Addressable Heat Detector is a mated product of the addressable fire alarm system. The detector realizes real-time acquisition of the in situ temperature data and sends back the data to a fire alarm control panel.It uses a two-bus work mode. With an internal microprocessor, it supports electronic coding.  It can also receive and execute the control commands given by a fire alarm control panel. When in a routing inspection, the detector indicator will blink. When there is a fire in the monitored area and the temperature has reached the alarm threshold, the fire alarm control panel will confirm a fire alarm according to the received message sent from the detector, and the detector indicator will light at the same time to indicate a fire alarm.


The detector is suitable for such industrial and civil buildings that have a great deal of heat when fire takes place, such as kitchens, boiler rooms, generator rooms, drying workshops and smoking rooms and is not suitable for places with a great deal of smoke but little heat.

Addressable Fire Alarm Heat Detector Features:

  • It can realize electronic coding and rewrite the address via coder in situ.
  • Within a single-chip microcomputer, it can realize real-time data acquisition and processing, realize a curve tracing for the field situation.
  • It has a temperature compensation function and a sensor fault detection function (fault reporting to fire alarm control panel).
  • Non-polarity, two-bus connection that ensures convenient installation and maintenance.
  • Designed with an upper cover and a lower cover and installed on an independent base, it can be installed, debugged and maintained conveniently.
  • Built-in remote indicator output terminal, drive remote indicator lit when fire alarm
