Fire Alarm System (EN54)

Addressable Heat Fire Detector

A9020T

Product features

LPCB and CPR approval

It supports soft addressing and rewriting the address via coder in situ. 

Within a single-chip microcomputer, it can collect real-time data and then process it to realize a curve tracing for the field situation.

  • A9020T point-type heat fire detector (Detector hereunder) is a mated product of the SEC3002 fire alarm control panel. It uses a two-bus work mode. With an internal microprocessor, it supports electronic coding. The detector realizes real-time acquisition of the in situ temperature data and sends back the data to a fire alarm control panel. 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.
