A9020T point-type heat fire detector (Detector hereunder) is a mated product of the fire alarm control panels. 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.
It supports soft addressing and the address rewriting via coder in situ.
Within single-chip microcomputer it can collect real-time data and then process it to realize a curve tracing for the field situation.
It supports temperature compensation and a sensor fault detection(fault reporting to the fire alarm control panel).
Non-polarity, two-wire bus wiring that ensures convenient installation and maintenance.
Designed with an upper cover and a lower cover and installed on a detector base, so it can be installed, commissioned and maintained conveniently and do not distinguish the connection line.
Built-in remote indicator output terminal, the output signal drives remote indicator light when fire alarm
