Heat Detector A9020T
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 is a mated product of the SEC3002 fire alarm co ntrol panel. It uses a two-bus work mode. With an internal micro-processor, it support electronic coding. The detector realizes real-time acquisition of the in situ temperatur e data and sends back the data to a fire alarm control panel. It can also receive and exe cute the control commands given by a fire alarm control panel.
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.
