Product Description:
The series of 485 main line gas detection alarm system adopts non-standard agreement or MOdBUS protocol for data collection and transmission.
This fixed nitric oxide uses the bus-system, having strong anti-jamming capability, convenient layout and simple wiring. At the same time, it also provides an controlling external device (exhaust fan, solenoid valve, etc.) of the switch output.
Product Features:
1 ) Imported sensors,has a good sensitivity and repeatability;
2 ) Simple menu operation,complete functions and high reliability;
3 ) Uses the bus wire system, having strong anti-jamming capability, convenient layout;
4 ) Provides an controlling external device (exhaust fan, solenoid valve, etc.) of the switch output;
5 ) Detects gas concentration with natural diffusion mode;
6) Adopts aluminum shell material with high strength, heat resistance and corrosion resistance.
