Product description
The RS485 four wire gas alarm detector adopts ModBUS protocol for data collection and transmission.
With output relay It also provides an controlling external device (exhaust fan, solenoid valve, etc.) The detector detects gas concentration with natural diffusion mode, which uses the imported sensors and has a good sensitivity and repeatability.
