Major Features
● Bus signal transmission, strong system anti-interference capability, cost-efficient wiring, convenient and efficient installation;
● Real-time gas concentration (%LEL) monitoring interface or time display interface for user’s choice;
● One-button start for simple and convenient system commissioning;
● Freely setting the alarm values of the two alarming levels in the full-scale range;
● Automatic calibration, and automatic tracing of sensor ageing;
● Automatically monitoring failure; correctly showing the failure location and type;
● Two sets of programmable internal linkage output modules and two programmable emergency buttons to automatically or manually control external equipment;
● Strong memory: historical records of the latest 999 alarming records, 100 failure records and 100 startup/shutdown records, which will not be lost in case of power failure;
● RS485 bus communication (standard MODBUS protocol) interface to realize communication with the host control system and networking with the fire and gas network system, to improve system integration.
