Major Features
● Four sets of bus loop transmission, 256 monitoring points, strong system anti-interference capability, partition management, cost-efficient wiring, convenient and efficient installation;
● 7 "high resolution true color LCD, similar to windows operating system, convenient and efficient menu operation, real-time one screen display of alarm information, failure information, concentrations at detectors, etc., types of gases shown in Chinese, free setting of alarm positions, convenient system query and maintenance;
● Free setting of two level alarm values and three alarming types (rising/falling/two-level) to improve system monitoring function;
● Strong memory: historical records of the latest 1,000 failure records, 1,000 alarming records and 100 startup/shutdown records, which will not be lost in case of power failure;
● Automatically monitoring failure; correctly showing the failure location and type; shielding (or isolating) any detector or module according to the user’s choice, convenient for on-line system maintenance;
● Strong logic programming and free configurations of output modules can realized remote automatic control over various kinds of external equipment; eight programmable emergency buttons can manually output control signals;
● Manually/automatically printing and adding real-time data records;
● Setting operating authorities for various users to realize level-based management and avoid misoperation;
● 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.

Panel Marks And Mounting Instructions
● Make 4 mounting holes (hole depth: ≥40mm) in a wall as per the requirements for bottom board mounting holes (hole symbols 1-4);
● Insert a plastic expansion bolt into each mounting hole;
● Fix the bottom board onto the wall, and fasten it onto the expansion bolts with 4 self-tapping screws (ST3.5×32);
● Hang the welding hanging parts on the back of the controller onto location A at the bottom board to complete mounting of the controller.
