DR-ZJ108 Gas Alarm Controller

The gas controller samples the analog signal generated by the Gas Detector, and after the data processing of the internal single-chip microcomputer, it can display the concentration, status (sound and light alarm), physical address and other information of the Detector in real time, and output the control signal. It has a complete fault self-detection function, which can display the fault location and type (sound and light alarm) of the system and sub-address in real time.

The design of this product follows the national standard of GB16808-2008, compared with traditional products, with new functions such as clock display, alarm time checking, independent setting, etc., and the system appearance is beautiful, the display interface is intuitive, the definition is high, and the operation of each function has the corresponding icons to match, the operation is very simple, and the whole product design adopts centralized control, which is convenient for query and maintenance.
