The RB-KZI combustible gas alarm controller is a high-tech product developed by our company. It can be matched with the RB-TZII point detector developed by our company to form a gas alarm control system and can be connected to secondary (or DCS) instruments. The controller unit receives the RS-485 signal transmitted by the detector unit, processes and logically analyzes it, and reflects it in the form of digital display, sound and light alarm, and links it with the connected fans, magnetic valves or other fire-fighting equipment
