Model QB2200 - Dual Channel Gas Alarm Controller
From Gas Alarm Controller
The dual-channel alarm controller is a multi-point monitoring gas alarm system developed by our company. It consists of a controller and a detector. It is used to detect the concentration of flammable gas in the working environment. It can carry multiple gas detectors and simultaneously multi-point. Perform centralized collection. The system uses a 32-bit high-performance microprocessor as the control unit, using RS485 and (4 ~ 20) mA two communication methods, the response speed is fast. When the detected gas concentration in the ambient air reaches or exceeds the preset alarm value, the controller immediately emits an audible and visual alarm to remind the safety measures to be taken in time, and to control the driving of the exhaust or other peripheral equipment to prevent the occurrence of a fire accident. Guarantee the safety of life and property.
The system can be widely used in the canteens, liquefied gas stations, gas stations, spray booths and other places where gas is easy to leak for safety detection and alarm.
