Product Introduction
The gas detection alarm controller is used to detect the content of combustible or toxic gases in the air, and supports four-bus or 4-20MA detectors, while centralized control of multiple points. The system uses a microprocessor as the control unit, when the concentration of combustible or toxic gas in the environment reaches or exceeds the preset value, the controller immediately sends an audible and visual alarm, and the relay can drive the exhaust air or other peripheral actions to prevent explosion and fire accidents, so as to protect life. The system can be widely used in factories, oil depots, liquefied gas stations, gas stations, gas stations, painting rooms and other places that need fire and explosion protection, safety monitoring and alarm
