Product Introduction
The four-bus gas detection and alarm controller is used to detect combustible or toxic gases in the air. It supports PowerBus two-bus detectors and multi-point centralized control. The system uses a microprocessor as its control unit. When the concentration of flammable gas in the environment reaches or exceeds the preset value, the controller immediately issues an audible and visual alarm, and its relay can drive exhaust fans or other peripheral devices to help prevent explosions and fire accidents and protect lives.
The system is widely used for safety monitoring and alarm in places that require fire and explosion prevention, such as factories, oil depots, liquefied gas stations, gas stations, gas filling stations and spray booths.
