SFD-860 series bus-type combustible/toxic gas alarm device, widely used in various places prone to dangerous gas leakage in high temperature areas, can monitor these places for a long time, once the surrounding combustible gas exceeds the standard leakage, the combustible gas detector installed in the explosion-proof scene will immediately send the detection signal through the transmission cable to the sound and light alarm device, when the gas concentration reaches the set alarm point, the sound and light alarm device will immediately send out the sound and light alarm signal to prevent fire, explosion and other incidents.
