The shell is made of cast aluminum alloy, which has the advantages of low density, high strength, corrosion resistance and good casting process. The use of embedded technology and high sensitivity anti-poisoning gas sensors to maintain a constant alarm sensitivity. Flood protection: Intelligent overrange protection circuit. With two, four wire bus adaptive function; The four-wire working mode and the gas alarm controller are conventional connections. The two-wire mode is connected to the gas alarm controller bus output terminal.
