The JA-80G detects mixtures of air and combustible gases or fumes (Natural Gas, Methane, Propane, Butane, Acetylene, GPL, Hydrogen, etc). The detector detects two levels of gas concentration, responding with two different reactions. The mains-powered detector indicates a gas leakage optically, and acoustically, and transmits alarm wirelessly via Oasis protocol.
