The Gas Detector is designed to monitor residential and commercial rooms. It can be used as a standalone device, or connected to the inputs of ABB intrusion and fire alarm control panels or ABB i‑bus® KNX devices. It requires an external power supply. The detector is also highly sensitive to combustible gases. It is suitable for monitoring combustible gases such as propane, methane and butane, as well as acetylene, city gas and natural gas.
