The alarm is automatically deactivated when the gas concentration drops below the alarm threshold. applications of the maxi gas detector: kitchens and bathrooms equipped with gas appliances e.g. Cookers stoves water heaters boiler rooms with solid fuel or combustible gas fired stoves rooms with gas appliances such as: gas meters cylinders tanks gas pipes (basements corridors) portable gas heaters in domestic rooms with coal or wood fired stoves in public places **illustrative photos.
