Great small life saving device to rooms with solid fuel boilers and fireplaces. Also good to garage. No other gasses won't affect it, becouse of very good CO detector in a device. And it has Temperature sensor inside. Sense only CO. Description of alarm at the back of the cover.
It is Z-Wave Plus device and radio range, with my tested unit is great (Across my house).
