The K7CO is Kidde's UK and European CO alarm family, not the US version.

The K7CO record is a battery-powered carbon monoxide alarm (10-year sensor, two supplied AA batteries) sold for the UK and continental-European markets, where alarm certification, standards and placement guidance differ from the United States. Our dataset records no verified United States-market offering of the K7CO, so no retailer, price, stock or warranty claim is made. Kidde's documented United States reference is the COB10 battery alarm (10-year sealed battery), linked below. Remember that a CO alarm never makes indoor generator use safe: combustion generators always stay outdoors, away from doors, windows and vents.
