Product Description

The Kidde Carbon Monoxide Detector, Plug In Wall with AA Battery Backup, Test-Hush Button uses electrochemical sensor technology to detect poisonous CO gas in your home and alert you by sounding an 85-decibel alarm. Setup is easy as the Kidde carbon monoxide alarm plugs into a standard, 120V AC power outlet in your home, while two AA alkaline batteries (included) work as a backup in the event of a power failure. When carbon monoxide is detected, the digital display shows the level of carbon monoxide the alarm is sensing and updates every 15 seconds. Peak Level Memory records the last time carbon monoxide was detected or when the unit was tested. The Smart-Hush button silences the unit for approximately 8 minutes, which is helpful when this smoke detector carbon monoxide detector combo sounds from things like routine cooking or shower steam. Install a carbon monoxide smoke detector combo on every level of your home and near bedrooms to help keep your family safe. UL Certified with a 10-year limited manufacturer's warranty. Meets requirements of UL 2034, UL217, NFPA72, (chapter 11 2002 edition) The State of California Fire Marshal, NFPA101 (One and two family dwellings) Federal Housing Authority (FHA), Housing and Urban Development (HUD).

Super Easy Set up
Over all these were pretty easy to set up. I’m definitely the kind of person that will procrastinate if the set up seems like it will take too many steps. But these were super easy to install right after I got them out of the box. Obviously this review is for the easy set up! Glad to have a piece of mind with one of these in every room!
