The Kidde Carbon Monoxide Detector, AC Plug-In with Battery Backup, CO Alarm with Replacement Alert, model KN-COB-DP2, plugs directly into any AC wall outlet, while 2-AA batteries provide reliable backup detection of carbon monoxide, even during power outages. CO is often called the “invisible killer” because you can’t see it or smell it, and in large concentrations it can be fatal, so having working carbon monoxide detectors is vital. The compact design means that when you plug in the carbon monoxide detector to a standard wall outlet, you’ll still have space to use the second outlet.
When the CO alarm detects carbon monoxide gas, 4 loud beeps will sound to alert you to the danger and a red LED will illuminate. The CO detector also features a Replacement Alert, which chirps 2 times every 30 seconds to indicate that it’s time to replace the detector. For whole-home family detection, place one carbon monoxide detector on each level of your home and outside each sleeping area. UL Certified with a 10-year limited warranty. Meets requirements of UL 2034.
