About this product

The Kidde Carbon Monoxide Detector, AC Plug-In with Battery Backup, Digital Display, Pack of 4 (model KN-COPP-3) features sophisticated sensor technology to help protect you and your family from the dangers of carbon monoxide. When the CO alarm detects carbon monoxide gas, 4 quick beeps will sound, followed by 5 seconds of silence, then the beeps will repeat; a number reading will appear on the digital display that measures the CO concentration. These CO levels will be stored in the detector's memory until it is reset. The digital display also provides a low battery warning by sounding 1 alarm per minute and displaying "Lb" on the screen. Operating with an AC plug-in, the CO detector can be easily installed directly in any AC wall outlet, or on a shelf or table with the included 6' power cord. It also has a 9V battery backup, which allows the carbon monoxide detector to provide continuous protection from CO gas, even during power outages. A red dot will appear in the lower right corner of the carbon monoxide alarm to indicate that the CO detector is operating as expected. For whole-home detection, place one carbon monoxide detector on each level of your home and near every bedroom. The Kidde AC plug-in carbon monoxide detector with battery backup is UL Certified with a 10-year limited warranty. Meets requirements of UL 2034.
