The Kidde AC Plug-In Carbon Monoxide Detector with Battery Backup and LED Light Indicators, model 900-0263, provides easy installation and peace of mind. The carbon monoxide alarm plugs directly into any standard AC wall outlet and two AA batteries provide reliable detection of carbon monoxide during power outages.

In the event of an incident of carbon monoxide gas, the Kidde alarm will sound an 85-decibel alarm with 4 loud beeps, plus a red LED light will illuminate. The Kidde 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 protection, place one carbon monoxide detector on each level of your home and in or outside each bedroom. UL Certified with a 10-year limited warranty. Meets requirements of UL 2034.

Backup batteries included, super simple to test and just plug in! This replaces an old one we had. Dont forget these things expire replace your old ones, this one is 10 years after installing. Theres really no way I can personally test it with Carbon monoxide, but I definitely feel safer with our fireplace. I ordered from Walmart.com and they delivered it to my house in the country few hours later. Originally said it would be days to ship. Thats service!
