The Kidde Plug-In Carbon Monoxide Alarm with 9-Volt Backup connects directly into a wall socket for quick and easy installation and protection from tasteless and odorless carbon monoxide gas. This alarm continues to provide protection in power outages as it includes a 9-volt battery backup. It offers a low-battery warning in case the battery needs replacing. Green and red LEDs visually indicate the status of the alarm and a tamper-resistant feature alerts you to when the unit has been removed from the socket.

  • Wireless design plugs directly into a standard wall outlet making installation quick and easy
  • Low-battery hush silences low-battery chirp warning for up to 12 hours in order to maintain protection without having to replace the battery at an inconvenient time
  • 9-volt battery backup provides protection during power outages
  • Tamper-resistant feature triggers constant alarm mode if it has been unplugged or has come loose from the outlet
  • Battery pull-tab helps reduce battery installation time and keeps battery fresh

Rated 3.8 out of 5 by 55 reviewers.
Rated 2 out of 5 by Would not reccomend Bought this about 1 year ago. One day it went off like there was carbon monoxide. My others (different brand) did not go off. I checked the Kidde model and took it out to fresh air and removed battery. Still was going off for a few minutes. I let it sit in the garage for over 6 months, Today I put in a brand new battery. It did the same thing as before. It will not shut off. Can not return it because I don't have the recipe. Im out 30 bucks. I would not recommend buying this product. November 25, 2014
Rated 5 out of 5 by awesome product fantastic idea with a ten year battery more dead battery beep in the middle of the night. So easy, just take out of the package and plug in. August 27, 2014
Rated 5 out of 5 by Would purchase this product again! We purchased this product 7 years ago and when it reached the end of its life, it let us know with an intermittent beeping. With all of the items we need to take care of every day, it is nice to come across an item that takes care of itself! Easy installation and you never know it's there. Be careful when reading the other reviews, operator error seems to be the problem with some of the bad reviews...for instance, the instructions say not to place the item in a kitchen setting as it can remit an alarm due to what's happening in the kitchen! We will buy this product again and again! January 1, 2013
Rated 1 out of 5 by Poor choice It worked for about three weeks then it started beeping intermittently, like when the battery is dead. I tried 2 other new batteries and it wouldn't quit the beeping. Returned it. February 18, 2014
