The First Alert CO410 Battery Operated Carbon Monoxide Alarm with Digital Display is an easy to use carbon monoxide detector that comes with one carbon monoxide alarm, a user's manual, and two AA batteries. Symptoms of carbon monoxide poisoning are like the flu, and you might not even know you're in danger. That's why a carbon monoxide alarm is an excellent way to protect your family. It detects the CO you can't see, smell or taste in the air. This alarm uses an electrochemical carbon monoxide sensor, the most accurate technology available. It's easy-to-read back-lit digital LED display communicates a clear read-out of current CO concentrations in parts per million. It is powered by two AA replaceable batteries giving you peace of mind during power outages. The test/silence button both silences a non-threatening alarm and low battery warning and allows you to test the unit's functionality. The alarm performs its own internal test as well, and and re-alarms if carbon monoxide levels persist, sounding a loud 85-decibel horn. An esthetically pleasing premium shape is ideal for placing in all visible locations, with no installation required. It includes an optional wall mount, no outlet required. An audible and visual low battery signal alerts you to replace the battery. Meets UL standards. Code compliant.

Rated 5 out of 5 by Battery Powered Carbon Monoxide Alarm The alarm is easy to use, functional with minimum effort. July 1, 2014
Rated 5 out of 5 by Works great! Works as advertised. I feel much safer now with two CO detectors actively protecting my home. September 6, 2011
Rated 3 out of 5 by time will tell This CO monitor is just what I ordered.It was easy to install and the test mode worked fine. As far as performance,if it works I'll send you a raving review, if it doesn't work I probably won' be able to tell you how disapointed I am with the product. Bob January 24, 2012
Rated 5 out of 5 by Very good, but... Be careful when you open the battery compartment- you feel like you need to force it closed if you don't have the batteries in. Once you put the batteries in, it closes very easily. June 19, 2012
Rated 4 out of 5 by Good Value What can one say about a CO detector? I hope I never have to find out how well it works. It was easy to set up and install. The battery compartment lid is poorly designed. It opens easily but it doesn't close easily. If you try to force it shut you WILL break the arm that snaps it shut. You have to carefully pry the arm upward using a screwdriver as you shut it. Dumb design. But it works. Nice bright LED backlit display. AA batteries instead of 9-Volts - who keeps 9-Volts sitting around? Reasonable price. I'd recommend it. April 9, 2013
