The First Alert CO615 Carbon Monoxide Alarm is an easy-to-install, UL-listed alarm that combines advanced technology with a user-friendly design. 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 carbon monoxide alarm utilizes an electrochemical carbon monoxide sensor, the most accurate technology available. A single test/silence button, silences non-threatening alarms, low battery warnings and allows you to test the unit's functionality. It’s easy-to-read backlit digital LED display gives you a clear read-out of current CO concentrations in parts per million. A remote mute silences nuisance alarms by pressing any button on a standard household remote control (remote not included). Installation of the CO615 is as simple as plugging it in to any wall outlet and it comes with a plug-in cord, offering multiple placement options. The CO615 alarm includes a battery back-up, giving you peace of mind in a power outage. An end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 7-year limited warranty. UL listed.

Rated 5.0 out of 5.0 by Gets the job done Easily plugs into the wall. Needs batteries, too, to operate. Shipped quickly. July 24, 2012
Rated 5.0 out of 5.0 by easy to install Looks good low to floor after easy installation. Has a light at night. It is small and not noticeable. August 21, 2013
Rated 5.0 out of 5.0 by So far, so good This CO detector was easy to install and seems to be working fine. I wanted one that does not use batteries at all, but this is the closest I could come, and it was a recommended model. One I purchased several years ago consumed the batteries like it was not even plugged in, even setting the alarm off in the middle of the night. Eventually, I had to throw it away. Only time will tell if this one performs properly. So far, so good. December 27, 2012
Rated 4.0 out of 5.0 by This unit was highly rated by Consumer Reports I was disappointed it was not carried in the store, but pleased that it was available online. Don't set it on top of a warm surface, like a water heater-it will melt the plastic. November 26, 2011
Rated 3.0 out of 5.0 by Battery backup a great feature. Just pluged in the unit ,seems to work ok. Hope I don't ever need it. January 25, 2014
