The First Alert CO605 Carbon Monoxide Plug-In Alarm with Battery Backup 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. The CO605 easily plugs into any standard outlet with no additional mounting necessary. Powered a single 9-Volt replaceable battery, you will have the peace of mind that the alarm will work even 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. This alarm uses an electrochemical carbon monoxide sensor, the most accurate technology available. The electrochemical sensor continuously monitors CO levels and re-alarms in case of persisting dangerous levels. The alarm performs its own internal test as well, and re-alarms if carbon monoxide levels persist, sounding a loud 85-decibel horn. The back access battery compartment lets you change the 9-Volt battery conveniently. 7-year limited warranty. Meets UL standards.

Customer Reviews

Plug-In Carbon Monoxide Alarm with Battery Backup is rated 4.3 out of 5 by 55.
Rated 5 out of 5 by from necessary device Carbon Monoxide devices are required in homes & offices where non-electric fuels are in use. So easy to forget about this! We've had great dependability with this model at home (husband is retired fire dept, so the research was deep) & I was happy to find it online!

Rated 5 out of 5 by from Well-made product received earlier than scheduled. This product was as described and is easy to install, basically plug-and-play after installing the backup battery. Well-lit indicator shows exactly where unit is all the time, specially in the dark.

Rated 3 out of 5 by from Included batteries didn't work Fine once I changed the batteries - four out of the six I bought included batteries that were already low in charge.

Rated 5 out of 5 by from Excellent product--just what I wanted Very pleased with the carbon monoxide detectors. Just the quality one would expect from Home Depot. Shipping was prompt. It's always a pleasure shopping Home Depot, whether online or in the store.

Rated 3 out of 5 by from Bad product This plug in model does not even last 5 years, beeps ON and OFF even with new expensive lithium battery. I throw it away and buy other brand.
Date published: 2016-09-07
Rated 5 out of 5 by from easy to install. works great! Great product. Attractive and easy to install. All you have to do is plug it in.
Date published: 2014-04-29
Rated 4 out of 5 by from First Alert CO2 Detector As far as these devices go, this one seems to be good. The only thing I wished it had was a digital readout, but this can make you want to check it too often also. So, for the price, this one is worth the money spent.
Date published: 2014-12-11
Rated 5 out of 5 by from Nice and Easy! It was as simple as plugging it in. I bought these for my home that I just sold. No hassle and good price.
