  • EZ access battery door
  • Battery backup, batteries included
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.

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 5 out of 5 by from The plug-in design is an excellent feature for any... The plug-in design is an excellent feature for any carbon monoxide alarm. According to an expert, I was told that carbon monoxide alarms should be place closer to the floor rather than up on the wall. This makes sense because carbon monoxide rises. Most electrical outlets are located close to the floor therefore the plug-in feature makes sense....plus you do not need to make any holes in the wall to attach the alarm.
