The First Alert CO600 Plug-In Carbon Monoxide Alarm utilizes an electrochemical carbon monoxide sensor that lasts for up to five years to detect carbon monoxide. This carbon monoxide detector plugs into any wall outlet. When carbon monoxide levels become elevated, a loud 85-decibel alarm alerts you to the threat.
Advanced Electrochemical CO Sensor
The First Alert CO600 Plug-In Carbon Monoxide Alarm uses an advanced electrochemical CO sensor to detect elevated carbon monoxide levels. When CO is detected, the carbon monoxide detector sounds an alarm to warn you of the threat. Carbon monoxide can’t be seen, smelled, or tasted in the air, and it is the leading cause of accidental poisoning deaths in America. Placing carbon monoxide detectors on every floor of the home and in each sleeping room is an important way to protect your family from danger.
Comprehensive Warning Features
This carbon monoxide detector features an 85-decibel siren that is designed to wake even the soundest of sleepers. A low-battery light and alarm alert you when battery power is running low, and an end-of-life timer lets you know when the device should be replaced. The CO detector lasts approximately five years.
Simple and Easy to Use
The First Alert CO600 Carbon Monoxide Alarm is easy to set up. Simply plug the alarm into a 120-volt wall outlet, and the CO detector will start to monitor your space for carbon monoxide. There are no complicated displays or settings to navigate–a single button silences the alarm and tests the CO detector. A pull-down action chart instructs you in what to do if the CO alarm goes off.
Where to Place Carbon Monoxide Alarms: One on every level of the home and one in each sleeping area.

Alarm for rentals
This is an excellent alarm for rental because it does not have a backup battery which a tenant might not replace when needed.

First Alert Plug-In Carbon Monoxide Alarm
We recently bought a condo and noticed there was an old carbon monoxide detector plugged in. After checking it out and realizing it was past its lifetime, we thought it would be a good idea to purchase a new one. After investigating the matter, it turned out the replacement was the First Alert. Can't believe we never had invested in one before. And it appears as though we chose the right detector from the right company. inexpensive and easy to install & maintain. Should never be without a carbon monoxide detector! Mike Swartz Creek, MI
