The First Alert CO400 Carbon Monoxide Alarm utilizes an electrochemical carbon monoxide sensor that lasts for up to five years to detect carbon monoxide. This carbon monoxide detector is battery powered, making it portable and easy to use anywhere, even in the event of a power outage. When carbon monoxide levels become elevated, a loud 85-decibel alarm alerts you to the threat.
The Most Accurate CO Sensor Available
The First Alert 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.
Comprehensive Warning Features
When carbon monoxide levels rise, the carbon monoxide detector sounds 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. Each CO detector lasts approximately five years.
Simple and Easy to Use
The First Alert Carbon Monoxide Alarm is easy to set up. Simply insert the battery, 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 of 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.

Received the item on time and it works as expected. Happy with my purchase thus far. One item to note: the placement of the screw holes in this model has changed in recent years, so while I was trying to avoid having to drill new holes by purchasing the same model as I was replacing, I did have to accommodate the change in design.
New CO400 to replace old CO400

Very good unit to purchase. One thing to note. The model number was the same as old CO detector we had, however new one would not mount on old mounting brackets. The screws were at different lengths so had to drill more holes in the wall. Would be nice if the model number had consistancy.

This new CO detector is excellent. It replaces my previous CO-400 which needed to be retired after 8 years of reliable service. It makes sense to stay with a winner. The First Alert Store was a pleasure to deal with and they had my new detector in my hands within a week.
So far so good
