Description
The First Alert CO400 Carbon Monoxide Alarm utilizes an electrochemical carbon monoxide sensor to monitor your space for a carbon monoxide threat. The battery-powered design doesn't require an electrician; simply insert the included 9-volt battery, and the carbon monoxide detector is ready to go.
The advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, such as faulty fuel-burning appliances, blocked chimneys, and generators running inside or too close to homes. When CO levels become elevated, a loud 85-decibel alarm alerts you to the threat.
Because CO evenly distributes itself, it's important to have a CO detector on every level and in every bedroom of your home. Designed to be simple to use, the CO detector has just one button that silences or tests the unit, as well as an end-of-life timer that lets you know when it's time to replace the device.

The battery door was nearly impossible to open. The instructions say to press the test button after installing battery and the “chirp” was so loud I lost my hearing for an hour.

Just wanted to post regarding the life of the unit. It started chirping 5 times the other night. I got it a new battery and same thing. The back states that 5 chirps means end of product life, so that feature works. Product is marked 2/2015 and it chirped a few days ago and I think had a battery in it the majority of that time. No issues with it while it was working. I couldn’t even say if I changed the battery on it (which is also a feature) so it isn’t a battery-sucker.

Purchased to replace same units from 8 years ago. Always reliable, but wish they still used always cheaper and always on hand, AA batteries instead of 9 v.

We were replacing a plug in monitor, and that was what I thought I was purchasing. We will keep this one, but prefer the other type.
