Basic Battery Operated Carbon Monoxide Alarm
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.

- The carbon monoxide alarm needs to be relocated. Carbon monoxide alarms should be located 15-20 feet away from all fossil fuel burning sources like furnaces and stoves. Alarms should be located 10 feet away from sources of humidity like showers.

First Alert Basic Battery Operated Carbon Monoxide Alarm - CO400 Reviews
Order process was simple and product arrived as scheduled. Installed the included battery, tested then mounted on wall where the old one was. Now I can only hope it works when necessary....fingers crossed that time never comes!! The previous one was replaced as a result of the end-of-life alarm feature. It was already in use when I moved into the house Nov 2016. I would reccommend.
Our carbon monoxide alerted us that it was at end of life. We quickly replaced it thru First Alert. We have been fortunate to never need the alarm but we know of friends who are still alive because their First Alert woke them up. The order process was so easy and efficient.
Ordered exact same model to replace. Easy to install with existing mounting screws.
Ordered product to replace expiring unit. Came very quickly, with an included battery and placed in previous position to protect the home. Great service.
Replaced the original with the same type. Fast shipping and easy set up. Will replace with same when needed. Love it!
As promised, order arrived quickly, in mint condition. and with clear instructions as to how to set up and use it. The alarm worked perfectly the first time, and I have no doubt it will last as long as the one it replaced.
I recently had to replace my First Alert CO detector. I decided to buy the same Model#. When did a Google search for that item, I was pleasantly surprised to find that the First Alert direct price was the lowest, and shipping was free. The whole ordering process was very easy, and I received the item quickly.
Ordered product directly for First Alert website...easy to navigate and simple order process. Received product within 3 days. Directions for install were thorough and straightforward.
I have ordered from this site before. It is easy to order and delivery is fast. Product arrived and is as described on the web site. Good product.
