Product Description
Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you're in danger at first. That's why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can't see, smell or taste in the air.
The First Alert CO400 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. The permanent sensor lasts up to five years. It is powered by two AA replaceable alkaline batteries giving you peace of mind even during power outages. The test/silence button both silences the alarm and allows you to test its functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. No installation is required and the attractive design allows the unit to be placed anywhere you need it. It includes an optional wall mount with no outlet required. An audible and visual low battery signal alerts you to replace the battery. Pull down action chart has convenient guide on what to do if an alarm sounds. 5 year limited warranty. UL listed. --Bree Norlander

Placed one on each floor, near our bedrooms. They were easy to mount, and seem to work, batts are included. Small price for piece of mind.

The First Alert CO400 model battery powered carbon monoxide alarm is cheaply made. Installed in my apartment a little over a year ago by the seller when I purchased it, the alarm was new, and I haven't had any reason to so much as glance at the device.
However while trying to determine which device was making sounds indicating it needed a new battery, I turned my attention to the First Alert alarm. I pressed in the dual-purpose button in the center on the top to test the product and the alarm began to sound. Immediately, realizing this was not the device in trouble I went to silence the alarm by pressing on the lower half of the same button. I applied hardly any pressure but--and I can only assume this--the plastic arm on the inside of the alarm used to apply pressure to the internal buttons snapped and I was left with a useless alarm.
I'm not sure how First Alert's other products are built, but you get what you pay for.
If looking at First Alert's products, I would not recommend this alarm, I'm sure they sell higher quality products for a little more money.

These seem like nice detectors. I put one on each level for added protection. There are some limitations on placement such as further than 5' from any cooking appliance, 20' from any gas burning appliance, etc. But, after figuring that out, mounting them was easy.

I purchased this device to measure carbon monoxide on my sailboat. Nowhere in the description of the product does it state that it is not suitable for marine use. Upon receipt, the instructions specify that it is not for marine use. In addition, I wanted to know if it actually responded to carbon monoxide, so I intended to put it in the garage with my car running. Whoops, you cannot do that either. It has a notice that says that if you try testing the device as I intended, it will void the warranty.
Now, do you think I should use this in my boat to protect my family?
Probably not.

I bought 2 because new regulations in my state require one within 10 feet of each bedroom and I'd only had one on the first floor before. Good price, easy to install.
