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 SCO5CN carbon monoxide and smoke alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. The alarm uses photoelectric smoke sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. It is also great for sensing slow smoldering fires quickly. The permanent sensors last the lifetime of the alarm. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The alarm uses different 85-decibel horns and lights depending on whether it's alerting you to smoke or carbon monoxide. A low battery signal alerts you to replace the battery and end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 5-year limited warranty. UL listed. Not available for sale in Massachusetts.--Bree Norlander

I needed to replace a couple very old smoke detectors and decided to upgrade to a smoke and carbon dioxide detector. One of the problems with old smoke detectors is they use 9volt batteries which also are difficult to replace as well as expensive. This new First Alert dual smoke and carbon dioxide detector uses 2 AA batteries and has a separate battery compartment which allows you to replace the battery without taking the detector off the ceiling. Cheaper batteries and much easier to replace them. The cost at Amazon was only and nicely cheaper than anywhere. All-around good service from Amazon. Very satisfied customer here.

I have rental properties and I decided to upgrade all units to have monoxide detectors. I decided on this unit because it is a two in one device and it used double AA batteries instead of the nine volts. My tenants keep complaining that these devices keep beeping. I looked on the back and 3 chirps = bad detector. I took a few of them down, put up the old ones and brought them to my home. They have not chirped since. Something about the other place is making these detectors fail.

Another thing is that I did not notice this but there is a 5 year life on these detectors and then they will chirp without any choice but to replace them. So even if yours works at first, you only will get 5 years out of it. I bought a total of 7 of these that cost me a few hundred and now I need to look for replacements. I wish I left all the old smoke detectors in.
