Count Per Pack

Absolutely not!! You need both. Your smoke detector will not in most cases detect carbon monoxide and vice versa.

NO. While there are more expensive models on the market that provide both CO detection/alarm and smoke detection/alarm, this inexpensive unit monitors/alarms ONLY for CO.

A CO alarm does not replace a smoke alarm. Each alarm warns ONLY about the danger for which it was designed.

No, this is separate. However, they do sell ones that are smoke detectors AND carbon monoxide detectors, Walmart has them too.

NO. You can have enough CO in the air to kill you without noticeable smoke so this serves a different alarm purpose.

Other combo models do both jobs but his one is just CO.

2AA batteries included per the FirstAlert website. So I assume they are here as well, but that is only an assumption.

Yes, it comes ready-to-go. You just pull out a tab to actuivate the sealed battery, and attach to your ceiling.

No, it is battery operated and mounts to the wall. I love mine. Peace of mind.

No. The ones that are plug-in with battery backup always emphasize that in their descriptions.

Is this a plug-in model besides a wall mount?

lasted six years then dead. five chirps says Im over it

Dead after six years

This item replaced one I had for 10 years and it only changed slightly.  It is on my wall and working fine.

Good product

The carbon monoxide detector came timely and of good quality. The directions were easy to follow and full informational to save and use as needed.  I liked that it had a battery with it.

good review

Nice alart, and easy to mount. Smooth battery installation and test

Great Alarm

Great to have and hope it's not needed

Purchased this to replace my existing one that was 7 years old.  They changed the location of the rear mounting holes, but it is great other than that!

First Alert CO400

Price was fair, it does what I need, I hope. I can't really tell if it is working. I would buy it again! [This review was collected as part of a promotion.]
