Customer Questions & Answers

What is the measurement of the width between the screws (for mounting on the wall)...is it 2.375" ?

I had a Kidde Model # KN-COB-B P/N: 9CO5 mounted already on the wall and it recently errored and cannot be reset so, I am trying to replace with a model that I can just hang up on the wall, without having to move the screws. Thanks for helping.

I currently have smoke detectors, home inspection requires carbon monoxide detector. Do I remove my regular one, and this one works for smoke, and carbon monoxide?
Asked by: carlos
Hello Carlos. No, this alarm does not detect smoke. If your current smoke alarms are battery only, you will want Model # 21027454 Internet #205844406. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

Battery Operated Carbon Monoxide Alarm is rated 4.5 out of 5 by 276.
Rated 3 out of 5 by from Simple CO alarm for residential use We have ordered these alarm devices because our original ones died right at 10 year. Just as the label says. These devices are easy to install and they are very simple. The reason for3 stars is they don't fit tight on the screws, they kind of hang from our ceilings.

This is the lowest cost Carbon Monoxide Alarm that Home Depot carries and have installed several in my home and rental properties that I own. The installation is very straight forward and units seem to work well.
