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.

Battery Operated Carbon Monoxide Alarm is rated 4.5 out of 5 by 266.
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.

The batteries provided in the four sets of CO detectors I bought on the two occasions were all dead. I had to buy new batteries to make them work. When I complained to the counter clerk later, she said all I could do was to return them. Whew! I had already installed them high on the wall with fresh batteries and I was not going to take them down. Besides, all other sets of the same brand at the shelf probably have dead Kiddie batteries too, to my best judgment.
