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.
Asked by: PJP422
Correction - 3 1/8" is correct. Sorry.

I only have 1 co detector to install but I am hesitant about picking a location in my 2 story stand-alone. Where is best

I am 31 female and live with 4 year old son. 3 bedrooms and bathroom on 2nd floor and living rm, dining rm, kitchen on 1st floor. I have a full unfinished basement as well. I was told to install at bottom of basement stairs but im not sure after reading the manual.
Asked by: Adk1103
Hello ADK1103, If you would be able to hear the detector if it went off, then bottom of stairs is acceptable. Thank you for choosing Kidde.

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
This is only for carbon monoxide, so you would install this and not remove your smoke detectors. Smoke detectors are for fire only. Some styles of smoke detectors also include the co detector, but I have not had good luck with that type.

Do i have to push the test/reset button or will it beep automatically if it detects carbon monoxide?

Asked by: Justin
Hello JUstin, The unit will sound continuously if it is reading carbon monoxide . The unit will have to be exposed 1-4 hours before alarming at 70 PPM. Thank you for choosing Kidde.

Code One Battery Operated Carbon Monoxide Alarm is rated 4.5 out of 5 by 293.
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.

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.

The molded information needed by owner (and installers) requires good eyesight and better than average lighting, both of which are often lacking in the residences of the poor whom we serve. I don't know of a manufacturer that uses a different method of signage on their product so I'll continue purchasing these. Oh, the price was right! Volunteer with Rebuilding Together
