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 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
No need to remove a combination detector as long as it is working.

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 purchased this unit, but for some reason it did not come with an instruction manual. Why is there a flashing green light ? Thank you
Asked by: daka
Go to the Kidde website and search on model KN-COB-LP2. Select the documents tab and download the user manual. The green light should flash once every 60 seconds indicating normal operation.

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.

This is without a doubt the most cost effective, brand name, battery operated carbon monoxide detector you will find. Ironically it is almost identical to its sibling the "Kidde, worry free, ten year lithium battery model". (I (I can't comment of the effectiveness of the unit for obvious reasons.) This unit is priced at half as much as its, sibling but appears to be identical with the exception of the case. Both are made by Kidde and have the same lifespan and warranty. It comes with mounting hardware and mounting instructions. As detectors go this one should work just as well as units costing 2 or 3 times more. It's basic protection which is all I was seeking.

Rated 3 out of 5 by from Lasted 6 years This is the unit I had until recently in the apartment I rent. In the year I've lived here I've had to change the battery 3 times. Today it started beeping a lot in a random pattern and I couldn't tell it was detecting anything or if it was just a malfunction of the detector. It was flashing at the "alarm - move to fresh air side" but with no stable pattern. So I bought 2 new detectors at HD and neither them are detecting any CO, leading me to believe this old unit was malfunctioning. The new ones (different model, same brand) have a screen to indicate the CO level and to indicate if there is an emergency or a just a problem with the device. When I removed the batteries from this malfunctioning unit i found a sticker that said it was manufactured in 2011 (it's now 2017) so it lasted 6 years.
