Answers

This KIDDE unit will be compatible with your system. The new unit comes with a new mounting ring and wiring harness (connector plug). If you do not have "Do it yourself" experience, a local handy man would be able to change out this unit in less than 15 minutes. You can watch a YouTube video on how to change out the unit so you can do it yourself.

Hello klb, Thanks for reaching out. If you disconnect one at a time from the hardwire and place the unit in your car or garage, and go back to the location with the wires hanging, are you still hearing the chirp? If yes, there is another unit chirping. It will be a process of elimination, so remove the units from the hardwire and isolate them until all of the chirping stops. If you are still hearing a chirp, then it may be a free standing carbon monoxide detector plugged into an outlet or a unit that was put in a closet or drawer with the battery still inside.

As far as I know they should all be compatible with each other regardless of the model number. Some will wear out sooner then others so I just replace it with the current model.

Can I mount Model 21010408-N units (as replacements) on brackets from Model KN-COSM-1B units which have expired?

Hello. Yes. They should have the same mounting bracket and the same wiring harness plug.

What kind of batteries to use to replace old ones?

Answers

This has a 10-year battery. It is not designed to be replaced. At the 10-year mark you need to replace the unit as that is the lifespan of smoke detector.

The Kidde 10-Year Worry Free Hardwire smoke and CO2 Detector fit in the same place as my old "change the battery every year" Kidde detectors. This made installation easy. Not the base plate was different. They arrived well packaged and on time. All parts were present. I will only know if they are excellent if I have a fire! Hope I won't be reporting back about that.

The product is excellent. I purchased 5. However, the store stocking/restocking process needs a lot of work. After two trips to the store for a missing part (electrical pigtail connection) on the third trip I had to open five boxes to find one that had the missing part.
