Good unit but life is 7 years from first turn on. It will automatically begin to chirp every 30 seconds till power removed or unit replaced.
Rated 2 out of 5 by musicjon overly sensitive detector
I bought this smoke detector about 2 years ago and it is already malfunctioning. It goes off whenever there is any heat or smoke when cooking. It will only shut off if I remove it from the ceiling, and then sometimes when I put it back, it goes right back to sounding off way after I have finished cooking. I was cleaning the bathroom once with lysol and the alarm went off. It is way too sensitive and difficult to shut off. I will never buy this product again.

I needed something to come up to code by having CO Monitors added to an already existing Kidde six unit Smoke Alarm network running through the house. I went online to Kidde's website and requested which unit would would work with my existing system's Smoke Detectors. They emailed back that this model would work. I bought two in order to meet code and have one at each end of the house. The connector matched exactly. The only thing I had to do was remove the old mounting base and install the new one (two screws). Comes with the 9 volt battery installed also.
