No, this is simply a smoke alarm that works off ionization of the smoke particles.

when the unit is temporarily removed from the ceiling what happens? Will it chirp? or just not work until it is replaced on the ceiling.
Asked by: inquisitiveneighbor
Hello Inquisitiveneighbor, The unit doesn't have to be on the mount to work. Once the battery is activated, it will continue to work.

Is this detector suitable to use in a kitchen
Asked by: misty
Not ideal. It is super-sensitive not only to actual smoke, but also heat, so it goes off unnecessarily often when something gets even slightly overcooked. It would probably be better to mount it some distance from the oven/stove and even the toaster if you like your bread well browned.

Kidde Code One 10-Year Battery Smoke Detector with Ionization Sensor (36-Pack) is rated 4.4 out of 5 by 349.

We need a closed one in an ADU, so the battery cannot be accessed. However, the first one we bought started beeping randomly for no reason. Literally, the only way we could get it to stop was to cut the wires to the battery.

I bought one of these today after a frustrating experience with a similar First Alert unit. I'll never buy another First Alert. I tried - and failed - to install the First Alert. On a 1 to 10 scale, when it comes to being "mechanically-inclined", I'm a 9.5. 1. The Kidde has instructions you can read. The First Alert instruction text is soooo small that it would make an attorney jealous. I could not read it, and hauling out a magnifying glass was not a good solution when trying to find the actual instructions buried somewhere in their version of War & Peace. I would advise Kidde on thing though - don't mix languages. Put the languages in separate documents. 2. The First Alert was impossible to open and install the 9V battery. I could not do it, and I couldn't find instructions on how to do it. It was like a Chinese finger puzzle. Installing the 9V battery in the Kidde is idiot-proof. 3. The First Alert will be returned to Lowes tomorrow. The Kidde is now installed.

This was $15 versus the same one branded Kidde, in bold type, but cost $25. Mine was purchased to replace a Kidde brand 10 year model that did not last that long, it lasted only 4 years before going off with a fire warning that did not exist. I'm a little disappointed in the life of the one but the other one purchased at the same time is still functioning properly. So I say "things happen".

Have never had this brand before but I figure that how much difference is there in different smoke detectors. All I needed was a basic model and this fills the bill. I am curious about the 10 year life span with the built-in battery. If it makes it just half that long it will be cheaper that the cost of replacement batteries.

The box had both the narrow and wide spread mounting holes and neither worked. These also have 10 year lithium batteries. When the battery goes dead, you buy a new smoke detector.
