The house should have been painted up to the electrical box

so whether it is 4 or 6 inches in diameter no painting should be required. Four inches would be smallest you would see them because that is the standard electrical box dimension. '

Also, be careful you are not comparing apples and oranges. All smoke detectors I have seen have a plastic plate that attaches to the electrical box and the smoke detector hooks to that, could be your looking at the plate on one 4" and the actual smoke detector 6" on a different one.

I bought AA battery powered ones after the 10 year battery one died soon -- MEHOKIE 01/04/2018 6:44PM

Guessing most 10 yr ones won’t last that long -- DaveVT 01/04/2018 3:19PM

We just took down most of our wired ones -- daisyWV 01/04/2018 3:15PM

Mine have both. Battery for detector, and wire to link them. If one -- 48zip 01/04/2018 3:21PM

And that's the problem when you have 8 of them. Which one is it? -- AZHokie59 01/04/2018 4:49PM

Do they not connect to a wired circuit? Also, I've always wondered.... -- 48zip 01/04/2018 1:51PM

The mounts are different, but I think I can cover the holes with the new -- AZHokie59 01/04/2018 3:03PM

You need to get hardwired ones if that is what you had** -- DaveVT 01/04/2018 3:20PM

All should cover a standard electrical box. ** -- thankbud 01/04/2018 2:29PM

But if the diameter of the new one is smaller than the old one..... -- 48zip 01/04/2018 3:17PM

Correct. Detector twists onto a plate. Bad description by me. -- 48zip 01/04/2018 3:45PM

Certainly possible, bad paint job them :-) -- HokieForever 01/04/2018 3:48PM

Possibly, but won't know that until you have it in hand. I have never done -- thankbud 01/04/2018 3:20PM

Yeah, I was hoping for a simple solution. Don't think there is one. ** -- 48zip 01/04/2018 3:22PM

Right, only problem here is these mounts are made to attach to a wall or -- AZHokie59 01/04/2018 3:06PM

Been a little while, but I've seen them configured to attach 2 ways. One -- thankbud 01/04/2018 3:16PM
