@ 2" ceiling plate?
Anyone know what this thing on the breakfast area ceiling is - it's about two inches in diameter and is in a few other rooms too.

Many newer homes have fire sprinkler heads covered by plastic caps. They pop off when the system activates.

Re: @ 2" ceiling plate?
I've seen something like that without the holes in it. One in the kitchen, one in the living room. They were the capped off lift point for a manufactured building. Look on the outside roof above the cap to find out for sure. There will be a raised nipple where the cable passed through. It should be capped off; if it's not... it will leak. (I'm aware another forum member identified it as a glass breakage sensor... it probably is... just putting in my two cents worth).
