This was at an inspection this past Saturday. The house was built in 1974.
These were in most rooms. There were wires going to the unit. It was low voltage wires.

My WAG is some kind of heat/fire sensor. Watching.

I think Dave is correct on this one. Dictograph heat sensor?

So the cool thing about those Dictograph sensors, is they were attached to one of these. It’s probably long gone, but still would be an awesome thing to put up for that whole retro vibe.
