I know most homes and flats have smoke detectors (or should have) but I was wondering around what time did the smoke detectors for homes first come into play?
I mean the battery powered ones you buy and stick up in the hall for your home?
I would think it would be the late 70s. I don’t recall every seeing anyone have one before then.
I don’t remember our house having them until the mid-70s and I remember them being fairly pricey.
