Beeping from attic
We recently moved into a used house and a few months ago noticed a high pitched beeping sound which seemed to originate from a particular location of the ceiling in the hallway. This beeping sound continued for several hours, until finally it started to gradually become quieter and quieter, until after an additional hour or two the sound faded away... as if a battery had been depleted.
We haven't yet entered the attic, as the barely human-sized access hole in our closet isn't very inviting.
Can anyone offer any theories as to what the source of sound could have been? ...how about advice on climbing into the attic?

Thank you!
