The only beep-beeping I've come across has been laptop PCs left on standby
warning that their batteries are about to run down. I think some mobile
phones and VHF hand-helds might do that too.

It's very hard to determine where an infrequent beeping sound is coming
from. My wife and I were once woken in the night and spent about an hour
searching for the source of a regular but infrequent beep, which turned out
to be the (mains powered) smoke alarm telling us that the backup batteries
(which I didn't even know existed, and which were 6 years old) were about to
die.
