Something started beeping yesterday. Spaced a minute or so apart. First I
thought it was a radio malfunctioning. but after turning things on and
off
it wasn't. Nothing else plugged in and turned on in the room. Finally
after
about a half hour discovered it was the smoke alarm low battery
warning. No
spare 9V batteries, have to buy a few today.





Fifteen or 20 years mine did that at 3 am and I just could not go back
to sleep..so I changed the battery, hopped back in bed only to hear beep
again...so changed the battery in my 2nd detector , went back to bed
and doggone it...the beep was still there.

Turned out it was my pager damn it!



That is part of the problem today. Other things beep.
My smoke detectors and CO detector were old and in same hallway upstairs
and downstairs it took a while to find the one beeping.
I replaced all with new with long life batteries and have had no
problems like others here.
