smoke alarms chirp when the battery gets low.

Hmmm. I will check that out. I have one sitting in the dr on the
buffet and one in the sunroom. Didn't bother to get on a ladder and
install them the proper way. That might be it. Thanks! It's chirping
now. I just took two batteries out. There are more in boxes in the
spare room, don't know where exactly I put them.

I'll try to get back to you on this.
