Thanks to all who replied. All of you provided useful advice. It
turns out it was the carbon monoxide detector within 5 feet of the smoke
detector. A steady tone instead of a chirp every 30 seconds or so would
have made it easier to track down, but such is life. All is well that
ends well.
Thanks again.
