The odds are the battery needs to be replaced. My system does this when the battery needs to be replaced. The system also beeps when the main power goes off,, or the connection to the system is terminated,

Thanks for the thoughts. It was a CO2 detector, not a radon detector
-- my bad -- that was doing the chirping, due to a low battery.
Just to make my life a bit more miserable, I unplugged the alarm system
transformer when I was trying to diagnose the problem; of course, that
did nothing to affect the chirping but did make my alarm system keypad
go into overdrive. The next night at 2 it started beeping
intermittantly, just enough to drive me crazy. I eventually went down
and reinstalled the transformer; that solved that problem.
