Do smoke and carbon Monoxide detectors always give their low battery alerts in the dead of the night?
It took us 10-15 minutes to find the detector that was beeping last night. It would beep and then it emitted a voice message "low battery warning". At first I thought it was my pager. Nope, I followed it upstairs. I turned on a light in our bedroom. That made Hubby get up are help find it. He was able to follow their noice to DS9's room where he dounf the detector (I did not realize there was one there.)
