I have four smoke alarms/carbon monoxide detectors and remember setting up three; the fourth one, I don't remember what I did with it. I don't remember if it was stored away with batteries in it or not. Now, I'm hearing that beep beep sound that emanates from the alarm when the batteries have expired.
The batteries have been removed from the three alarms and I am still hearing that annoying driving-me-crazy beep beep. My question is - if batteries were in the misplaced alarm, will it eventually stop beeping? I just cannot find it, and each room I go into the beep sound as thought it's in said room. This is driving me insane, please help!!!!
If you are ever tempted to get one of those "whistle / clap for your keys" keyrings, then remember this experience. They go off for everything - we had to throw it away - a long way away!
