Smoke Detector Phantom Beeping

I have seen postings about this issue on this forum before and am hoping someone can help.

For the past week, our hard-wired smoke detectors have had a faint beep (like you'd hear if the batteries were weak) every 45 seconds or so. It started the day after a big storm, so I am thinking that it might be related to the electrical wiring - perhaps there was a surge or a dip in power that affected the wires?

We have 10 detectors and they were new 2 years ago when we remodeled. Our contractor came out last week and replaced them all and they are still beeping.

We turned off the power to the smoke alarms, unplugged them from their wiring, took the batteries out, and there is still beeping!!! It sounds like it is coming from the ceiling between our 1st and 2nd stories. There is no possible way there is an extra smoke detector up there.

We have no carbon monoxide detectors that could be causing the beeping.

What could possibly be causing this problem?!!! Thanks for your help!!!
