Woke up this morning to a chirping beep every 55-60 seconds. Smoke alarm battery, right? Well I have three hard wired CO/smoke and two smoke detectors. Hard to tell which one was chirping. Took our best guess and started to replace batteries. After replacing them all, the chirping continued. Checked all for proper orientation and closed them back up. Chirping continued. Then one by one, I removed from the ceiling and sequestered them. All batteries checked good. Beeping continued and appeared to be from my family room ceiling. Surely not there!! After several rounds of installing and removing, I called the fire dept. They came out and in about 15-20 minutes, they located a battery powered CO detector on top of a shelf. No idea where that came from. i felt stupid, but happy. Great bunch of guys.
