So I have 4 hard wired 9 volt battery smoke detectors in my house. One of them was chirping and I decided to replace all 4 batteries. The first one was changed with no issues, and I pushed the button to test and it was fine. The second one went haywire. When I replaced the battery and pushed the test button it then triggered all 4 detectors into full alarm mode.

One detector was unreachable, so I started removing the batteries from the other 3. One by one removed and the alarm would not cease. I couldn't reach the 4th, so I decided to unplug the hard wire from the ones that had the batteries removed. When I unplugged the first one nothing happened and the alarm kept going. Then I unplugged the second one and that stopped the alarm, but it didn't really stop it, it mostly sounded like it was powering down. I unplugged the third one as well just to be safe.

Today I got a ladder to reach the 4th detector. That one is still hard wired. I replaced the battery in that one and had no issues or alarms. Then I took the 2nd detector and put a new battery in, but when I pushed the battery case back into the detector it triggered the alarm, and it wasn't even hard wired....

I need help...I currently have 1 detector with a new battery that is hard wired. Then I have 3 detectors that are unplugged, and have no batteries in them currently. I'm trying to get them all back active with new batteries and plugged in. Please help me...
