Smoke alarm beeping without battery or disconnected
I have 6 smoke alarms in my home; they are all hard-wired. I have had to disconnect completely--take them out of the ceiling--two of them as they went off for no reason. I took the 9 volt battery out of either of them first. That didn't stop it. Then I pulled the alarm out of the ceiling and 'unhooked' the alarm from the plastic 'thingy' which is connected to the black, white and yellow wires. One of the alarms stopped beeping but the other one continues to beep just once in 5 to 8 minute intervals. HELP! (Please) I and my family and cat are going crazy and I can't go to work till this is fixed. Thanks!
