Hi Folks
Perhaps one you worldly types can succeed where our local sparky is flummoxed.
Our smoke alarm has been beeping every thirty seconds. We have two, both hard-wired to the electric and also with a 9v back up battery in each detector. We replaced the 9vs in both this morning and vacuumed the detectors. No joy. We've since disconnected both detectors from the wires in the ceiling and cut the mains power. There's still a beeping noise coming from the area in the downstairs ceiling from where the detector was (there's no noise from the upstairs unit).
Anyone shed any light? Is there another possible power source I'm missing? Like I said, mains is off, units disconnected and 9v batteries removed. Are we looking at knocking out the ceiling here?!
