After having to repeatedly turn our mains power off and on, the remote keypad for the burglar alarm (that isn't set) began to emit a continuous, high pitched, annoying whine. Entering the code makes no difference; there is a red light on, on it; the wired in unit in the loft has no lights on at all.
Any ideas?
Primarily we want to stop the noise!
Thanks.
