Concept 6 alarm continuous whine!

[miljee]

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.

When was the last time the battery back up was replaced ?
Battery should be replaced every 5 years or before if required
You could have a faulty battery and panel telling you have a FAULT ?

It's probably burnt out the charging resistor !

A Concept 6?! Wow, that's come a long way then! Perhaps disconnecting the control panel from the battery (which is probably dead) and taking the fuse out of the FCU will silence the inside alarm part... then again the bell box outside will probably start ringing if the battery's good in there as well. Judging from the fact that it's a Concept 6, I doubt the battery in the bell box is working either.
