How to disconnect a house alarm DIY?
There's a unit in the house we've moved into, but it's beyond useless as it just goes off whenever we put it on. Can't be bothered with repairing it right now, so can I do something to disconnect it?
Expert Trade Answers
"There should be a fused spur. Take out the fuse and disconnect the battery inside the panel. The siren on the outside of the house will sound and the batteries will need to be taken out of this too. Do not try and disconnect any mains electric."

"Usual steps involve isolating the power and correctly disconnecting the backup battery within the control panel,but this should be done with care to avoid alarms or faults."
