I have bought a house with an alarm which can be silenced only by switching off the ring which also powers the sockets in the house.The occupant died and no record of the alarm code was left.Is there an easy way to disable by resetting to the factory default?I do know the installers but suspect there will be a callout fee etc.
I would be very grateful for any advice you can offer.
