After switching off the main consumer unit in my house a few times to do some electrical work my scantronic 9452 is now not working. Is there a way of reactivating it so it recognises the alarm codes when we want to set it before we leave the house.

9452 is a good panel, although it did have a few tamper problems it should last for years.

Sounds like a dead battery, post your post code on here and someone will be able to pop out and service the system.

If you are lucky the charging system may not be damaged by the old battery.

If you have an external siren that will also require servicing/replacing as it should have self activated when all power has been removed (obviously the back up battery would take over in he panel and prevent this from happening if it was working)

Hope this helps.
