Hi
Just moved house, was unsure of code on my scantronic 9448+ to cut a long story short we tried the code we thought and attempted to reset to a memorable number. The alarms went off and could not stop them. Had to disconnect the electricity to it, removed battery on the mother board (cannot get up to external box as it's too high). Alarms have gone off now... can we attempt to set it back up and reset the code again? Thanks in advance. Mel

How are they obliged if they did not know the code in the first place?
Has happened.

OP you can get a pro in or use Google and look for a manual and follow it to the letter.

so you don't know the code for it,

you cannot change the user code without first entering existing code,.
Contact the previous owner, or agent,they are legally obliged to give you the information,especially if the system hasn't been powered down.
If you power the system back up without the user or engineering code,you will not be able to silence or reset the tampers.
Its a great panel and well worth getting a pro in to sort and service it.
Hopefully it should give you many more trouble free years.
