Scantronic 9651 aux dc fail?

I have just amended the programmed zones so that the kitchen sensor is not set when setting the system using B program.

I managed to sort that out ok but when I went to test afterwards, the alarm sounded I entered the access code to stop the alarm and now I am left with a aux dc fail message.

I have tried an engineer reset but that hasn't worked.

Any ideas would be greatly appreciated.
