Honeywell accenta FAULT

[Chrishands]

Hi, i have an accenta Gen4 with LCD keypad.
came home today to a fault.

when i try to restore the fault the alarm starts going off straight away?

The screen doesnt show an error message it just shows the following:

1 2 3 4 5 6 7 8 TP
0 0 0 0 0 0 0 0 F0


any ideas please?
