A friend has moved into a new house with an Accenta 8 alarm system
which was originally installed by Protec, who were taken over by
Initial then Chubb. It looks like the battery is flat as when he had
to switch the electric off, the alarm went off. I believe to change
the battery he'll need the engineer code, which Chubb won't let him
have and want to charge a silly amount to come and change it. On the
panel is written "Initial eng code".

Anyone know what the engineer code Initial used is please?

TIA, Jason
