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?
