After fitting an additional door sensor I couldn't set my alarm (accenta 8 mini) I removed the new wiring (and refitted the zone link wire) but the alarm still won't set - I input the set code and get the normal setting sound immediately followed by 4 quick beeps which I think means a general fault on all four zones. I've done a complete factory reset and cleared the NVM before setting the system up from scratch. Before I remove all the wiring and start again are there any suggestions out there? Thanks
