We have just installed the Yale Premium Home Alarm and thought we had cracked it until we forgot to replace the rubber stopper on the control panel, which we have now mounted on the wall. It is showing a tamper fault which means we cannot set the alarm. I can't find any information in the instructions as to how you cancel/reset the fault without restoring to factory settings which we don't want to do. Anyone got a simple solution for us? Thanks BrenthamFrank
