For a successful service and maintenance of most alarm systems, the intruder alarm engineers need both user code and master code (engineer code) for your alarm. If you do not know your codes, to complete a service and make changes to your alarm, we may have to reset and reprogram your alarm. Add this to your intruder alarm service order package if you don’t know your alarm codes.
