In the event that you need to change your user code or add new codes to your system all you need to do is phone us and if you are one of our existing customers then we should be able to dial into your alarm system remotely, via our security computer, and make the required changes for you. Please be aware that in most circumstances a small fee will apply. Most of the time you should be able to make these changes yourself if you have the correct user manual. If you are not an existing customer we are still able to help you however this does mean that we will have to make a visit to your premises in order make the required changes.
