Interlogix Simon XT: Setting Installer Code to Default

In this video, Michael from Alarm Grid shows you how to set the Installer Code on an Interlogix Simon XT Security System back to its default. For reference, the default Installer Code on an Interlogix Simon XT is 4321. This is also the same default Dealer Code for the system. The only way to have both the Installer Code and the Dealer Code as the same code entry on a Simon XT is to keep them at their identical default of 4321.

Once you change one of the codes, then you can't change it back to its 4321 default as long as the other code (the Installer Code or the Dealer Code) is still set at 4321. The system will not let you manually set two (2) codes to have the same entry. The only way that this rule does not apply is if you keep both codes at their defaults and do not change them. If you do change either code, then the only way to reset them both back to 4321 is to perform a full factory reset for the system. However, it is important to note that the Dealer Code will only revert to its 4321 default after a system factory default if the Phone Lock setting is turned OFF, which is the default selection. But if Phone Lock is ON, then only the Installer Code will revert to 4321 after a factory default reset.

Keeping in the Installer Code and the Dealer Code at their 4321 default is recommended by Alarm Grid. Even if you lose one of these codes and forget them, you can always look them up later on if they are kept at their default values. Furthermore, it is not a security risk if an intruder knows one of these codes. The Installer Code and the Dealer Code cannot be used to disarm the system. If an intruder tries to disarm the system with one of these codes, then nothing will happen. They must have the Master Code or a valid user code to successfully disarm the Interlogix Simon XT Security System.
