When a user enters the duress code in stead of the normal user code, the
DU-OUT terminal [f] is switched to ground and can be used to trigger a

User code limitations
•
To avoid overlapping of valid user codes and duress codes, and since the
duress code is based on the first digit of the user codes, it is not allowed
to have user codes that only differ by +2 or -2 in the first digit.
Example: if a user code 56789 exists in the system, user codes 36789
and 76789 will be refused by the system when trying to set them as
other user codes.
