How to enable global Anti-passback in the U-PROX IP system

Here’s what Antipassback.pdf specifies for configuring anti-passback in U-PROX:

• Entry-perimeter enforcement:
  If a user has not passed through the defined entry perimeter, any subsequent attempt to enter inner zones will be denied. drive.google.com
• Global Anti-Passback:
  The “Global” anti-passback mode must be enabled on every door in the system to ensure a person cannot re-enter via any other door without properly exiting. drive.google.com

Make sure you have:

1. Defined a perimeter zone in the Web client under Installer → Anti-Passback.
2. Enabled Global Anti-Passback on all doors in that zone.
3. Assigned the correct controller roles (IP400 vs. IC A) and uploaded the configuration to each device.

Let me know if you need the exact menu paths or a step-by-step guide!

Of the listed doors, the two at the top serve as entry points to the premises (perimeter control), while the rest are internal doors.

• If entry through the first two doors is not recorded, the system will deny both exit from the premises and any passage through the internal doors—this is enforced by the global anti-passback logic.
• If entry through the controlled perimeter (the first two doors) is correctly recorded, the user may move freely within the premises, including passing through the internal doors.
