Antipassback Zones

While antipassback can be employed on a system-wide basis, it often is used within an
overall access control system for specific zones, such as server rooms, data storage
facilities, and other high-security areas.
NOTE:
If an individual enters a door configured within an Antipassback zone

without showing his credential, he will not be able to exit that zone
when he presents his credential. Similarly, individuals who exit a door
in an Antipassback zone without presenting a credential will not be
allowed to reenter until the Antipassback Reset Interval has elapsed.
Devices may have both a Primary and Alternate zone:
The Primary Zone is the location of the primary (or only) reader associated with a device.
Alternate Zones indicate the location of a secondary (or alternate) reader that is applied to
Antipassback configurations, if one is configured for that device.
