Global antipassback
The basis of the global antipassback is the zoned antipassback. The facility is
divided into rooms - zones of access or areas. With this division the entrance to
another area is exit from the previous one, and the passage in the area is possible
through various access points.
Antipassback control panel receives data from the access control panels and tracks
the movement of personnel from area to area . Also can be tracked the location of
the person who has multiple IDs (See Figure 5).
Figure 5.
Allocation of access areas
Initially an employee has the location "unspecified". After the first presentation ID to
a reader's location
The location "unspecified" is assigned when registering a new employee, or after the
system operator command "location reset" of person is fixed by U-Prox IC A.
With the use of global antipassback it is possible to suppress passback, using
duplicate card for infiltration (sudden appearance inside), transferring the ID to
another person, etc (See Figure 6).
