If the areas on which you want to apply the antipassback restrictions are controlled by multiple Synergis™ units, you must enable global antipassback on the Access Manager roles.
What you should know
NOTE: When global antipassback is
enabled, the presence of a cardholder in an area is forgotten after seven
days if no entry or exit from this area is reported for that cardholder
during that period. This means that cardholders can re-enter an area that
they never left, or leave an area they never entered, without triggering
a passback event if no movement was registered for these cardholders on
that area for seven days. This applies even if the Presence
timeout is set to infinite (=0).
When strict and
hard antipassback is applied to an area without global antipassback, a
cardholder who entered the area through one door cannot leave the area through another
door if both doors are not controlled by the same unit. Also, the same cardholder who
entered the area through one door, can re-enter the area through a different door if the
two doors are not controlled by the same unit. With global antipassback enabled, these
two violations can be prevented.
IMPORTANT:
Global antipassback only works on areas that
are entirely controlled by Synergis units.
All units controlling the same area must be managed by the same Access
Manager.
Tip: If you need to switch your units between Access
Manager roles to meet the global antipassback requirements, use the Move unit
tool.
