Local APB Setup - Mercury or Mercury Powered Con-
trollers
When using the Mercury hardware or the Mercury Powered NXT controllers the setup
principle is very much the same as when using PXLs, but there are more settings that
can be defined for this feature.
1. Highlight the reader on the hardware tree and in the properties, scroll down to the
Anti-Passback section.
2. There are several APB modes available when using these controller types:
l
Soft Anti-Passback - When using Soft APB users who violate the APB rules are
still permitted access, but an event is generated which could then be used as a sys-
tem alert, for example to generate a sound at the PC which will be brought to the
attention of a security guard or someone else who will be responsible for man-
aging the system, so that corrective action can be taken to ensure cards are used
in the proper sequence in future.
l
Hard Anti-Passback - A cardholder will be denied access if the card is presented
'out-of-sequence'. If the feature is setup to operate between two readers then no
access will be allowed through the 'entrance reader' until access has first been
granted through the 'exit reader'.
l
Timed - Reader Based - This settings is useful when there is just one reader, for
example an exit button to exit. If there is just an entrance reader and no exit reader,
or perhaps on a uni-directional turnstile. This setting prevents a cardholder from
'passing their card back' and the card can only be used at the same reader again
