Global anti-passback
With global anti-passback, the whole site is divided into “zones”, each
zone having a different name. Each door between two zones, for
example zone A and zone B, is controlled by two access points; one
for entry to zone A and exit from zone B; the other for entry to zone B
and exit from zone A.
Wiring
The wiring for each door is exactly the same as for local anti-
passback on the previous page.
Configuring
1. Door monitoring should be Enabled on both Readers (select
the check box labelled Enable Door Contact Monitoring on
the Monitoring Actions page in the access point records).
2. Door Forced and Door Open should be Enabled on one reader
and Disabled on the other reader (it doesn’t matter which way
round). (The check boxes are Door Forced Alarm and Door
Open Alarm on the Monitoring Actions page in the access
point records.)
3. Also on the Monitoring Actions page in the access point
records, the Reader giving entry to the zone at this access
point should have the name of the reader exiting the zone at
this access point in its Shunt field.
4. Global anti-passback must be Enabled on the Anti-Passback
page in the System Administration program.
5. Each zone must have its entry access points and exit access
points configured in the Zone records in the Access
Configuration program.
Refer to the Access Control System Software Handbook HB02/100 for
more details of configuring the Software for anti-passback.
