− None (the S2000-2 controller is not checking any anti-passback rule)
− Hard
− Timed
− Soft
The Hard Anti-passback rule requires to prohibit a second passage to a zone up to the moment of
logging the exit from it. If someone attempts to violate the rule, access is denied and the ACCESS
DENIED message is generated with the Anti-passback rule violation attribute.
The Soft Anti-passback rule does not prohibit a second passage but in case of its violation the AC-
CESS GRANTED and PASSAGE messages are generated with the Anti-passback rule violation at-
tribute.
The Timed Anti-passback rule uses an additional Anti-passback Lockout Reriod parameter. During
this time period since passing to an access zone the S2000-2 controller is operating as for Hard Anti-
passback rule (repeated access requests to the zone without exiting it are rejected and ACCESS
DENIED messages are generated). After expiration of the specified time the S2000-2 controller is
operating as for Soft Anti-passback rule (second access is granted, but the ACCESS GRANTED and
PASSAGE messages are generated with the Anti-passback rule violation attribute).
If the S2000-2 controller operates as a part of an Orion system, it checks anti-passback rules taking
into account all passages to the access zone registered by other controllers of the system (the Global
anti-passback rule is implemented). So, if an access zone has several access points (for example,
several gate houses to enter/exit from the company premises or several turnstiles operating in paral-
lel) equipped with S2000 controllers, entering the zone via one of the access points will lock the ac-
cess to the zone through other access points and unlock the access from this zone. Vice versa, leav-
ing the zone via one of the access points will lock exit from the zone and unlock entry to it (of course,
if the anti-passback rule checking is programmed for the key presented).
Anti-passback rules will operate properly at an access point between two zones only if two following
requirements are met:
− Authorized passing from one zone to another is only possible via the access points controlled
by S2000-2 controllers
− Each the access point has to be equipped with two readers providing identification both for entry
and for exit as well as a passage sensors.
For the Global anti-passback mode to operate properly all readers controlling entry to a zone must be
programmed with the same Access zone number. Checking anti-passback rules each S2000-2 con-
troller takes into account a passage registered by any other S2000-2 controller of the Orion system if
the passage is relevant to the two access zones which are assigned with the S2000-2 in question.
Passages relevant to zones not assigned with the S2000-2 controller are ignored.
