An anti-passback rule can be made stronger by setting the Zonal Anti-passback (‘Entry/Exit Control’).
If this parameter is set for an access group the S2000-2 controller takes into account all passages of
key owners assigned to the access group to all the access zones programmed within the system. If
an access is requested at one of the controller readers then the anti-passback rule requires that the
last passage for this key owner was that to the zone which is requested to exit from, that is at the an-
other reader of this S2000-2 controller.
Thus, for example, if the controller is located on the bound between Zone 1 and Zone 2 and entering
the Zone 2 is registered followed by entering the Zone 3 (access to which is controlled by another
device of the system), an attempt to pass via the access point located between the Zone 1 and
Zone 2 will lead to the following:
−
If the Zonal Anti-passback parameter is set, the anti-passback rule will be violated regardless of
the passage direction, because the last accessed zone differs from Zone 1 and Zone 2 , and
user presence in one of these zones is considered to be incorrect
−
If the Zonal Anti-passback parameter is not set, the anti-passback rule will not be violated by the
attempt to enter the Zone 1 and will be violated by the attempt to enter the Zone 2 , because the
controller considers the user to be located in the Zone 2 (passage to the Zone 3 was ignored by
the controller).
The Zonal Anti-passback parameter is taken into account only if one of the anti-passback modes
(hard, timed or soft) is used. If the Zonal Anti-passback is meaningless.
In order to prevent the possibility of simultaneous access of several persons by means of sequential
presenting of the same identifier at closely located readers (for example, opening several adjacent
turnstiles to pass) after the access is granted until the actual passage is detected, short anti-passback
lockout is applied for this identifier at other reader. Namely, if the access is granted for the owner of
the key presented at one of the readers and no passage has yet been logged, any attempt to present
the same identifier on any other reader (a reader of another controller) will violate the anti-passback
rule. If the hard or timed anti-passback mode is used for the reader, the access for this identifier
owner will be denied. As soon as the actual passage is detected, the lockout is canceled. If no pas-
sage is detected (or a passage sensor is not in use), the lockout will be canceled in a minute. While
the lockout is active an access for the owner of the specified identifier is possible only through the
lane controlled by the reader where the identifier was presented for the last time or through any other
lane controlled by a reader where anti-passback rules are not applied for this identifier.
This must be taken into account while designing the access control system at the installation. If some
access points exist not far from the access point where anti-passback rules are applied (may be
reached in one-minute walk), the other points have to be equipped with passage sensors (to generate
a passing event after access granting) or the zone number 65535 has to be assigned for these ac-
cess points (access granting and passage to this zone are not transferred to other system devices
and do not cause lockout of other readers).
