AntIPASSBACK
Antipassback is a feature designed to prevent or discourage an authorized cardholder from passing their card back
to an unauthorized person who wishes to re-use the same card to obtain access. The most common application for
Antipassback is Parking. Antipassback is not generally practical for use by office or factory personnel, unless turnstiles
are in use. When Antipassback is enabled, the 28SA-Plus will temporarily void a card after the first use, so that any
person attempting to reuse the same card in the same reader will be denied access. This temporary void status is
stored in memory in the 28SA-Plus. Different types of Antipassback use different methods to void and reset the card.
The 28SA-Plus offers two types of Antipassback: Real and Timed.
REAL ANTIPASSBACK requires the use of a 28SA-Plus and a Remote Reader. The main reader (the 28SA-Plus) can be
designated as an In reader or an Out reader; the Remote reader automatically takes the opposite type. In memory,
each cardholder has In, Out, or Neutral Antipassback status, which is determined by the antipassback type of the
reader where the card was last used The cardholder must have Out status to use an In reader and vice-versa. As
long as the IN and OUT readers are used in alternating sequence, there will be no restriction; if a card is used at an IN
reader twice in a row, or at an OUT reader twice in a row, the second access attempt is denied.
Real Antipassback only applies at one set of Primary / Remote readers. Even if multiple readers are connected to a
PC using Smart Switches and SA-NETTM software, other 28SA Units at the same site will be unaware of the cardholder’s
IN/OUT status change.
tIMed AntIPASSBACK
sets the card to Void status for a user-defined time period. Once the time period expires, the card can be re-used in
the reader. For every card use, a comparison is made in transaction history to that card’s previous use to see if the
time period has elapsed. Timed antipassback only applies at a single reader; other 28SA-Plus units at the same site will
not be able to make a time comparison. Note that if a Remote Reader is connected to the 28SA-Plus, once a given
card is used, it cannot be reused at either the remote or main reader until the time period has expired.
ConFIGUrInG reAL AntIPASSBACK
To configure a 28SA-Plus and Remote Reader for Real Antipassback, you must first set the 28SA-Plus (Primary Reader)
as either an IN or OUT reader. To set reader IN/OUT status, choose 5 (Configuration Menu), select 5 (Primary Reader),
then select N (None), I (In), O (Out), or press ESC to exit. The Remote Reader automatically takes the opposite status.
Real Antipassback cannot be set up with the program deck.
To be affected by Real Antipassback, cards must be assigned to a Time Zone with Real Anti-Passback enabled. See
Page 13 for information on how to assign a card to a Time Zone, and see Page 32 for information on how to set Real
Anti-Passback in a Time Zone.
The DAILY APB FORGIVE HOUR feature is also available on the Configuration Menu. During the course of the day,
cardholders’ Antipassback (APB) status may get out of synchronization when entering or exiting without using a card
(due to disabled parking gates, exiting after-hours, etc.) DAILY APB FORGIVE will set all cards to a Neutral status, so
that all cards will work the first time they are used on the following day, regardless of their Antipassback status at the
end of the previous day. After the first usage, the card’s Real Antipassback status will change normally.

If Timed Antipassback is selected, a card used for entry is made temporarily void for a user-definable amount of
waiting time. The antipassback waiting time may be set to any number of minutes from 1 to 30. However, the actual
waiting time will fluctuate between the time set and the time set plus one minute. Thus, if the antipassback time is
set to 5 minutes, users will have to wait a minimum of 5 minutes and a maximum of 6 minutes before reentry will be
allowed. Setting the antipassback waiting time to 0 will disable the Timed Antipassback feature and reentry will be
allowed immediately.

To set the Antipassback Waiting Time using the Program Deck, place on the TOUCH CARD® reader plate the
sequence of cards representing the number of minutes of the minimum waiting period (1 to 30), then place the “*”
card on the TOUCH CARD® reader place and remove it, then place the “SET TIMER” card on the TOUCH CARD®
reader plate and remove it.
Example: Set antipassback waiting time to 3 minutes.
Place the “3” card on the TOUCH CARD® reader plate, remove it, and place the “*” on the TOUCH CARD® reader
plate, remove it, and place the “SET TIMER” card on the TOUCH CARD® reader plate, and remove it.
