4.1 Anti-Passback Mode
There are three operating modes: Soft Mode , Hard Mode and Time Reset.
Hard Mode: This mode enforces the anti-passback function. Consider the case of a
Cardholder who enters the facility (card read by the entry reader). If the cardholder
exits together with other staff members (without registering) the P908 will have only his
entry record. When the cardholder tries to enter the facility again, P908 will find no
previous exit record and therefore, entry will be denied.
Soft Mode: The anti-passback function limits to monitoring and alarm reporting. In the
soft mode, users are still allowed entry with the event reported.
Time Reset: The anti-pass back time reset mode allow flexible antipass back rule to be
apply based individual operation needs. When antipass violation occurs cardholder will
be denied entry for a preset period of time before access is allow again. Unlike Soft
Mode, time reset mode relax the rule yet remind cardholder of inconvenient encounter
when violate security rules
Note: When APB Hard mode is in use, often users who do not follow the entry/exit
procedure may assume the system malfunctions when entry is denied. Therefore it is
important all Cardholders be aware and follows the procedure.
