Anti-passback for two doors
In this mode, the keypad on door 1 is the anti-passback master unit,
and the external card reader on door 2 is the secondary anti-passback
unit. Thus, an anti-passback system suitable for installation in parking
lots is created.
The user can enter the building on door 1 by reading the card on the
access control keypad and can only exit on door 2 by reading the
card on the external card reader. If the user’s entry has not been
registered on door 1, he will not be able to exit on door 2. Also, the
user cannot enter a second time if his exit has not been registered.
Note: The door can only be opened by reading the card for Zone 1.
All other Zone 1 and Zone 2 access modes are invalid.
