Note
You must enable Anti-Passback in Panel Configuration before you can
enable it here. See the Behaviour Settings section in
Anti-Passback: When enabled, a valid card is required for entry and exit. The card
holder must use the card in the proper IN/OUT sequence—that is, a card presented at
an IN reader must then be presented at an OUT reader, or vice versa—a card
presented at an OUT reader must then be presented at an IN reader.
Anti-Passback Violation: If the user's IN/OUT sequence is invalid, then an
anti-passback violation event is generated for the type of anti-passback chosen (Hard
or Soft) and the card holder is either denied access (Hard) or allowed access (Soft).
Enabled - Enables the anti-passback feature.
Note
The Hard/Soft and In/Out Anti-Passback options appear only after enabling
Anti-Passback.
Hard - Validates IN/OUT status before allowing entry. A second swipe of the card at
the same type of reader (IN/OUT) causes a Hard anti-passback violation and the user
is denied entry.
Soft - Validates IN/OUT status before allowing entry. A second swipe of a card at the
same type of reader (IN/OUT) causes a Soft anti-passback violation but the user is
allowed entry.
Out - Applies to readers located inside the anti-passback-controlled area. Card
holders use these readers when attempting to exit the anti-passback-controlled area.
Note
With anti-passback, limited use and trace cards do not apply.
In - Applies to readers located outside the anti-passback-controlled area. Card
holders use these readers when attempting to enter the anti-passback-controlled
area.
Select a Duress Output value.
Configures the output that triggers when a card holder enters a duress PIN at a
keypad/card reader. A duress PIN is the PIN a user enters at a keypad when being
forced (for example, during a robbery) to open a door. The card holder enters a PIN
that is either one number higher or lower than the correct PIN. This PIN opens the
door, but it also triggers the designated duress output and produces an alarm event.
For example, if the PIN is 2222, entering either 2221 or 2223 opens the door, but
triggers a duress pulse and generates an alarm. In this way, the card holder notifies
others without detection by the unauthorized person.
Note A PIN ending in 0 (for example, 2320) will only trip a duress output when a 1
is used in place of the 0 (for example, 2321).
