Defining Controller Options
The Option tab enables operators to configure such features as:
- Anti-passback (for synchronizing entry/exit readers)
- Duress function (for defining a panic button)
- Card count options (for specifying cards in an area), etc.
Note: The anti-passback option works with entry/exit readers. It allows security administrators to keep track of the number of monitored cardholders in an area. It is local to each controller defined by corresponding entry/exit readers. A relay can be activated when the counter reaches the number of cards defined to be inside the area; the relay is disabled when the number of cards in the area goes below the specified number.
