When designing the anti-passback areas for your ICPAM system, be aware of the following limitations or requirements:
· To use an EM-100 controller with ICPAM's anti-passback feature, it must have an optional Exit Reader Expansion Module.
· Cisco Gateway, Mx, and EM-100 controllers cannot be used together within a particular anti-passback area. An anti-passback area can use Cisco Gateway controllers, Mx controllers, or EM-100 controllers, but not mix them.
· An EM-100 controller can be configured with only one Anti-passback mode, so adjacent anti-passback areas using EM-100 controllers cannot have different anti-passback modes.
· The Soft-Timed (Grant Access) anti-passback mode is available only for EM-100 controllers.
· A door can only be assigned to the entry of one anti-passback area, and to the exit of one anti-passback area. (It cannot be the entry of two different anti-passback areas, or the exit of two different anti-passback areas.)
· A door can participate in multiple anti-passback areas only when: each area has the same anti-passback mode, and the door has a different purpose (entry versus exit) in each area.
· A set of EM-100 controllers with static IP addresses can manage some of the details for a particular anti-passback area (without involving the ICPAM Server), if the necessary network communication services and ports are properly configured. For more information, see “Default Services and Ports for the EM-100 Controller” in the ICPAM Installation Guide.
· An anti-passback area that uses EM-100 controllers should have a maximum of four controllers.
