    How to configure the Access Control Module to require Access Granted to Enter and to Exit.

    Secure locations such as safes or cash rooms require users to use a credential to gain access to enter the location, and then again for egress.  This is commonly called a Card In - Card Out application.
    • Requirements:
      •  Access Control compatible Intrusion alarm panel compatible; B8512G/B9512G, B6512 and the various D7412 and D9412 panel types. 
      • Two B901 or D9210C access control modules.
      • (the D9210C must be used on GV4 type panels)
      • Two 26bit wiegand format readers and compatible credentials.  One reader to be used on each door.
      • Use same reader types for both entry and exit to avoid compatibility conflicts between credentials. 
        • Note: The D9210B is only compatible with D7412/D9412, G, GV2 and GV3. Do not use with GV4 or newer panel types.
    •  Installation:
    1. Install a Reader outside of the room and wire to the Primary D9210. This will be the ‘Card-In’ reader.
    2. Install a Reader inside the room and wire to the Secondary D9210. This will be the ‘Card-Out’ reader
    3. Connect the secondary D9210 Form-C normally open contacts to the primary D9210C Request to Exit (REX) terminals.
    4. Connect the primary D9210 Form-C relay contacts to the door locking device.
    • Operation:
    1. Enter the room by presenting the credential to the reader, outside the room, wired to the Primary D9210. Access is granted and the door opens for entry.
    2. Exit the room by presenting the credential to the reader, inside the room, wired to the Secondary D9210. The secondary 9210 Form-C normally open contacts will present a short to the Primary D9210 Request to Exit contacts and the door opens.
    3. If programmed, the Access Granted event generated upon entry is logged by user name.
    4. If programmed, upon exiting the room, a Request to Exit event is logged, however without a user name.
