The Virdi door is configured as follows:

1. Go to the settings panel of the Virdi Door object, which is created on the basis of the Virdi ACU object.
   
2. From the Door number drop-down list (1), select the entry number from 1 to 4.
3. From the Door zone drop-down list (2), select the zone to which this door should belong:
   • *Unassigned* - zone is not assigned.
   • from 1 to 8.

4. From the Door held delay drop-down list (3), select the time in seconds after which the open door will be considered as held: from 0 to 255.

   The total time until the door hold alarm is activated is considered as follows: Open time (see Setting up the Virdi Reader) + Door held delay time. To receive this alarm, the type of zone to which this door belongs should be Exit1, Exit2, Instant, or Interior.

   
   

5. Set the Enable door force check box (4) if it is necessary to monitor the holding of the door.
6. Set the Door forced audible check box (5) if it is necessary to generate a visual and audible alarm on the reader of this door if the door is held.
