A KeyKing door exit button is configured in the ACFA Intellect Software System on the TC3XY Reader object's settings pane. This object is created based on a TC3XY Door object on the Hardware tab of the System Settings dialog.

To configure a KeyKing door exit button, do the following:

1. Go to the TC3XY REX Button object's settings pane.
   
2. Select the exit button's normal state from the State dropdown list (1).
3. Select the exit button mode from the State dropdown list: In use or None (2).
4. Click the Apply button (3).

This completes the configuration of the KeyKing door exit button.
