5 ASSOCIATING DOOR UNIT BUTTONS TO USERS
The main door unit calling buttons must be associated to the users of the different columns if several
columns are present in the system.
BUTTON CODES
Up to 62 buttons (in addition to the basic buttons) may be connected to the door unit using up to 4 button
expansion modules.
By default the buttons are associate to the users from 0 to 63 of the column to which it belongs if the door
unit is confi gured as secondary unit.
If instead the door unit is confi gured as main unit, then the buttons are automatically associated to the
column 0, which simplifi es the installation of main units in single column systems.
