The credential with ID 0 is the system Master Key which is used for programming user
credentials for the UO-4S without UProg and cannot be used for arming / disarming.
In the modes Slave 1 and Slave 2 all the credentials including local ones must be enrolled
in the control panel. Messages about arming and disarming the UO-4S contain ID (the
sequential number) of the user in accordance as they are numbered in the control panel
while the match between ID and the user name is defined in Global credential settings
Setting Global Credentials in the Master Mode
To transmit User ID and User Name while arming and disarming zones/partitions the Global
Credentials table is used.
Figure 18. Global Credentials, Master Mode
Global credentials can be enrolled using the reader or the keyboard (credentials of the PIN type).
In the Master mode the UO-4S cannot control the slave devices and the credentials are
enrolled only for the possibility to transmit credential ID and User Name. So, the same
credentials must be locally enrolled in the devices.
Setting Global Credentials in the Slave 1 or Slave 2 Mode
When the UO-4S operates under the control panel all the credentials including local ones must
be enrolled in the memory of the control panel as described in the control panel’s manual. In this case
the sequence number of a credential will be transmitted by the control panel as a user number (ID). The
match between ID and user names is described in the UO-4S on the tab Credential – Global.
