The opening of the locks and all security-relevant configuration settings of the locking system are protected from unauthorized access by codes (formed from the digits 0 to 9). After the initial start and addressing of the locking system, only the Opening Code OCa of each lock (see section 5.2.2 "Standard code types") is activated and set to the factory code “10203040”. With the factory code, the locks can be opened and the Opening Code OCa can be changed to an individual code. As soon as the Opening Code has been changed to an individual OCa code, only the Opening Code and the Master Code OCb can be activated with the Opening Code OCa. If the Master Code
is enabled, the Opening Code OCa loses the authorization to change other codes. Codes can only be enabled, modified, and deleted with the Master Code (MA..), or, if activated, the Mutation Code (MU.) of the respective lock.
To be able to use all functions of the locking system, at least the Opening Codes OCa and OCb and the Master Code must be activated for each lock (see section 5.2.4.1 "Setting the Opening Code OCa.., OCb.. and Master Code").
On existing systems using ID+PIN mode, the factory code of newly added locks is "0010203040".
During operation, it is not acceptable to use the factory code as the opening code (due to security reasons). Therefore, setting a code to the factory code will deactivate this code immediately upon saving.
