In addition, each updating unit (1) includes means for the bi-directional transfer of data in relation to user credentials (4) and the central control unit (2). The updating unit (1) transfers only the information concerning a particular user and the installation closure plan to the user credentials (4), while receiving information stored on the user credential (4) relating to past events associated therewith, which have been transferred to each of the access elements (3).
