<p>A central locking device for a plurality of active function units and/or passive components of a system, such as e.g. of a building, a production system or of a vehicle, is provided with a signal input device for locking and releasing locking elements which are coupled to the function units and/or the system components and react to the input signal. The signal input device (1) consists of a signal generator (2) which can be activated from outside and a data processing device (3). The data processing device (3) is coupled via a serial interface (5) and a bus line (6) to the function units and/or system components (7). The function units and/or system components (7) each have a transmitting/receiving component (10') which can be activated by the input signal as well as a decoding and drive stage (11) for the implemented locking element (31, 43) so that, as a function of an input signal recognised as admissible, the function units and/or system components can be released or locked. <IMAGE></p> |
