<p>The system has an inner unit (1) connected with an outer unit (26) by a cable (20). The inner unit has a power supply unit (16) that is connected to a network connection (15) at an input side and produces reduced voltage at an output side. The inner unit has a non-isolated relay (10) for controlling a door closure (43) of an access door. The inner unit is provided with an evaluation, processing and storing unit (5). The relay applies the reduced voltage to the door closure during controlling by the evaluation, processing and storing unit.</p> |
