The system has multiple switchgears for preventing arrival of signals of visual documents coming from emission modules on a wiring i.e. wired connection. A set of radio operator receivers is connected with the switchgears, and activates the switchgears in response to reception of a cut-off control radio signal. A set of broadcasting transmitters is connected with manual control units (328) in order to emit the cut-off control radio signal in response to an actuation of the manual control units.
