Abstract

Improved intercommunication system, characterized in that it comprises an amplifying device provided with an input and an output connected with an electromagnetic switching device, so that the input of the amplifying device can be selectively connected with microphones of a central unit and secondary units, and the output can be respectively connected with reproducing devices of a secondary unit and of the central unit, said electromagnetic device being controlled by control circuits that include control pushbuttons in the secondary units to transmit to the central unit, and by which the input of the amplifier device is connected to an alternating current source or pulsating by means of a call button, so that an audible call signal is produced in the called secondary unit's player device.
