Abstract
Automatic intercommunication system, characterized in that all the intercommunication devices of the system are connected in parallel to a bipolar conduction of suitable electrical power, automatically making the switching of speech-hearing between two devices at the same time as the rest of the installation are blocked, although it is possible to transmit an emergency signal, by the blocked devices to those in communication, indicating the issuer of the urgency signal, also including means to make calls in general from any device to all the others, as well as a switch that leaves the device in a position indicative of absence.
