Abstract

The invention deals with a system providing: at least one private module 100 for each user, including a common entry phone 12 combined with a primary logic circuit 1 that controls the phone circuit and is connected, by means of its own data line 41, to the corresponding logic circuits of all the other private modules 100 and continuously surveys, as qualified, the state of stimulation or rest of a group of peripheral users 15, at least one of which is an alarm sensor and another a control for one or more specific services; an input module 201, 202 for each external button 29, in which there is a second logic 2 circuit that controls the corresponding phone circuit, quantifying the closure between the external communication and the private call module 100, excluding the phone circuit in all the other private modules and transmitting question messages on line 41 for all the private modules 100, thus controlling the connections. A general surveillance module 300 for the communal condominium connected to line 41 and continuously surveys the state of simulation or rest as well as the alarm system for each private module 100.
