Abstract

System for detecting and generating calls to homes for electronic intercoms.It includes a speaker call detector circuit (1), connected to the speaker using a call pushbutton (13) so that, when the pushbutton is activated, the load of the speaker is applied to the detector (1), in which the latter generates an activation signal of a tone generating circuit whose generated frequencies are applied to an output phase of the speaker (7) which is connected to the speaker in order to reproduce the tones.It also includes a buzzer output phase (8) and a call detector circuit to the buzzer (2) that are implemented by the circuit itself, which in turn, is connected to the speaker (7) output phase through a second short-circuit protection circuit (6), which disables the speaker (7) output phase each time the buzzer output phase is activated or when the latter is connected to the output of the speaker output phase.
