Abstract

Sistema de detección y generación de llamada a viviendas para porteros electrónicos. Comprende un circuito detector de llamada al altavoz (1), conectado al altavoz mediante un pulsador (13) de llamada, para que al actuarse éste se aplique la carga del altavoz al detector (1), generando éste una señal de activación de un circuito generador de tonos, cuyas frecuencias generadas se aplican a una etapa de salida del altavoz (7); que está conectado al altavoz para reproducir en éste los tonos. Además comprende una etapa de salida del zumbador (8) y un circuito detector de llamada al zumbador (2), que están implementados por un mismo circuito, el cual a su vez está conectado a la etapa de salida del altavoz (7) a través de un segundo circuito de protección contra cortocircuitos (6), que inhabilita la etapa de salida del altavoz (7) cada vez que se activa la etapa de salida del zumbador, o cuando ésta se conecta con la salida de la etapa de salida del altavoz.System of detection and generation of call to homes for electronic doormen. It comprises a speaker call detector circuit (1), connected to the speaker by means of a call button (13), so that when it is actuated, the speaker load is applied to the detector (1), generating this one an activation signal of a circuit tone generator, whose generated frequencies are applied to a speaker output stage (7); which is connected to the speaker to reproduce the tones in it. It also includes a buzzer output stage (8) and a buzzer call detector circuit (2), which are implemented by the same circuit, which in turn is connected to the speaker output stage (7) through of a second short circuit protection circuit (6), which disables the speaker output stage (7) each time the buzzer output stage is activated, or when it is connected to the output of the speaker output stage .
