Abstract

INSTALACION DE ALARMA CONTRA INTRUSOS.COMPRENDE VARIOS PERCEPTORES (SN), CADA UNO DE LOS CUALES CONSTA DE DOS RESISTENCIAS (RA, RN) CONECTADAS EN SERIE, Y DE UN INTERRUPTOR CONECTADO EN PARALELO CON LA PRIMERA RESISTENCIA. LOS PERCEPTORES ESTAN CONECTADOS EN SERIE ENTRE SI, Y CON UNA FUENTE DE ALIMENTACION DE CORRIENTE CONSTANTE (CS). LA TENSION GENERADA A TRAVES DE LOS PERCEPTORES ES APLICADA A UNA DISPOSICION DE CIRCUITO. UN CONVERTIDOR ANALOGICO-DIGITAL (AD) RESPONDE A LA SALIDA DE LA DISPOSICION DE CIRCUITO, PARA ENTREGAR UNA SALIDA DIGITAL A UNINDICADOR (IN) QUE ADVIERTE DE LA ACTUACION DE CUALQUIER PERCEPTOR.
