Abstract
Un detector 10 multisensorial que comprende: al menos un sensor (12) de incendios; al menos un transductor (14) de audio para convertir una señal acústica incidente en una señal eléctrica; unos circuitos (18) de control acoplados a al menos un sensor (12) de incendios y una señal eléctrica; y una interfaz (24) para la comunicación con un sistema (30) de monitorización desplazado; en donde: el detector (10) comprende además un sensor (16) térmico acoplado a los circuitos (18) de control; los circuitos (18) de control están configurados para establecer la presencia de una condición de fuego en la vecindad del transductor (14) de audio con base en al menos parte de las señales acústicas incidentes emitidas por un incendio presente en una región local predeterminada adjunta al transductor (14) de audio; y los circuitos de control están configurados para ingresar en un modo de detección elevado desde un modo de detección normal en respuesta a uno de los primeros, detectando una condición de alarma de entre el transductor de audio, el sensor de fuego o el sensor térmico, aumentando la sensibilidad de los otros sensores, en donde: si en el modo de detección elevado un segundo del transductor de audio, el sensor de fuego o el sensor térmico detectan una condición de alarma dentro de un periodo de tiempo establecido después de que el primero ha detectado una condición de alarma, los circuitos de control son configurados para desencadenar una alarma de incendio y notificar a un sistema de monitorización desplazado, y si en el modo de detección elevado, un segundo del transductor de audio, el sensor de fuego o el sensor térmico no detectan una condición de alarma dentro de un periodo de tiempo establecido, los circuitos de control son configurados para regresarse al modo de detección normal.
