Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE DETECCION DE INCENDIO (1) QUE LLEVA UN DETECTOR DE INCENDIO (7) QUE TRANSMITE UNA SEÑAL ELECTRICA ANALOGICA A UNA UNIDAD CENTRAL (6) PARA INDICARLE O NO LA EXISTENCIA DE UN INCENDIO, SIENDO CONCEBIDA LA UNIDAD CENTRAL PARA MEDIR EL VALOR DE ESTA SEÑAL A INTERVALOS DE TIEMPO REGULARES Y PARA DISPARAR UNA REACCION DE ALARMA SI LA DIFERENCIA ENTRE ESTE VALOR MEDIDO Y UN VALOR DE REFERENCIA ES SUPERIOR A UN UMBRAL PREDETERMINADO. EL VALOR DE REFERENCIA TENIDA EN CUENTA PARA CADA NUEVO VALOR MEDIDO DE LA SEÑAL DEPENDE DE AL MENOS CIERTOS VALORES DE DICHA SEÑAL MEDIDOS ANTERIORMENTE.THE INVENTION REFERS TO A FIRE DETECTION DEVICE (1) THAT CARRIES A FIRE DETECTOR (7) THAT TRANSMITS AN ANALOGUE ELECTRICAL SIGNAL TO A CENTRAL UNIT (6) TO INDICATE OR NOT THE EXISTENCE OF A FIRE, THE UNIT BEING CONCEIVED CENTRAL TO MEASURE THE VALUE OF THIS SIGNAL AT REGULAR TIME INTERVALS AND TO TRIGGER AN ALARM REACTION IF THE DIFFERENCE BETWEEN THIS MEASURED VALUE AND A REFERENCE VALUE IS GREATER THAN A DEFAULT THRESHOLD. THE REFERENCE VALUE TAKEN INTO ACCOUNT FOR EACH NEW MEASURED VALUE OF THE SIGNAL DEPENDS ON AT LEAST CERTAIN VALUES OF THE SIGNAL MEASURED ABOVE.
