Abstract

Ein kombinierter Sensor zur Brandmeldung beinhaltet Sende/Empfangs-Einheiten für Ultraschall und entweder Mikrowelle oder Licht oder für sämtliche Wellenarten. Das Verfahren zur Auswertung verarbeitet die reflektierten und empfangenen Signale so, daß für den Fall eines veränderten Ultraschall-Empfangssignales eine Branddetektion vorliegt, wenn nicht gleichzeitig bei einer weiteren Wellenart eine Bewegung registriert wird.
