Abstract

Bei einem rauchempfindlichen Brandmelder, bei­ spielsweise einem Ionisations-Rauchmelder oder einem optischen Streulicht-Rauchmelder, ist neben dem Rauch­ fühler, d.h. der Ionisationskammer (42) oder der Streustrah­ lungs-Rauchmesseinrichtung (36), ein temperaturempfind­ liches Element (39, 40) aus einer Formgedächtnislegierung vorgesehen, beispielsweise Ni55/Ti45, welches nach einer Kaltverformung bei Erwärmung auf eine kritische Tempera­ tur, beispielsweise bei etwa 70° C, in die ursprünglich einge­ prägte Form zurückkehrt und diese Form auch bei nachfol­ gender Wiederabkühlung beibehält. Dieses temperaturemp­ findliche Element (39, 40) aus einer Formgedächtnislegie­ rung beeinflußt durch seine Rückverformung bei Erreichen der kritischen Temperatur den Rauchfühler in der gleichen Weise, wie wenn Rauch vorhanden wäre, beispielsweise indem das Element in den Strahlungsbereich hinein­ schwenkt und den Ionenstrom herabsetzt bzw. Strahlung auf den Strahlungsempfänger streut. Die Alarmsignalgabe erfolgt dabei kontaktlos und sicher mit einer für den rauchempfindlichen Fühler und das temperaturempfindli­ che Element gemeinsamen Auswerteschaltung.
