Abstract

Verfahren zum Betrieb eines optischen Rauchmelders, bei dem zur Detektierung von Rauch mindestens ein lichtempfind­ licher Empfänger die Nutzstreustrahlung mißt, die von einem Raumelemnt ausgeht, das im Kreuzungsbereich des gerichteten Gesichtsfelds des lichtempfindlichen Empfängers und des gerichteten Strahls einer Lichtquelle liegt, wobei zur Detektierung der durch Verschmutzung der Meßkammer hervor­ gerufenen Störstreustrahlung der lichtempfindliche Empfän­ ger oder ein zweiter lichtempfindlicher Empfänger die Strahlung erfaßt, die von einem Flächenelement der Meßkam­ mer ausgeht, dadurch gekennzeichnet, daß die Reflexions­ strahlung eines beleuchteten Flächenelements gemessen wird.
