Abstract

Bei einem Verfahren zur Branddetektion wird an mindestens einer Überwachungsstelle eines Raumes eine Luftprobe entnommen und mittels eines einen elektrischen Antriebsmotor (8) aufweisenden Lüfters (7) über einen Strömungskanal (5) einer Meßkammer (3) mit wenigstens einem Branddetektor (4) zugeführt. Der Volumenstrom der dem Branddetektor (4) zugeführten Luft wird indirekt gemessen, indem Messwerte für die elektrische Leistungsaufnahme und die Drehzahl des Lüfter-Antriebsmotors (8) ermitteltwerden. Aus diesen Meßwerten wird durch Quotientenbildung wenigstens ein Volumenstrommeßwert gebildet und zum Überwachen des Volumenstroms mit mindestens einem vorgegebenen Volumenstromgrenzwert verglichen.
