Abstract

Ein Branderkennungsverfahren beruht auf der Auswertung der Streulichtsignale, die ein mit einem Streulichtsystem ausgestatteter Brandmelder unter zwei Streuwinkeln mißt. Ein Mikroprozessor in dem Brandmelder gewinnt aus den Streulichtsignalen durch Vergleich mit einer Alarmschwelle einen Alarmwert. Zur Erkennung der häufigsten Rauchtypen und insbesondere zur Auswertung von Mischbränden mit geringem Fehlalarmrisiko wird der Alarmwert in Abhängigkeit von dem Verhältnis der Streulichtsignale bestimmt.
