Abstract

Brandmeldeanlage mit erhöhter Intelligenz, die es ermöglicht, zwischen Schwelbränden und Bränden mit offe­ nen Flammen zu unterscheiden. Dies wird dadurch erreicht, dass die Brandmeldeanlage zwei Fühlerelemente unter­ schiedlichen Funktionsprinzips aufweist und dass die Aus­ werteschaltrnng Schaltungselemente enthält, die den Quo­ tienten der von den beiden Fühlerelementen erhaltenen Signale bilden. Die unterschiedlichen Fühlerelemente können in einem einzigen Brandmeldergehäuse vereinigt sein, wel­ ches gleichzeitig die Auswerteschaltung enthalten kann. Fire alarm system with increased intelligence that it allows between smoldering fires and fires with open to distinguish a flame. This is achieved that the fire alarm system under two sensor elements has different functional principles and that the Aus Werteschaltrnng contains circuit elements that make up the quo tients of those obtained from the two sensing elements Form signals. The different sensor elements can be united in a single fire detector housing, wel ches can simultaneously contain the evaluation circuit.
