Abstract

L'invention porte sur un système de détection d'incendie, dans lequel système le bâtiment qui est protégé est divisé en compartiments de fumée SP1, SP2, etc. Les compartiments ont des détecteurs d'incendie à l'intérieur de ces derniers, et il y a un cloisonnement qui retient les produits de combustion dans les compartiments. Le système détermine le niveau normal de contamination de particules dans chaque compartiment à l'aide de la moyenne des sorties des détecteurs dans le compartiment. Un seuil de pré-alarme est établi à un niveau prédéterminé de contamination de particules supérieur à un niveau normal prédéterminé, et la moyenne des sorties de détecteur d'un compartiment est comparée à la moyenne des sorties de détecteur d'un autre compartiment. Le niveau de seuil de pré-alarme est réglé vers le haut ou vers le bas dans le cas où les contaminations de particules dans les compartiments concordent les unes avec les autres, mais sont différentes du niveau de contamination de particules normal prédéterminé établi.
