Abstract

La présente invention concerne un procédé de surveillance d'une pièce à l'intérieur d'un bâtiment pour détecter l'apparition et/ou la présence de fumée et/ou de certains gaz. Le procédé décrit consiste à aspirer une quantité d'air hors de la pièce au moyen d'une conduite (110) qui est installée dans le bâtiment également pour d'autres usages que la détection de fumée et/ou la détection de certains gaz et qui n'est pas destinée à être utilisée dans une installation de climatisation; à amener l'air aspiré vers un dispositif de détection (130); et à analyser l'air amené pour détecter la présence de fumée et/ou de certains gaz au moyen du dispositif de détection (130). Le procédé peut en outre comporter l'acheminement d'un agent d'extinction depuis un dépôt d'agents d'extinction (150) jusqu'à la pièce surveillée, au moyen de la conduite (110). L'invention concerne en outre un dispositif de surveillance d'une pièce, à l'intérieur d'un bâtiment, pour détecter l'apparition et/ou la présence de fumée. L'invention concerne encore un procédé d'installation d'un système de surveillance d'une pièce à l'intérieur d'un bâtiment pour détecter l'apparition et/ou la présence de fumée et/ou de certains gaz.
