Title
(EN) A DETECTOR FOR A FIRE ALARM SYSTEM
(FR) DÉTECTEUR DE SYSTÈME D'ALARME INCENDIE
Abstract
(EN)
A detector (10) for a fire alarm system (100) includes first and second sensing elements (14a, 14b) for detecting the occurrence of a fire in a monitored environment. Depending on whether neither, one or both sensing elements (14a, 14b) detects a fire, the fire alarm system (100) is controlled in a different manner to perform different alarm responses. The first and second sensing elements (14a, 14b) may have different operating characteristics, which reduces the likelihood of both bulbs malfunctioning at the same time or for the same reason which may otherwise cause a false alarm.
(FR)
L'invention concerne un détecteur (10) d'un système d'alarme incendie (100) comprenant des premier et second éléments de détection (14a, 14b) destinés à détecter l'apparition d'un incendie dans un environnement surveillé. En fonction du fait que ni un ni les deux éléments de détection (14a, 14b) ne détectent un incendie, le système d'alarme incendie (100) est commandé de manière différente pour mettre en œuvre différentes réponses d'alarme. Les premier et second éléments de détection (14a, 14b) peuvent avoir différentes caractéristiques de fonctionnement, ce qui réduit la probabilité de dysfonctionnement des deux éléments de détection en même temps ou pour la même raison qui peut autrement provoquer une fausse alarme.
