Title
(EN) PREACTION SPRINKLER SYSTEM OPERATION BOOSTER
(FR) ACTIVATEUR DE FONCTIONNEMENT D'UN SYSTÈME D'EXTINCTION AUTOMATIQUE À PRÉACTION
Abstract
(EN)
A system includes a gas exhaust line, a valve coupling the gas exhaust line and a pipe, and a control unit generating a command to open and close the valve, the control unit opening the valve to vent gas from the pipe and closing the valve within a period of time. A method includes receiving a command at a valve to open in order to exhaust gas from a pipe of a sprinkler system through a line coupled to the valve, the command corresponding to a command to turn on a pump unit of the sprinkler system, determining that liquid provided at an output of the pump unit is present in the pipe, and receiving a command at the valve to close in order to prohibit a flow of the liquid through the line.
(FR)
L'invention concerne un système comprenant une conduite d'évacuation de gaz, une soupape reliant la conduite d'évacuation de gaz et un tuyau, et une unité de commande émettant une commande d'ouverture et de fermeture de soupape, l'unité de commande ouvrant la soupape pour évacuer les gaz du tuyau et fermant la soupape au cours d'un intervalle de temps. L'invention concerne également un procédé comprenant la réception par une soupape d'une commande d'ouverture pour évacuer les gaz d'un tuyau d'un système d'extinction par une conduite reliée à la soupape, ladite commande correspondant à une commande de démarrage du groupe de pompe du système d'extinction automatique, la détection de la présence dans le tuyau d'un liquide fourni en sortie du groupe de pompe, et la réception par la soupape d'une commande de fermeture afin d'empêcher l'écoulement de liquide par la conduite.
