Abstract

La présente invention concerne un dispositif de commande de voyant lumineux avertisseur permettant d'indiquer la pression résiduelle dans un réservoir d'air comprimé et, plus particulièrement, un dispositif de commande de feu avertisseur permettant d'indiquer la pression résiduelle d'un réservoir d'air comprimé comprenant : des ampoules à LED conçues pour être fixées sur les deux faces de sangles servant à transporter un réservoir d'air comprimé sur le dos, les ampoules étant utilisées comme lampes lors d'une extinction d'incendie ; un avertisseur de pression de 55 bars, raccordé aux ampoules à LED, permettant de détecter la quantité d'air résiduel à l'intérieur du réservoir d'air comprimé et de notifier au porteur un temps pour recharger l'air, les ampoules à LED scintillant si la pression interne du réservoir d'air comprimé chute à 55 bars ou en dessous de sorte que la quantité résiduelle du réservoir d'air comprimé peut être identifiée à l'œil nu même dans un environnement sombre et bruyant d'une scène d'incendie, ce qui permet aux pompiers de s'échapper rapidement du site de travail ; un commutateur de blocage principal pour bloquer l'alimentation électrique si les ampoules à LED ne sont pas nécessaires de façon à réduire la consommation de courant ; et un commutateur d'éclairage pour commander l'alimentation des ampoules à LED servant de lampes de façon à les utiliser conformément à l'environnement de la scène d'incendie.
