Abstract

La présente invention concerne un détecteur d'incendie ayant un haut-parleur intégré qui peut générer une alerte incendie vocale. Le haut-parleur est retenu par un tube en forme de toile d'insecte recouvrant une tête de détection pour détecter des conditions d'incendie. Parce que le haut-parleur est ajusté conjointement avec le tube en forme de toile d'insecte à la tête de détection, le haut-parleur peut être placé plus bas que la tête de détection de sorte qu'un message d'alerte incendie vocal puisse atteindre toute la salle.
