Abstract

Boîtier destiné aux installations de sécurité contre le vol et contre l'incendie permettant la protection des avertisseurs sonores. Il comprend un socle destiné à être fixe sur un support et une partie mobile en relation avec le socle par des ressorts de jonction dont le positionnement, la souplesse et la flexibilité provoquent le déclenchement de l'avertisseur sonore par l'intermédiaire des contacts à rupture fugitive dès que l'on provoque une poussée quelconque sur l'une ou l'autre des faces de la partie mobile.
