Abstract

L'invention concerne un système de crépine d'incendie comprenant des dispositifs de crépine (1) individuels dotés de capteurs d'alarme (19-22) respectifs, ces capteurs étant connectés à une alarme commune (6). L'actionnement d'un capteur d'alarme (19-22) déclenche une alarme (4), et une indication de localisation du capteur actionné (19-22) est fournie. Les dispositifs de crépine (1) sont dotés d'une sortie d'eau (12) bloquée par une amorce (15-17) thermofusible ou thermocassable, et associés à une plaque de couverture (19) qui normalement obture la sortie (12) et s'abaisse lorsque la température s'élève à un niveau prédéterminé. Un capteur (19-22) comprend un circuit électrique formé à travers la plaque de couverture (19). Ladite plaque de couverture (19) est maintenue en place au moyen de broches verticales (20) fixées à la plaque (19) par une soudure (20a), et emboîtées dans des douilles (21) disposées sur un logement en plastique (8) de dispositif de crépine (1).
