A fire extinguishing system has one or more extinguishing units (1) connected together. A heat detector (2) in each extinguishing unit acts as a device for detecting a fire and as a device for triggering an extinguishing process with the aid of a fire extinguishing device (3), which generates a fire extinguishingaerosol spray during the fire. In addition, an electric ignitor (5) and a pyrotechnic electric generator (4) is in each extinguishing unit, and - if several extinguishing units are provided - each pyrotechnic electric generator (4) is connected via wiring (6) to all ignitors (5) in the other extinguishing units. Asensor element of the heat detector (2) consists preferably of a fusible material or of a material with shape memory characteristics. The fire extinguishing system provides a high degree of operational reliability in detecting fires and in extinguishing fires at initial stages, while maintaining favorable characteristics in stand-by operation.

Système d'extinction d'incendie comprenant un ou plusieurs extincteurs (1) raccordés ensemble. Chaque extincteur comporte un détecteur thermique (2) qui détecte un incendie et déclenche un processus d'extinction à l'aide d'un pulvérisateur (3) d'aérosol extincteur pendant l'incendie. De plus, il comprend un allumeur électrique (5) et un générateur électrique pyrotechnique (4). S'il y a plusieurs extincteurs, chaque générateur (4) est raccordé à tous les allumeurs des autres unités par câblage. Un élément sensible du détecteur thermique (2) est constitué préférablement d'un matériau fusible ou d'un matériau à caractéristiques de mémoire de forme. Le système d'extinction d'incendie est très fiable pendant la détection et l'extinction des incendies au stade initial, tout en conservant des caractéristiques favorables pendant l'attente.
