Abstract: The invention relates to a method for thermally initiated triggering of an aerosol fire extinguisher having a strike pin (6) acted upon by an inner spring (7) and locked in the stand-by state, and after thermal initiation, the lock is removed and the strike pin (6), driven by the force of the inner spring (7), strikes against a mechanical firing cap (1), whereby an initial firing material is released in the firing cap (1), igniting a booster charge (2), the hot conversion gas thereof igniting a pyrotechnic extinguisher charge in the aerosol fire extinguisher. In order that an absolutely reliable initiation takes place under the same conditions throughout the entire service life of the aerosol fire extinguisher, it is proposed that only immediately after the thermal initiation, when the firing pin (6) is still locked, the inner spring (7) is brought to the necessary tension for triggering the firing cap (1), and only after reaching said tension is the lock of the firing pin (6) automatically released.

The ball can be tossed or rolled towards fires in difficult to reach areas. Exposure to heat opens the valve in the valve assembly to thereby disperse the contents of the body and extinguish the flames.

Abstract: The present invention is directed to overcome such a problem associated with a sprinkler head made of In-based alloy with no use of Pb or Cd that in contradiction with the fact that a testing temperature in a strength test of a sprinkler head is proximal to a melting temperature of a solder alloy used in a heat-sensitive decomposition structure of the sprinkler head, and therefore a good creeping property over a higher temperature zone in which a sprinkler is activated is required, typically, the sprinkler head made of the In-based alloy with no use of Pb or Cd could not achieve the creeping property over the higher temperature zone in which the sprinkler is activated as favorably as any conventional sprinkler head using Pb or Cd could do, and could occasionally end in failure in a durability test. To solve the above problem, the present invention provides an alloy usable for a heat-sensitive material in a sprinkler head, which is composed of Sn in an amount of 0.1-2.
