Abstract
A thermally sensitive stored chemical energy capsule is formed in the heat collector or attached to the fusible link of existing thermally sensitive sprinkler heads for activating individual sprinkler heads by heat generated by the intermingling of the capsule contained chemicals.
Claims6
An exothermic release for a thermally sensitive sprinkler head having a fusible element normally maintaining the sprinkler head inactive, the improvement comprising:
- a thermally sensitive heat generating capsule disposed adjacent said fusible element,
- said capsule confining a heat expansible medium with a quantity of sodium and containing water;
- and,
- partition means capable of being ruptured by the expansion of said expansible medium beyond a predetermined limit for commingling said sodium and water and fusing said fusible element, normally separating said sodium and expansible medium from said water.
