Abstract
A method and apparatus for releasing a sprinkler head (1, 2, 3, 5, 6, 7, 8) are disclosed in which a compacted body (14) of fine particles of a material such as antimony is shot by means of a radiation responsive detector (16, 17, 18) and detonator (9, 10, 11, 12, 13) into contact with a hollow glass bulb (4) which normally prevents operation of the sprinkler, thereby shattering the bulb, disintegrating the compacted body and releasing the sprinkler.
