Abstract

A fire protection sprinkler having a sprinkler head of the type in which the sealing system comprises a glass ampoule, which contains a suitable liquid having a high coefficient of thermal expansion, is activated in that in the event of an abnormal rise in temperature the liquid contained in the glass ampoule bursts the ampoule from inside and thereby releases the sprinkler sealing system. Supplementing this temperature-dependent activation system with a UV-sensitive activation system comprising an electrically fired pyrotechnic detonator 10, which is coupled to a UV-sensitive detector 16 and which when activated by the detector 16 fires a powder body 14 against the ampoule 4, which breaks the ampoule 4 from outside and is at the same time split up into individual grains of powder, provides security for an unfailing activation of the fire protection sprinkler. A sprinkler head adapted to the method has a detonator 10 designed for electrical firing, which is provided with a primer charge in the form of a powder body 14 arranged in the detonation direction and is fitted to a shackle 2, in which the glass ampoule 4 is held, its detonation direction points towards most central part of the ampoule. <IMAGE>
