Abstract of the Disclosure A fire-protection sprinkler head with an improved response characteristic is disclosed. A fusible link is provided with a fin having multiple face portions oriented to direct air currents from any of a plurality of orthogonal directions over the fusible region of the link. An embodiment with multiple fins provides an aggregate set of face portions that direct over the fusible region air currents that have X, Y, and Z orthogonal components in both positive and negative senses. Air currents can be directed both by deflecting effects and air foil effects. Preferably the face portions are facets formed integrally with sheet metal body members that form the link. In the preferred embodiment the link and all fins are formed of a pair of similar stampings from sheet metal.
