Abstract

In the fire protection sprinkler arrangement described in the specification, a VELO ECOH has a sprinkler body with an axial passage for delivery of water and a deflector supported from the sprinkler body by a pair of frame arms. The deflector has a substantially planar central region and a peripheral portion bent toward the sprinkler body along a circular bend line at an angle of about 45.degree. from the plane of the central region. The perimeter of the deflector has four arcuate segments disposed at 90.degree. angles and four substantially straight line segments interposed between the arcuate segments and includes twelve slots extending inwardly from the perimeter. The slots adjacent to the arcuate segments extend approximately parallel to perpendicular axial planes intersecting those segments and the other slots extend radially inwardly from locations centered in the substantially straight line segments of the periphery.
