A dome shaped deflector member is centered, axially aligned with the sprinkler axis, and spaced from the outlet. The deflector member has an outer surface and an inner surface that preferably includes: a peripheral region, a central region and an intermediate region. The intermediate region includes a primary deflecting surface, and a secondary deflecting surface that is surrounded by the primary deflecting surface The deflector member provides for generation of a non-circular spray pattern defined by four zones of fluid density concentrically formed about the sprinkler axis.
