A horizontal sidewall fire protection sprinkler is provided, including a deflector having a vertical face, transverse to the fluid flow from the output orifice, and a horizontal shelf positioned above and perpendicular to the vertical face. A portion of the horizontal shelf extends in the fluid flow direction by a first length, with respect to the vertical face, and this first length is less than about half of a total length of the horizontal shelf in the fluid flow direction. The sprinkler is installed in a support cup having a raised mounting platform configured to receive the sprinkler body and a cylindrical outer surface, with a front edge in a fluid flow direction, and a back edge. The mounting platform of the support cup is closer to the front edge of the support cup in an axial direction thereof than to the back edge.
