1. A fire protection device comprising:
a frame including:
a body having an inlet and an outlet disposed spaced along a longitudinal axis to define a passageway with a nominal K-factor of 16.8 or greater, the body having a proximal end for coupling the fire protection device to a fluid supply line, the body having a distal end opposite the proximal end;a pair of arms disposed in a first plane generally parallel to the longitudinal axis, the arms being coupled to the distal end of the body; and a deflector assembly coupled to the arms, the deflector assembly including:
a generally planar face portion distally spaced from the outlet of the body and substantially orthogonal to the longitudinal axis, the face portion further including two openings disposed on opposing sides of a second plane perpendicular to and intersecting the first plane along the longitudinal axis;a canopy portion supported on a first side of the first plane and spaced from a first perimeter section of the face portion disposed on the first side of the first plane; anda plurality of tines extending along a second perimeter section of the face portion disposed on a second side of the first plane opposite the first side, each of the tines having an outer edge defining an arc length of a common circle having a center aligned along the longitudinal axis. |
