Abstract
A sprinkler for a fire suppression system includes a deflector plate having five different types of slots extending from a periphery of the plate toward a center of the plate along radially extending lines. The slots are arrow shaped, club shaped and key hole shaped. Arrow head slots which align with frame arms supporting the deflector plate are wider than the thickness of the frame arms. Club shaped and arrow shaped slots proximate the plane of the frame arms are asymmetrical with respect to radial lines extending from the center of the plate, while arrow shaped and key hole shaped slots distal to the plane of the frame arms are symmetrical with respect to radial lines extending from the center of the plate.
