Claim:
A fire sprinkler comprising: a frame defining a duct adapted to exhaust the flow of a fire suppressing or extinguishing substance, and having a fastener adapted to fasten the frame to a supply line; a trigger coupled to the frame and adapted to block the flow of the fire suppressing or extinguishing substance through the duct during a first mode and to permit the flow of the fire suppressing or extinguishing substance during a second mode; and a deflector coupled to the frame and comprising: a first pair of arcs extending in opposite directions from a central portion, the first pair of arcs curving toward the trigger; and a second pair of arcs extending in opposite directions from the central portion, the second pair of arcs perpendicular to the first pair of arcs; wherein the first and second pair of arcs cooperate to redirect the flow of the fire suppressing or extinguishing substance into an elliptical spray pattern that covers an elliptical coverage area having a length, a width, a first axis of symmetry extending along the length of the coverage area, and a second axis of symmetry extending along the width of the coverage area, wherein the width of the coverage area is substantially less than the length of the coverage area.
