In the particular embodiments disclosed in the specification, a residential sprinkler arrangement includes a sprinkler body with an axial passage having an outlet opening providing a K factor of about 4 to about 6 which is normally closed by a cap retained in position by a thermally responsive element and a planar deflector spaced from the outlet opening and supported from the sprinkler body by a pair of frame arms. The deflector has a circumferential array of peripheral slots, a first set of which, located in the plane of the frame arms, has a length greater than that of any of the other slot-like openings and a second set of which, located in the plane perpendicular of the plane of the frame arms, has a length less than that of the first set but greater than that of any of the other slots. A third set of four slots, located at 45° to the plane of the frame arms, has a length less than that of the second set but greater than that of a fourth set of eight slots which are located at about 13° from each of the plane of the frame arms and the plane perpendicular to the plane of the frame arms and a fifth set of slots, located between the slots of the third and fourth sets extends substantially parallel to the slots of the third set of the slots.
