ABSTRACT:
A sidewall fire sprinkler head includes a frame with tubular body and a deflector supported from the frame. The deflector has a face portion, generally planar, which is supported generally perpendicularly to a longitudinal central axis of the frame, and a generally planar canopy portion, which is supported from the face portion on an upper side of the face portion and oriented generally horizontally when the sprinkler is installed. An opening between the face portion and the canopy portion permits water to pass through the deflector and be directed by the canopy portion to the remote side of the protected area directly opposite the sprinkler from the remote corners of the protected area. At least one additional opening is provided on the lower side of the face portion below the central axis. A fin portion of the deflector is provided positioned transversely to the face portion and forming a lower side on the additional opening to direct water discharged away from the central axis and downwardly towards the opening through the deflector generally parallel to the central axis and even back up towards the central axis to supplement the water being directed to the remote area directly opposite the head.
