SIDEWALL SPRINKLER EXTENDED COVERAGE
MODEL: SD1125
The
Model A SD1125 ½”orifice, extended coverage horizontal sidewall sprinkler is
designed for extended coverage or recessed installation. The design provides a
crescent-shaped water discharge pattern for installation along a wall or under
a beam or ceiling. The design incorporates state-of-the-art, heat responsive,
frangible glass bulb design (quick response) for prompt, precise operation. The
die cast frame is more streamlined and attractive than traditional sand cast
frames.
It
is cast with a hex-shaped wrench boss to allow easy tightening from many
angles, reducing assembly effort. This sprinkler is available in various
temperature ratings and finishes to meet many design requirements. The recessed
pendent should be utilized with a Model A recessed escutcheon which provides up
½” of adjustments.
