DESCRIPTION
The SD2133, SD2121,
½
” ori ce, standard vertical sidewall
sprinkler is designed for standard 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 (standard or 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 nishes to meet
many design requirements. The recessed pendent should be
utilized with a recessed escutcheon which provides up
” of
adjustments. All sprinklers are manufactured using the time
proven Belleville seal used exclusively by all major manufactures
to ensure long life and safe operation.
SPRINKLER OPERATION
The operating mechanism is a frangible glass bulb which contains
a heat responsive liquid. During a re, the ambient temperature
rises causing the liquid in the bulb to expand.
When the ambient temperature reaches the rated temperature
of the sprinkler, the bulb shatters. As a result, the waterway is
cleared of all sealing parts and water is discharged towards the
de ector. The de ector is designed to distribute the water in a
pattern that is most effective in controlling the re.
MAXIMUM COVERAGE
Standard spray coverage is up to:Light Hazard = 196
square feet(18,2 sq.m); Ordinary Hazard = 100 square
feet(9,3 sq.m)per NFPA 13.
