DESCRIPTION
The SD1133, SD1121,
½
” ori ce, standard horizontal sidewall
sprinkler is designed for standard 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 (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.
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.
