SPRINKLER HEAD
Concealed Sprinkler
MODEL: SD1050, SD1055
DESCRIPTION
The SHIELD Sprinklers, SD1050, SD1055 (Glass Bulb Type)
Standard and Quick Response Concealed Sprinkler, design
incorporates state-of-the-art, heat responsive, frangible glass
bulb design 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 recessed escutcheon which provides up ½" 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 fire, 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 deflector. The deflector is designed to
distribute the water in a pattern that is most effective in controlling
the fire.
MAXIMUM COVERAGE
Standard spray coverage is up to: Light Hazard = 225 square
feet(20.9 sq.m); Ordinary Hazard = 130 square feet(12.1 sq.m) per
NFPA 13.
