DESCRIPTION
The SHIELD Sprinkler, SD1025, SD1026 (Glass Bulb Type)
½
” Orifice, Conventional sprinkler is designed for standard or
recessed installation. 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 finishes 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 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 = 229
square feet(20.9 sq.m); Ordinary Hazard = 130 square
feet(12.1 sq.m)per NFPA 13.
