Description
HD Conventional sprinkler is designed for standard
installation. The design incorporates state-ofthe-art, heat responsive, frangible glass bulb design
(standard or quick response) for prompt, precise
operation. The sprinkler body is made of brass forging
copper alloy (DZR). This sprinkler is available in various
temperature ratings (see Sprinkler Ratings) and
finishes to meet many design requirements.
All HD Sprinklers are manufactured using the time
proven Belleville seal used exclusively by all major
manufacturers to ensure long life and safe operation.
Escutcheon plate adjustment provides convenience in
Pendent Sprinkler installation in case of areas with
finished ceilings or walls. It directs from 40% to 60%
of total water initially in a downward direction.

Protecting What Matters Most to You
SPRINKLER OPERATION
The Sprinkler operating device is state-of-the-art
heat responsive frangible glass bulb supplied by a
world leader in this innovative technology. The glass
bulb contains fluid which expands when exposed to
heat. When the rated temperature is reached, the
bulb shatters and water flows through the sprinkler
and strikes deflector, forming a uniform water spray
pattern to control or extinguish fire.
Standard spray coverage is up to:
Light Hazard = 196 square feet (18,2 sq.m);
Ordinary Hazard = 100 square feet
(9,3 sq.m) as per NFPA 13.
CARE AND HANDLING
Sprinklers must be handled with due care, they must
be stored at ambient temperature for best results.
Storage as well as any onward shipment is to be made
in original packing only. Sprinklers must be visually
inspected carefully before installation. Sprinklers
visibly damaged, dropped or exposed to temperature
in excess of the maximum ambient temperature
permitted, should never be installed. Never install
any glass blub sprinkler if the bulb is cracked or if
there is a loss of liquid from the bulb. Sprinkler must
be installed after the piping is in place to prevent
mechanical damage.
Use Teflon Tape or soft thread sealent on male thread
of the Sprinkler for the leak tight Sprinkler joint.
A leak-tight 1/2” NPT/BSPT Sprinkler joint should be
obtained by applying maximum torque of 19.0 N-m
(14 lb-ft). Excessive tightening torque may distort
the Sprinkler inlet and cause leakage. Sprinkler must
never be painted, plated or coated after they leave
factory.
The HD Sprinkler described herein must be installed
and maintained in accordance with the latest edition
of HD technical data, latest standard of National Fire
Protection Association (NFPA) or to the standard of
any other authorities having jurisdiction.The owner is
solely responsible for maintaining their fire protection
system and device in proper operating condition.
Exposure to ultraviolet or direct sunlight for extended
period may cause the liquid dye in glass bulb to fade
or lose colour. Colourless or faded coloured bulbs are
not a problem, as long as the fluid level has not been
affected. The loss of colour in the liquid will not effect
sprinkler performance, as long as the bulb is intact
and not damaged. The loss of colour may be an issue
in identifying sprinkler temperature rating, but the
temperature rating is still stamped on the sprinkler
deflector.
INSPECTION, TESTING AND MAINTENANCE
Refer to NFPA 25 for inspection, testing and
maintenance requirement or to the authority having
jurisdiction. For details of warranty, refer HD’s
current price list, conditions of sale or contact HD
sales directly.
