DESCRIPTION
Pendent & Upright Sprinklers
HD Pendent and Upright sprinklers are designed for
use in light and ordinary hazards. The temperature
response is standard response (5mm glass bulb)
and quick response (3mm glass bulb). The sprinklers
come with compact design, glass bulb type, available
in several different finishes and temperature ratings.
The pendent sprinklers must be installed in pendent
position, and upright sprinklers are to be installed in
the upright position.
Pendent Recessed Sprinklers are installed with
adjustable or non-adjustable Escutcheon plates (also
termed as Rosette plates). These are intended to
be installed with finished ceilings. Escutcheon plate
adjustment provides convenience in Pendent Sprinkler
installation in case of areas with finished ceilings or
walls.
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 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.
Care and Handling
Sprinklers must be handled with due care, they must
be stored at ambient temprature 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. Use
proper wrench and appropriate torque. 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, the latest standard of National
Fire protection Association (NFPA) and Factory Mutual
(FM) 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.
