TECHNICAL DATA

DESCRIPTION

Pendent Concealed Sprinklers

HD Pendent Concealed Sprinklers are thermo-sensitive

glass bulb sprinklers having decorative flat cover plate

designed to conceal the sprinkler for smooth ceiling.

The cover plates are available in several decorative

finishes to match architectural requirements. The

unique design allows installation and testing of the

sprinkler prior to installation of the cover plate with

cup. Sprinkler housing is threaded to fix cover plate

with cup assembly to provide 6.5 mm (1/4”) vertical

adjustment.

The cover plate and cup design allows installation

of the sprinkler and pressure testing of the fire

fighting system prior to installation of a suspended

ceiling or final painting of the ceiling. The sprinkler

cover assembly can be removed and reinstalled for

removal of ceiling panels for access to building service

equipments. HD Pendent Concealed Sprinklers

are Standard Response (5mm glass bulb) or Quick

response (3mm glass bulb) with standard coverage.

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 of cover plate is reached, the

solder melts and cover plate detaches & falls down.

Further, when rated temperature is reached, the

bulb shatters and water flows through the sprinkler

and strikes deflector, forming an 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 bulbs sprinkler if the bulb is cracked or if there

is a loss of liquid from the Bulb.

Sprinkles must be installed after the piping is in place,

to prevent mechanical damage.

Do not attempt to make-up for insufficient adjustment

in the cover plate by over tightening the sprinkler.

Installation

1. The unit must be installed in the Pendent position

for the Concealed Sprinkler.

2. Use only a non-hardening pipe joint compound or

tape seal. Apply only to the make threads.

3. Hand tighten the sprinkler into fitting.

4. For Concealed Sprinklers, use a HD sprinkler

wrench. Tighten the unit into the fitting. A lead-

tight joint requires only 7 to 14 ft.-lbs (9.5 to

19.0Nm) of torque. A tangential force of 14 to

28 ft.-lbs (62.3 to 124.5N) delivered through a

6”(150mm) handle will deliver adequate torque. If

the torque level reaches over 21 ft.-lbs (28.6 Nm)

it may distort the orifice seal, resulting in leakage.

For exposed piping systems, the sprinkler should

be oriented so the frame arms are parallel with the

branch line pipe.

5. The HD sprinkler described herein must be installed

and maintained in accordance with the latest

edition of HD technical data, the latest standards

of the 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 devices in proper operating

condition.

Inspection Testing and Maintenance

Refer to NFPA 25 for inspection testing and

maintenance requirement or to the authority having

jurisdiction. For detail of warranty refer HD’S current

price list, conditions of sale or contact HD sales

directly.

Sprinklers must never be altered after manufacture.

Any alteration such as painting and coating will directly

harm the sprinkler and cause malfunctions. Sprinkler

in contact with corrosive products should be replaced

if they cannot be cleaned completely.

Visual inspections are recommended after installation.

After installation, a close-up inspection annually will

suffice.

Inspection and maintenance of fire protection system

is the resposibility of the owner. It is recommended

that automatic sprinkler system be inspected and

tested according to local and/or national regulations.

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.

Caution

1. The Sprinkler must be installed and maintained in

compliance with this document.

2. In false ceiling, a cut out must be to minimum

55mm & maximum 68mm, and must be concentric

to sprinkler. A template gauge must be used to

check the cut out to avoid damage or improper

fitment of cover.

3. Sprinkler adjustment with reference to false ceiling

is 6.6 mm. For more details, refer figure in Page-3.

4. Improper fitment may result into fall of cover

plates.

5. Cover plates must be installed only after hydro-

testing and false ceiling painting.

6. Always use HD Wrench for installation. Any other

wrench may damage the sprinkler.
