HORIZONTAL SIDEWALL SPRINKLER

EXTENDED COVERAGE & QUICK RESPONSE

TECHNICAL DATA

DESCRIPTION

Horizontal Sidewall Sprinklers (EC & QR)

HD Extended Coverage Horizontal Sidewall Sprinklers

are Quick Response with 3mm glass bulbs. These

sprinklers are designed for use in light hazard,

commercial occupation such as hotels, restaurants,

offices, etc. The horizontal sidewall sprinklers are

used in place of upright or pendent sprinklers, due to

aesthetics or the building construction where piping

across the ceiling is not desirable. They are installed

along a wall or the side beam just beneath the ceiling.

The spinkler can also be installed with two pieces of

Recessed Escutcheon. The sprinkler can cover 16 feet

wide by 24 feet long area.

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 an uniform water spray pattern to

control or extinguish fire.

INSTALLATION

All HD Sprinklers must be installed according to NFPA

13 Standards. Deviations from these requirements

and standards or any alteration to the sprinkler itself

will void any warranty made by HD Fire. In addition,

installation must also have local government provi-

sions, codes and standards as applicable. The system

piping must be properly sized to insure the minimum

required water flow rate at the sprinkler. Check for

the proper model, style, orifice size and temperature

rating prior to installation. Install sprinklers after the

piping is in place, to avoid mechanical damage. Wet

pipe systems must be protected from freezing. Upon

completion of the installation, the system must be

tested as per recognized standards.

Escutcheon Installation

Use HD escutcheon plate to ensure proper sprinkler

distribution and coverage. To install the escutcheon

plate on recessed sprinklers, align with it and push or

thread over the sprinkler body into the upper support

piece, until the outer edge of the escutcheon meets

the mounting surface.

Installation Sequence

Step1. The unit must be installed in horizontal posi-

tion only.

Step2. Use teflon tape or soft thread sealant only to

the male-threads.

Step3. Hand tighten the sprinkler into fitting.

Step4. For Horizontal Sidewall Sprinklers, use a

standard wrench. Tighten the unit into the fit-

ting. A leak-tight joint requires only 14.7 to

19.6 N-m of torque. Once torque level reach

over 29.4 N-m it may distort the orifice seal,

resulting in leakage. For exposed piping sys-

tems, the sprinkler should be oriented so the

frame are parallel with the branch line pipe.The

word ‘Top’ on the deflector is to face towards

the ceiling.

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 bulb sprinkler if the bulb is cracked or if there is

a loss of liquid from the bulb.

Sprinklers must be installed after the piping is in

place, to prevent mechanical damage.

Use Teflon tape or soft thread sealant on male thread

of the sprinkler for leak tight sprinkler joint. Use

proper wrench. Use appropriate torque. Excessive

tightening torque may distort the sprinkler inlet and

cause leakage. Sprinklers must never be painted,

plated or coated after they leave factory.

INSPECTION TESTING & 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

conditions of sale or contact HD Sales directly.

HD sprinkler described herein must be installed and

maintained in accordance with the latest edition of HD

technical data, latest standards of the 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 devices 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 bulbs are not

a problem, as long as the fluid level has not been

affected. The loss of colour in the liquid will not affect

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.
