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.
