Technical
Data
The Omega Model HEC-12EC
Sprinkler is the most versatile
horizontal sidewall sprinkler ever
produced. It is a low profile,
aesthetically pleasing, wall mounted
sprinkler that operates five to six times
faster than a standard sprinkler. It
offers a high degree of protection for
human life and features a spray
pattern that has been shown to be
effective in the control or
extinguishment of fire.
The Model HEC-12EC carries two
separate Listings* by Underwriters
Laboratories for use as:
1. An Extended Coverage Quick
Response Sprinkler that qualifies
for installation at 4"-12" (101.6mm -
304.8mm) below the ceiling in light
hazard occupancies in accordance
with current NFPA 13 Standards
(for up to 16' x 18' (4.9 mm - 5.5 mm)
coverages).
2. An Extended Coverage Sprinkler
that qualifies for installation 4"-
6" (101.6mm - 152.4mm) below the
ceiling in light hazard occupancies
in accordance with current NFPA
13 Standards (for up to 16' x 20' (4.9
mm - 6.1 mm) coverages).
The Model HEC-12EC is available in
two standard finishes, brass and
chrome plated. Its mating escutcheon
plate is available in three standard
finishes, brass, chrome plated, and
Standard Finishes:
Sprinkler: brass, chrome plated
and white painted
Escutcheon: brass, chrome
plated and white
painted
Length: 2 3/8" (60.3 mm)
Width: 1 3/8" (34.9 mm)
Weight: 4.5 oz. (127.6 g)
white, with additional special finishes
available upon request.
Operation: A fusible alloy pellet is
compressed with a bearing disc into
a copper housing by a ball plunger.
Heat is absorbed by the heat
collecting fins and conducted to the
alloy pellet. At the rated temperature
the alloy melts, causing the ball
plunger to drop, freeing balls from
the retaining groove. This movement
allows system water pressure to
force the orifice sealing mechanism
and deflector assembly open. Water
is then discharged in a designed flow
pattern.

Step 4. Hand tighten the sprinkler
into the fitting. Use an Omega HEC
sprinkler wrench to tighten the
assembly into the fitting. A leak tight
joint requires the application of only
7-14 ft.-lbs. (9.5 to 19.0 Nm) of torque.
A tangential force of 14-28 lbs. (62.3
to 124.5 N)
delivered through a 6" (150
mm)
long rachet handle will deliver
adequate torque. Torque levels over
21 ft.-lbs (28.6 Nm) may distort the
orifice seal, resulting in leakage.
Step 5. To install the escutcheon
plate, align it with and press it over
the sprinkler body until the outer edge
of the escutcheon meets the
mounting surface.
Do not over or under tighten the
sprinkler to compensate for
inaccurate escutcheon plate
adjustment.
Caution: Special care must be
taken when installing with a CPVC
system. Sprinklers must be installed
after the CPVC manufacturer's
recommended setting time for the
primer and cement to ensure that
neither accumulate within the
sprinkler.
Special care must be taken when
installing with a copper system.
Sprinklers must be installed only after
the inside of the sprinkler nipple and
associated fittings have been wire
brushed to remove any flux. Residual
flux can cause corrosion and in
extreme cases can impair proper
sprinkler operation.
Installation In the event of a thread leak,
remove the unit, apply new pipe joint
compound or tape, and reinstall.
Installation Sequence
Step 1. The unit must be installed in
the horizontal position.
Step 2. The face of the sprinkler
fitting should be installed 5/8"±1/8"
(15.9 mm ± 3.2 mm ) behind the finished
wall line. Adjustments are made via
the adjustable sliding escutcheon
plate to compensate for variations in
the fittings.
Do not use the escutcheon plate to
hold the unit in position. The
sprinkler will function properly, only
when the system piping is anchored
to the building structure. Otherwise,
reaction forces from system initiation
could alter the sprinkler alignment
and disrupt the distribution pattern.
Step 3. Use only a non-hardening
pipe joint compound or Teflon* tape.
Apply to the male threads only.
Model HEC-12EC Sprinklers must
be installed in accordance with
current NFPA 13 Standards.
Deviations from these requirements
and standards or any alteration to the
sprinkler itself will void any warranty
made by Central Sprinkler Company.
In addition, installation must also
meet local government provisions,
codes, and standards as applicable.
The system piping must be properly
sized to insure the minimum required
flow rate from the sprinkler.
Prior to installation, check for
proper model, style, orifice size, and
temperature rating. Install sprinklers
after the piping is in place to avoid
mechanical damage; replace any
damaged unit. Wet pipe systems
must be protected from freezing.
Upon completion of the installation,
the system must be tested per
recognized standards.

Care &
Maintenance
Sprinklers must be handled
carefully. They must not be
transported or stored where ambient
temperatures may exceed 100°F/
38°C. For best results, store them in
a cool, dry location in the original
shipping package.
Do not install sprinklers that have
been dropped or visibly damaged.
Sprinklers must never be painted,
coated, plated, or altered in any other
way from manufactured condition or
they may not function properly. Any

sprinklers altered in such manner
must be replaced.
The owner is responsible for the
proper working condition of all fire
protection devices and accessories.
The NFPA Standard 25 entitled,
“Inspection, Testing and Maintenance
of Water-Based Fire Protection
Systems” , contains guidelines and
minimum maintenance requirements.
Furthermore, the local Authority
Having Jurisdiction may have
additional regulations and
requirements for maintenance,
testing, and inspection that must be
obeyed.
It is advisable to have sprinkler
systems inspected regularly by a
qualified inspection service. Length
of time between such inspections can
vary due to accessibility, ambient
atmosphere, water supply, and site
activity.
Do not attempt to re-assemble or
otherwise reuse a sprinkler that has
operated. Replace any sprinkler
exhibiting corrosion or damage;
always use new sprinklers of the
same type and temperature rating as
replacements.
Because the discharge pattern is
critical to protection of life and
property, nothing should be hung or
attached to the sprinkler unit that
would disrupt the pattern. Such
obstructions must be removed. In the
event that construction has altered
the original configuration, additional
sprinklers may need to be installed to
maintain the protection level.
Do not attempt to replace sprinklers
without first removing the fire
protection system from service. Be
certain to secure permission from all
Authorities Having Jurisdiction, and
notify all personnel who may be
affected during system shutdown. A
fire watch during maintenance
periods is a recommended
precaution.
To remove the system from service
mode, first refer to the system
operating guide and valve
instructions. Drain water and relieve
pressure in the pipes. Remove the
existing unit and install the
replacement, using only the
recommended sprinkler wrench. Be
certain to match model, style, orifice,
and temperature rating.
Guarantee: Central Sprinkler
Company will repair and/or replace
any product found to be defective in
material or workmanship within a
period of one year from date of
shipment. Please refer to the current
