Description
than the recommended 2 1/4"
diameter. The escutcheon closure
plate fits between the base of the
escutcheon and the mounting
surface.
For all models of ProhibitorTM
sprinklers, an optional 4 1/2"
diameter x 1/8" thick security closure
plate is available for use where
additional security is a consideration.
The security closure greatly reduces
the possibility of inserting a tool,
prybar or other device behind the
sprinkler. The security closure plate
fits between the base of the
escutcheon and the mounting
surface.
For all models of ProhibitorTM
Sprinklers, the optional Ident-A-FireTM
feature is available to provide an
alarm signal upon activation of the
sprinkler.
ProhibitorTM Sprinklers are
available in two standard finishes,
chrome and brass. Their mating
escutcheon is available in three
standard finishes, chrome plated,
brass plated and white painted, with
additional special finishes available.
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.
The Omega ProhibitorTM Model
HEC-12 PRO Automatic Sprinklers
have been specifically designed for
use in institutional occupancies, such
as correctional facilities and mental
health facilities, where the occupants
may attempt to tamper with or
otherwise employ the sprinkler to
injure themselves or others.
The horizontal sidewall style
ProhibitorTM HEC-12 PRO sprinklers
are recessed into the mounting
surface with only a portion of the heat
collecting fin assembly projecting into
the protected space. The heat
collecting assembly has an average
breakaway load of 68 lbs., and a
maximum breakaway load of 85 lbs.
Unlike other institutional sprinklers,
the escutcheon plate and optional
closure plates are firmly attached to
the recessed sprinkler body with
tamper resistant retaining screws.
The Omega ProhibitorTM sprinklers
are designed with an aesthetically
pleasing, low profile silhouette. They
feature a spray pattern that has been
shown to be effective in the control or
extinguishment of fire.
The Model HEC-12 PRO is a
Horizontal Sidewall Sprinkler Listed
for standard sidewall applications with
the deflector positioned 4" to 12"
below the ceiling.
For all models of ProhibitorTM
Sprinklers, an optional 3 5/8"
diameter light gauge escutcheon
closure plate is available, for use
where the wall penetration is greater

Step 5. To install the escutcheon
plate (and closure plate if applicable),
align it (them) with and press it (them)
over the sprinkler body until the outer
edge of the escutcheon
(or closure plate) meets the
mounting surface. Do not over or
under tighten the sprinkler to
compensate for inaccurate
escutcheon plate adjustment.
Step 6. Install the tamper resistant
retaining screws through the
escutcheon and into the retaining
collar, thereby drawing the
escutcheon (and closure plate) up
tight against the mounting surface.
The tamper resistant retaining screws
can only be installed or removed
using the special tamper-proof
socket.
Caution: Special care must be taken
when installing with a CPVC system.
Sprinklers must be installed after the
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.
Design Requirements - Standard Coverage Applications
Upon completion of the installation,
the system must be tested per
recognized standards.
In the event of a thread leak,
remove the unit, apply new pipe joint
compound or tape, and reinstall.
Installation Sequence
Step 1. The sprinkler must be
installed in the horizontal position 4"
to 12" below ceiling.
Step 2. Install the steel nipple into
the branch line fitting, then slide the
rigid support collar over the nipple
prior to installing the 1" x 1/2"
reducing coupling. The face of the
sprinkler fitting should be installed:
(a) 1 7/16" (±1/16") behind the
finished wall if no closure
plate is utilized.
(b) 1 3/8" (±1/16") behind the
finished wall if the light gauge
escutcheon closure plate is
utilized.
(c) 1 5/16" (±1/16") behind the
finished wall if the security
closure plate is utilized.
The sprinkler nipple must be fitted
with the rigid support collar to prevent
movement of the sprinkler away from
the finished wall surface (see
installation diagram on page 2).
Step 3. Use only a non-hardening
pipe joint compound or Teflon* tape.
Apply to the male threads only.
Step 4. Hand tighten the sprinkler
into the reducing coupling. Use an
Omega HEC sprinkler wrench to
tighten the unit into the fitting. A leak
tight joint requires the application of
only 7 to 14 ft.-lbs. of torque. A
tangential force of 14 to 28 lbs.
delivered through a 6" long handle
will deliver adequate torque. Torque
levels over 21 ft.-lbs may distort the
orifice seal, resulting in leakage.

Installation
ProhibitorTM sprinklers must be
installed in accordance with current
NFPA 13. 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 ensure the proper flow rate at
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.
The Model HEC-12 PRO Horizontal Sidewall Sprinklers are intended for
standard coverage areas and standard flow and pressure requirements as
specified in the current NFPA 13 for light and ordinary hazard occupancies. The
sprinklers must be installed in the horizontal sidewall position, with the deflector
from 4" to 12" below the ceiling.
Sprinklers must be handled care-
fully. They must not be transported
or stored where ambient tempera-
tures may exceed 100oF/38oC. 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 a manner
must be replaced.

The NFPA Standard 13A entitled,
“Care and Maintenance of Sprinkler
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 discharge 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 special
sprinkler wrench. Be certain to match
model, style, orifice, and temperature
rating.
A fire protection system that has
been shut off after activation should
be returned to service immediately.
Inspect the entire system for damage
and replace or repair as necessary.
Sprinklers that did not operate but
were subjected to corrosive elements
of combustion or excessive tempera-
tures should be inspected, and
replaced if need be. The Authority
Having Jurisdiction will detail mini-
mum replacement requirements and
regulations.
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
Price List for further details of the
warranty.
