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 pre-designed
flow pattern.
The Omega Model R-1M
Residential Pendent Automatic
Sprinkler is a low profile, aesthetically
pleasing, ceiling 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 R-1M is Listed* by
Underwriters Laboratories as a
Residential Sprinkler with a K-factor
of 3.9, a temperature rating of
160°F/71°C, and a maximum working
pressure of 175 psi. It qualifies for
installation in residential occupancies
in accordance with current NFPA 13,
NFPA 13D and NFPA 13R.
The Model R-1M Residential
Pendent Sprinkler is available in three
standard finishes, brass, chrome
plated and white painted. Its mating
escutcheon plate is available in three
standard finishes, brass, chrome
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

Omega R-1M
Installation
The Model R-1M Sprinklers must
be installed according to current
NFPA 13, NFPA 13D or NFPA 13R
Standards. Deviations from these
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 minimum required
flow rate at the sprinkler.
Prior to installation, 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; replace any damaged units.
The Model R-1M Pendent
Sprinklers are not listed for use in dry
systems. Wet pipe systems must be
protected from freezing.
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 unit must be installed in
the pendent position. The R-1M
may be installed below a ceiling
with the deflector up to the
maximum allowed by NFPA of 4".
Step 2. The face of the sprinkler
fitting should be installed a nominal
7/16" minimum to 1 1/16" maximum
behind the finished ceiling line.
Adjustments may be made via the
push-on escutcheon plate to
compensate for variations in the
fittings.
Do not use the push-on 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 only to the male threads.
Step 4. Hand tighten the sprinkler
into the fitting. Use a Central
Sprinkler Omega Model R-1
Sprinkler Wrench to tighten the unit
into the fitting. The wrench attaches
easily to any 1/2" socket drive rachet.
A leak tight joint requires the
application of only 7-14 ft.-lbs. of
torque. A tangential force of 14-28
lbs. delivered through a 6" handle will
deliver adequate torque. Torque
levels over 21 ft.-lbs. may distort the
orifice seal, resulting in leakage.

Sprinklers must be handled
carefully. They must not be
transported or stored where ambient
temperatures 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 manner
must be replaced.
The owner is responsible for the
proper operating 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 recommended that sprinkler
systems be inspected regularly by a
Care &
Maintenance
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
Design Requirements — Residential Applications
Special care must be taken when installing with a copper system.
Sprinklers must be installed only after the inside of the sprinkler drop 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.

Step 5. To install the Model R-1A
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.
Readjust the sprinkler fitting as
required.
Never add any leak stopping
additives to a sprinkler system. It
will impair the operation of the
sprinklers and is strictly prohibited.
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.

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 an 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 temperatures should be
inspected, and replaced if need be.
The Authority Having Jurisdiction will
detail minimum replacement
requirements and regulations.
