used to mark the center of the ceiling
hole into plaster board, ceiling tiles, etc.
by pushing the ceiling product against
the Cap. When the ceiling installation is
complete, the Cap is removed and the
Cover Plate Assembly installed.
Operation: When exposed to heat from
a fire, the Cover Plate, which is normally
soldered to the Support Cup at three
points, falls away to expose the
Sprinkler Assembly. At this point the
Deflector supported by the Arms drops
down to its operational position. The
fusible link of the Sprinkler Assembly is
comprised of two link halves which are
joined together by a thin layer of solder.
When the rated temperature is reached,
the solder melts and the two link halves
seperate, which then allows the
sprinkler to activate and flow water.
WARNING
The ROC Residential Pendent
Sprinklers described herein must be
installed and maintained in compli-
ance with this document, as well as
with the applicable standards of the
National Fire Protection Association,
in addition to the standards of any
other authorities having jurisdiction.
Failure to do so may impair the
integrity of these devices.
Because of the above cited stipula-
tions and the varied nature of
residential type architecture, there
will be some compartment designs
which cannot be fully sprinklered in
accordance with the recomendations
of NFPA 13, NFPA 13D, or
NFPA 13R. In the event of this
condition, consult the authorities
having jurisdiction for guidance and
approval.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating
condition. The installing contractor
or sprinkler manufacturer should be
contacted relative to any questions.

General
Description
The Central ROC - Residential Optima
Concealed, 4.2 K-factor, Residential
Pendent Sprinklers are decorative
sprinklers featuring a flat cover plate
designed for use in residential occupan-
cies such as homes, apartments,
dormitories, and hotels.
They are to be used in wet pipe
residential sprinkler systems for one-
and two-family dwellings and mobile
homes per NFPA 13D; wet pipe
residential sprinkler systems for
residential occupancies up to and
including four stories in height per
NFPA 13R; or wet pipe sprinkler
systems for the residential portions of
any occupancy per NFPA 13.
The Cover Plate Assembly conceals the
sprinkler operating components above
the ceiling. The separable two-piece
design of the Cover Plate and Support
Cup Assemblies allows installation of
the sprinklers and pressure testing of
the fire protection system prior to
installation of a suspended ceiling or
application of the finish coating to a
fixed ceiling. They also permit removal
of suspended ceiling panels for access
to building service equipment without
having to first shut down the fire
protection system and remove sprin-
klers. Also, the separable two-piece
design of the the Sprinkler provides for
1/2 inch (12,7 mm) of vertical adjust-
ment, to reduce the accuracy to which
the length of fixed pipe drops to the
sprinklers must be cut.
The ROC Residential Pendent Sprin-
klers are shipped with a Disposable
Protective Caps. The Protective Cap is
temporarily removed to install the ROC,
and then replaced to protect the ROC
while the ceiling is being installed and
finished. The tip of the Cap can also be

Criteria
The Model ROC Residential Optima Concealed Pendent
Sprinklers are UL, C-UL Listed and NYC Approved (MEA 7-
95-E) for use in accordance with current NFPA standards on
wet pipe sprinkler systems. These sprinklers with a maximum
ceiling to top of sprinkler deflector distance of 4 inches, have
been investigated for use under smooth flat horizontal ceilings
with slopes up to 2 inches per foot using the hydraulic design
requirements found in Table 1. When unique conditions exist
such as sloping ceilings, and when acceptable to the local
authority, guidance on the placement of residential sprinklers
on sloped ceilings has been provided in Figures 5 -14. This
information will provide the minimum spacing requirements
necessary for preventing the wetting (i.e., cold soldering) of the
heat responsive element (link) of a non-operated Central
Model ROC, which is adjacent to one, which has operated. In
these situations the minimum required sprinkler flow rates
given in Table 1 should be used. Your local authority should
be consulted to determine the number of sprinklers required in
the hydraulic design area.
The Model ROC Residential Optima Concealed Pendent
Sprinklers are only listed with the Series GB4/ROC Concealed
Cover Plate Assembly.
The minimum required flow rates for systems designed to
NFPA 13D or NFPA 13R occupancies are given in Table 1 as
a function of temperature rating, ceiling to top of deflector
distance, and the maximum allowable coverage areas. The
single sprinkler flow rate is the minimum required discharge

Physical Characteristics
The Model ROC Residential Optima Concealed Pendent
Sprinklers utilize a dezincification resistant (DZR) bronze frame
and a monel thermal sensitive link. The sprinkler frame orifice is
sealed with a gasketed spring plate (Belleville Seal) consisting of
a beryllium nickel disc spring that is sealed on both its inside and
outside edges with a TeflonTM gasket. The arms and deflector are
bronze, and the support cup is steel. The cover plate and retainer
assembly are brass.
from the most hydraulically demanding single sprinkler and,
the multiple sprinkler flow rate is the minimum required
discharge from each of the total number of "design sprinklers"
as specified in NFPA 13D or NFPA 13R.
TIA 99-1 (Tentative Interim Ammendment) with an effective
date of May 22, 2000 states that the minimum required
discharge from each of the "design sprinklers" for systems
designed to NFPA 13 must be calculated based on delivering
a minimum design density of 0.1 gpm/sq. ft. for each of the
listed coverage areas shown in Table 1. If the flow rates listed
in Table 1 exceed a minimum design density of 0.1 gpm/sq. ft.,
then the flow rates in the Table shall be used. Consult the
authority having jurisdiction regarding the application of this
TIA to the currently adopted NFPA 13.
Model ROC Residential Pendent and Recessed Pendent
Sprinklers must be installed using the obstruction criteria for
extended coverage sprinklers found in the current edition of
NFPA 13.
NOTES
Residential Fire Sprinkler Systems should only be
designed and installed by those competent and
completely familiar with automatic sprinkler system
design, installation procedures, and techniques.
The sprinkler must be secured in position by firmly
fastening the sprinkler system piping to the structure. If
the sprinkler is not properly secured in position, reaction
forces resulting from sprinkler operation could alter its
orientation and its water distribution pattern. The
sprinkler escutcheon cannot be used to hold the sprinkler
in position.
Several criteria may apply to the installation and usage of
each sprinkler. Consequently, it is recommended that the
sprinkler system designer review and develop a working
understanding of the complete list of criteria prior to
initiating the design of the sprinkler system.
Questions concerning sprinkler installation and usage
criteria, which are not covered by the following
instructions, should be submitted to Central Sprinkler.
Include sketches and technical details as appropriate.
In some instances, the requirements of this document
may concern specifications which are more stringent and
which take precedence over those specified in NFPA 13,
NFPA 13D, NFPA 13R, or by the authority having
jurisdiction.

Installation
The Central ROC Residential Optima
Concealed Pendent Sprinklers must be
installed in accordance with the following
instructions:
NOTES
Damage to the fusible Link Assembly
during installation can be avoided by
handling the sprinkler by the frame arms
only (i.e., do not apply pressure to the
fusible Link Assembly), and by using the
appropriate sprinkler wrench. Damaged
sprinklers must be replaced.
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7 to
14 ft.lbs. (9,5 to 19,0 Nm). A maximum of
21 ft.lbs. (28,5 Nm) of torque is to be
used to install 1/2 inch NPT sprinklers.
Higher levels of torque may distort the
sprinkler inlet with consequent leakage
or impairment of the sprinkler.
Step 1. The sprinkler must only be
installed in the pendent position and with
the centerline of the sprinkler perpen-
dicular to the mounting surface.
Step 2. Remove the Protective Cap.
Step 3. With pipe thread sealant applied
to the pipe threads, and using the ROC
Wrench shown in Figure 1, install and
tighten the Sprinkler/Support Cup
Assembly into the fitting. ROC Wrench
will except a 1/2 inch ratchet drive.
Step 4. Replace the Protective Cap by
pushing it upwards until it bottoms out
against the Support Cup. The Protective
Cap helps prevent damage
to the Deflector and Arms during ceiling
installation and/or during application of
the finish coating of the ceiling. It may
also be used to locate the center of the
clearance hole by gently pushing the
ceiling material up against the center
point of the Cap.
NOTE
As long as the Protective Cap remains in
place, the system is considered to be
"Out of Service"
Step 5. After the ceiling has been
completed with the 2-1/2 inch (66,7 mm)
diameter clearance hole and in prepara-
tion for installing the Cover Plate
Assembly, remove and dis-
card the Protective Cap, and verify that
the Deflector moves up and down freely.
If the Sprinkler has been damaged and
the Deflector does not move up and
down freely, replace the entire Sprinkler
assembly. Do not attempt to modify or
repair a damaged sprinkler.
Step 6. Screw on the Cover Plate/
Retainer Assembly until its flange just
comes in contact with the ceiling. Do not
continue to screw on the Cover Plate/
Retainer Assembly such that it lifts a
ceiling panel out of its normal position. If
the Cover Plate/Retainer Assembly
cannot be engaged with the Support Cup
or the Cover Plate/Retainer Assembly
cannot be engaged sufficiently to contact
the ceiling, the Sprinkler Fitting must be
repositioned.the Sprinkler Fitting must be
repositioned.
A— NFPA minimum of 4", maximum 1/2 of the Listed
spacing that the sprinkler was calculated for.
D— Distance to opposing sloped ceiling.
F & G — Acceptable for angles 0°to 60°.
Figure 13 - Obstruction to Discharge by Intersecting Flat Ceiling
If “D” is “Obstructed” per Figure 13 Graph, then “D” is to be
considered the area of coverage and additional sprinklers
along the horizontal ceiling will be necessary. Only if “D” is
“Acceptable” can “A” be considered 1/2 of the maximum
Listed spacing that the sprinkler was calculated for. Dimen-
sion “A” is measured along the slope.
A— Maximum 1/2 of the Listed spacing that the sprinkler
was calculated for.
D— Distance to intersecting horizontal ceiling.
F— Acceptable for angles 0°to 60°.
Figure 14 - Obstruction to Discharge by an Opposing Sloped Ceiling
If “D” is “Obstructed” per Figure 14 Graph, then the
horizontal distance to the opposing slope is the extent of
coverage and additional sprinklers will be necessary to
protect the remainder of the opposing slope. Only if “D” is
“Acceptable” can “A” equal 1/2 of the maximum Listed
spacing that the sprinkler was calculated for. Dimension “A”
is measured along the slope.
