~ Description
The Central ROC -Residential
Oplfma"' Concealed, 4.2 K-FactOI',
Residential Pendent Sprinklers are
decorative sprinklers featuring a Hat
cover plate designed for use in residen-
tial occupancies such as homes,
apartments, dormitories. and holefs.
They are to be used in wet pipe
residen~al sprinkler systems for one-
and two-family dwellings and mobile
'1omes per NFPA 130; wel pipe
residential sprinkler systems for
residential occupancies up lo and
including four stories in height per
NFPA 13R; or wet pipe sprinkler
systems for the residential portioos of
any occupancy pet 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 inslalfalion of
the sprinklers and pressure testing of
the lire protection system prior lo
installation of a suspended ceiling or
application of the finish coating to a
fixed ceiling. They also permit removal
of Sllspended ceiling panels for access
to buildfng service equipment without
having to first shut down the fire
protection system and remove spnn-
klers. Also, the separable two-piece
design of the the Sprinkler provides for
1/2 inch {12.7 mm} of vertical adjust-
menl, to reduce the accuracy to wh!Ch
the length of fixed pipe drops to the
sprinkters must be cul.
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
whfle the ceiling is being installed and
finished. The tip of the Cap can also be
used to mark the center of the ceiling
hole into plaster board, ceiling tiles, etc.
by pushing the ceiling product aga,nst
the Cap. When !he ceiling 1nst.1!1ation is
complete, lhe Cap is removed and the
Cover Plata Assembly Installed.
Operation: When exposed to heat from
a fire, the Gover Plate, wtuch is normally
soldered to the Suppon Cup at three
points, faNs away !o expose !he
Sprinkler Assembly. Al !his point the
Deflector supported by the Arms drops
down lo ils operational positron. The
fusible link of the Sprinkler Assembly is
comprised of two Hnk halves whrch are
joined together by a lhin layer of solder.
When the rated temperature is reached,
the solder melts and the two link hillVAS
seperate, which then allows thl'!
sprinkler to activate and flaw water

Physical Characteristic•
The Model ROG Residential Optima"'' Concealed Pendent
Sprinklers utilize a dezincificalion resislant (OZR) bronze
frame and 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 Teflon1"
gasket. The deflector is brass.
Design
Criteria
The Model ROC Residential Optima"' Concealed Pendent
SprinklGrs are UL, C-UL Usled and MEA. Approved for use in
accordance with current NFPA. standards on we! 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 round in Table 1 _ When unique conditions exist
such as sloping ceilings, and when acceptable to the local
aulhority, guidance on the placement of residential sprinklers
on sloped ceilings has been provid8d irt 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 (Hnk) of a Mn-operated Central
Model ROC, which Is adjacerit 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
lhe hydraulic design area.
The Model ROC Residential Oplima111 Concealed Pendent
Sprinklers are onry listed with the Series GB4/ROC Concealed
Cover Plale 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 lo top of deflector
distance, and the maximum allowable coverage arsas. The
single sprinkler flow rate is the minimum required discharge
from the most hydraulically demanding single sprinkler and,
th@ multiple sprinkler flow rate is !he minimum required
discharge from each of the total number of "design sprinklers"
as specilied in NFPA 13D or NFPA 13R.
TIA 99-1 (Tentative Interim Ammandment) with an effective
dale of May 22, 2000 states that the minimum required
discharge from each of Iha "design sprinklers" for systems
designed 10 NFPA 13 mus! be calculated based on delivering
a minimum design density of 0.1 gpm'sq. fl. for each of the
!isled coverage areas shown in Table 1. If the now rates listed
1n Tabre 1 exceed a minimum design densityof0.1 gpm/sq. ft.,
then the flow rates in the fable shall be used. Consult the
authority having jurisdiction regarding the application of this
TIA to the currently adopted NFPA 13.
Model ROG Residential Pendent and Recessed Pendent
Sprinklers must be installed using the obstruction criteria for
axlendf!d coverage sprinklers found in the current edilion of
NFPA 13.
NOTES
Resident/al FINI Sprinkler Systems should_ only be
d11Blgned and Installed by thoN competent and
completely familiar w;th automatic sprinkler system
d••lgn, fnst•"•tlon procedur-es, end t.chnl(ICHIS.
The •prlnkler must be secured in position by firmly
fastening the sprinkler .system pipfng to ~ structure. If
the sprinkler Is not pro,»rly ncured In po•ltfon, rNCtfon
forces rHulting from sprinkl&r opt,ration eould alter Its
orientation snd Its water distribution pattern. The
sprinkler escutcheon cannot btl us«J to hold the 11prfnk~r
In position.
Several criteria may apply to the lnstallatlon and usage of

~ Installation
The Central ROC Residential Optima'"
Concealed Pendent Sprinklers must be
installed in accordance with lhe following
instructions:
NOTES
Damage to the fusible Link Assembly
during Installation can be avoided by
handling the sprinkler by the frams anns
only (i.e., do not apply pressurtJ to the
fusible Link Assembly), and by using the
app,op,1ate sprinkler wrench. Damaged
sprinklers must be replaced.
A leak tight 112 Inch NPT sprinkler joint
should be obtained with a torque of 7 to
14 It.lbs. (9.5 to 19. 0 Nm}. A maKimum of
21 fl.lbs. (28.5 Nm) of torque is to be
used to install sprinklers. Higher levels of
torque msy distort the sprinlder inlet with
consequent leskage or impaimlent of the
sprinkler.

lighten the Sprinkler/Support Cup
Assembly into lhe filling. ROC Wrench
will except a 1/2 inch ratchet drive.
Step 4. Replace the Protective Cap by
pushing it upwards lmfil it bottoms out
against the Support CUp. The Protective
Cap helps prevent damage

instanation and/or during applic.ation of
lhe finish coating of the ceiling. It may
also be used lo locate the (',enter of the
dearance hole by gently pushing the

point of the Cap.
NOTE
As long Rs the Protective CRp 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 dearance hole and in prepara-
tion for installing the Cover Plate
Assembly, remove and dis-
card the Protective Cap, and verify that
lhe 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 Gover Plate/
Retainer Assembly until its flange just
comes in contact With the ceiling. Do not
continue to sorew on the Covs Plate/
