General
Description
The TYCO Series RFII Quick Response
(3-mm bulb) and Standard Response
(5-mm bulb), 5.6 K-Factor, “Royal
Flush II” Concealed Pendent Sprin-
klers are decorative sprinklers featur-
ing a at cover plate designed to con-
ceal the sprinkler. These sprinklers are
optimal for architecturally sensitive ar-
eas such as hotel lobbies, ofce build-
ings, churches, and restaurants.
Each sprinkler includes a Cover Plate/
Retainer Assembly and a Sprinkler/
Support Cup Assembly. The separa-
ble, two-piece assembly design pro-
vides the following benets:
rAllows installation of the sprinklers
and pressure testing of the re pro-
tection system prior to installation of
a suspended ceiling or application of
the nish coating to a xed ceiling.
rPermits the removal of suspended
ceiling panels for access to building
service equipment without having
to rst shut down the re protection
system and remove sprinklers.
rProvides for 1/2 inch (12,7 mm) of
vertical adjustment to allow a mea-
sure of exibility in determining the
length of xed piping to cut for the
sprinkler drops.
The Series RFII Sprinklers are shipped
with a Disposable Protective Cap. The
Protective Cap is temporarily removed
during installation and replaced to help
protect the sprinkler during ceiling in-
stallation or nish. The tip of the Pro-
tective Cap can be used to mark the
center of the ceiling hole into plaster
board or ceiling tiles by gently push-
ing the ceiling product against the Pro-
tective Cap. When ceiling installation
is complete, the Protective Cap is re-
moved and the Cover Plate/Retainer
Assembly is installed.
As an option, the Series RFII Standard
Response (5-mm bulb) “Royal Flush II”
Concealed Pendent Sprinklers can be
tted with a silicone Air and Dust Seal.
(Refer to Figure 5.) The Air and Dust
Seal is intended for sensitive areas
where it is desirable to prevent air and
dust from the area above the ceiling to
pass through the cover plate.
NOTICE
The Series RFII Concealed Pendent
Sprinklers described herein must be
installed and maintained in compli-
ance with this document and with the
applicable standards of the National
Fire Protection Association, in addi-
tion to the standards of any authori-
ties having jurisdiction. Failure to do so
may impair the performance of these
devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
with any questions.

The Series RFII Concealed Pendent
Sprinklers are only listed and approved
with the Series RFII Concealed Cover
Plates having a factory applied finish.
NOTICE
Do not use the Series RFII in applica-
tions where the air pressure above
the ceiling is greater than that be-
low. Down drafts through the Sprin-
kler/Support Cup Assembly can delay
sprinkler operation in a fire situation.
Operation
When exposed to heat from a re, the
Cover Plate, normally soldered to the
Retainer at three points, falls away to
expose the Sprinkler/Support Cup
Assembly.
The Deector—supported by the
Guide Pins—then drops down to its
operational position.

Installation
The TYCO Series RFII must be in-
stalled in accordance with the follow-
ing instructions.
NOTICE
Do not install any bulb-type sprinkler if
the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bub-
ble should be present. The diameter
of the air bubble is approximately 1/16
inch (1,6 mm) for the 155°F/68°C and
3/32 inch (2,4 mm) for the 200°F/93°C
temperature ratings.
Obtain a 1/2 inch NPT sprinkler joint
by applying a minimum to maximum
torque of 7 to 14 ft.-lbs. (9,5 to 19,0
Nm). Higher levels of torque can dis-
tort the sprinkler Inlet with consequent
leakage or impairment of the sprinkler.
Do not attempt to compensate for in-
sufficient adjustment in the Sprinkler
by under- or over-tightening the Sprin-
kler/Support Cup Assembly. Re-adjust
the position of the sprinkler fitting to
suit.
Step 1. Install the sprinkler only in the
pendent position with the center-line
of the sprinkler perpendicular to the
mounting surface.
Step 2. Remove the Protective Cap.
Step 3. With pipe thread sealant ap-
plied to the pipe threads, hand-tighten
the sprinkler into the sprinkler tting.
Step 4. Wrench-tighten the sprinkler
using only the RFII Sprinkler Wrench.
(Refer to Figure 3.) Apply the RFII
Sprinkler Wrench to the Sprinkler as
shown in Figure 3.
Step 5. Replace the Protective Cap
by pushing it upwards until it bottoms
out against the Support Cup. (Refer
to Figure 4.) The Protective Cap helps
prevent damage to the Deector and
Arms during ceiling installation and/or
nish. You can also use the Protective
Cap to locate the center of the clear-
ance hole by gently pushing the ceiling
material up against the center point of
the Protective Cap.
NOTICE
As long as the Protective Cap remains
in place, the system is considered
“Out of Service”.
Step 6. After the ceiling has been com-
pleted with the 2-1/2 inch (63,5 mm) di-
ameter clearance hole and in prepa-
ration for installing the Cover Plate/
Retainer Assembly, remove and dis-
DBSEUIF1SPUFDUJWF$BQ7FSJGZUIBUUIFDeector moves up and down freely.
If the Sprinkler is damaged and the
Deector does not move up and down
freely, replace the entire Sprinkler.
Do not attempt to modify or repair a
damaged sprinkler.
Step 7. When installing an Air and Dust
4FBMSFGFSUP'JHVSFPUIFSXJTFQSP-
ceed to Step 8. To attach the Air and
Dust Seal, verify the angle of the out-
side edge of the seal is oriented ac-
cording to Figure 5. Start the edge of
the Retainer in the grooved slot of the
Air and Dust Seal and continue around
the retainer until the entire Air and Dust
Seal is engaged.
Step 8. Screw on the Cover Plate/
Retainer Assembly until the Retainer
(shown in Figure 2) or the Air and Dust
Seal (shown in Figure 5) contacts the
ceiling. Do not continue to screw on
the Cover Plate/Retainer Assembly
so that it lifts a ceiling panel out of its
normal position. If you cannot engage
the Cover Plate/Retainer Assembly
with the Support Cup or you cannot
engage the Cover Plate/Retainer As-
sembly sufciently to contact the ceil-
ing, you must reposition the Sprinkler
Fitting.
Care and
Maintenance
The TYCO Series RFII must be
maintained and serviced in accordance
with the following instructions.
NOTICE
Before closing a fire protection sys-
tem main control valve for maintenance
work on the fire protection system that
it controls, obtain permission to shut
down the affected fire protection sys-
tem from the proper authorities and no-
tify all personnel who may be affected
by this action.
Absence of the Cover Plate/Retainer
Assembly can delay sprinkler opera-
tion in a re situation.
When properly installed, there is a
nominal 3/32 inch (2,4 mm) air gap be-
tween the lip of the Cover Plate and the
ceiling, as shown in Figure 2.
This air gap is necessary for proper
operation of the sprinkler. If the ceil-
ing requires repainting after sprinkler
installation, ensure that the new paint
does not seal off any of the air gap.
Do not pull the Cover Plate relative to
the Enclosure. Separation may result.
Replace sprinklers that:
rare leaking or exhibiting visible signs
of corrosion.
rwere modied or over-heated.
Never paint, plate, coat, or otherwise
alter automatic sprinklers after they
leave the factory. Never repaint facto-
ry-painted Cover Plates. If necessary,
replace them with factory-painted
units. Non-factory applied paint can
adversely delay or prevent sprinkler
operation in the event of a re.
Exercise care to avoid damage to
sprinklers before, during, and after in-
stallation. Replace sprinklers damaged
by dropping, striking, wrench twisting,
wrench slipping, or the like. Also, re-
place any sprinkler that has a cracked
bulb or that has lost liquid from its
bulb. (Refer to the Installation section.)
If you must remove a sprinkler, do not
reinstall it or a replacement without re-
installing the Cover Plate/Retainer As-
sembly. If a Cover Plate/Retainer As-
sembly becomes dislodged during
service, replace it immediately.
Responsibility lies with sprinkler own-
ers for the inspection, testing, and
maintenance of their re protection
system and devices in compliance
with this document, as well as with the
applicable standards of the National
Fire Protection Association (for exam-
ple, NFPA 25), in addition to the stan-
dards of any other authorities having
jurisdiction. Contact the installing con-
tractor or sprinkler manufacturer re-
garding any questions.
Automatic sprinkler systems should be
inspected, tested, and maintained by a
qualied Inspection Service in accor-
dance with local requirements and/or
national code.
