General
Description
The TYCO Series RFII 5.6 K-factor,
“Royal Flush II” Concealed Pendent
Sprinklers Quick Response (3-mm
bulb) and Standard Response (5-mm
bulb), are decorative sprinklers fea-
turing a flat cover plate designed to
conceal the sprinkler. These sprinklers
are optimal for architecturally sensi-
tive areas such as hotel lobbies, office
buildings, 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 benefits:
• Allows installation of the sprinklers
and pressure testing of the fire pro-
tection system prior to installation of
a suspended ceiling or application of
the finish coating to a fixed ceiling.
• Permits the removal of suspended
ceiling panels for access to building
service equipment without having
to first shut down the fire protection
system and remove sprinklers.
• Provides for 1/2 in. (12,7 mm) of ver-
tical adjustment to allow a measure
of flexibility in determining the length
of fixed 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
installation or finish. 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 pushing
the ceiling product against the Pro-
tective Cap. When ceiling installa-
tion is complete, the Protective Cap is
removed 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
fitted with a silicone Air and Dust Seal.
See 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 compliance
with this document and with the appli-
cable standards of the NATIONAL FIRE
PROTECTION ASSOCIATION (NFPA),
in addition to the standards of any
authorities 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
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted with
any questions.

Design
Criteria
The TYCO Series RFII 5.6 K-factor,
“Royal Flush II” Concealed Pendent
Sprinklers are intended for fire protec-
tion systems designed in accordance
with the standard installation rules
recognized by the applicable Listing
or Approval agency; for example, UL
Listing is based on NFPA 13 and VdS
Approval is based on the CEA 4001.
For more information on LPCB and VdS
Approvals, contact Johnson Controls
at the following office:
Enschede, Netherlands
Telephone: 31-53-428-4444
Fax: 31-53-428-3377
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 below. Down
drafts through the Sprinkler/Support
Cup Assembly can delay sprinkler
operation in a fire situation.
Operation
When exposed to heat from a fire, the
Cover Plate, normally soldered to the
Retainer at three points, falls away to
expose the Sprinkler/Support Cup
Assembly.
The Deflector — supported by the
Guide Pins — then drops down to its
operational position.
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, activating the sprinkler and
allowing water to flow.
Installation
The TYCO Series RFII 5.6 K-factor,
“Royal Flush II” Concealed Pendent
Sprinklers must be installed in accor-
dance with this section.
General Instructions
Do not install any bulb-type sprin-
kler if the bulb is cracked or there is
a loss of liquid from the bulb. With the
sprinkler held horizontally, a small air
bubble should be present. The diam-
eter of the air bubble is approximately
1/16 in. (1,6 mm) for the 155°F (68°C)
and 3/32 in. (2,4 mm) for the 200°F
(93°C) temperature ratings.
A leak-tight 1/2 in. NPT sprinkler joint
should be obtained by applying a
minimum to maximum torque of 7 to
14 lb-ft (9,5 to 19,0 N·m). Higher levels
of torque can distort the sprinkler Inlet
with consequent leakage or impairment
of the sprinkler.
Do not attempt to compensate for
insufficient 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
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
fitting.
Step 4. Wrench-tighten the sprinkler
using only the RFII Sprinkler Wrench.
See Figure 3. Apply the RFII Sprinkler
Wrench to the Sprinkler as shown in
Figure 3.

B: 3/16 in. (4,8 mm) D: 1-3/4 to 2-1/4 in. (44,5 to 57,2 mm)
Step 5. Replace the Protective Cap by
pushing it upwards until it bottoms out
against the Support Cup. See Figure
4. The Protective Cap helps prevent
damage to the Deflector and Arms
during ceiling installation and/or finish.
You can also use the Protective Cap to
locate the center of the clearance hole
by gently pushing the ceiling material
up against the center point of the Pro-
tective 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
completed with the 2-1/2 in. (63,5 mm)
diameter clearance hole and in prep-
aration for installing the Cover Plate/
Retainer Assembly, remove and discard
the Protective Cap. Verify that the
Deflector moves up and down freely.
If the Sprinkler is damaged and the
Deflector 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
Seal, see Figure 5; otherwise, proceed
to Step 8. To attach the Air and Dust
Seal, verify the angle of the outside
edge of the seal is oriented accord-
ing 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 Assembly suf-
ficiently to contact the ceiling, you must
reposition the Sprinkler Fitting.

Care and
Maintenance
The TYCO Series RFII 5.6 K-factor,
“Royal Flush II” Concealed Pendent
Sprinklers must be maintained and
serviced in accordance with this
section.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system
that it controls, obtain permission to
shut down the affected fire protection
system from the proper authorities
and notify all personnel who may be
affected by this action.
Absence of the Cover Plate/Retainer
Assembly can delay sprinkler opera-
tion in a fire situation.
When properly installed, there is a
nominal 3/32 in. (2,4 mm) air gap
between 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 ceiling
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.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid
damage to the sprinklers - before,
during, and after installation. Sprin-
klers damaged by dropping, striking,
wrench twist/slippage, or the like, must
be replaced. Also, replace any sprinkler
that has a cracked bulb or that has lost
liquid from its bulb. See the Installation
Section.
Exercise care to avoid damage to sprin-
klers before, during, and after instal-
lation. Replace sprinklers damaged
by dropping, striking, wrench twist-
ing, wrench slipping, or the like. Also,
replace any sprinkler that has a cracked
bulb or that has lost liquid from its bulb.
See the Installation section.
If you must remove a sprinkler, do not
reinstall it or a replacement without
reinstalling the Cover Plate/Retainer
Assembly. If a Cover Plate/Retainer
Assembly becomes dislodged during
service, replace it immediately.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION, for example, NFPA 25,
in addition to the standards of any other
authorities having jurisdiction. Contact
the installing contractor or sprinkler
manufacturer regarding any questions.
Automatic sprinkler systems should be
inspected, tested, and maintained by a
qualified Inspection Service in accor-
dance with local requirements and/or
national code.
