IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and in-
stallation can permanently damage
a sprinkler system or its components
and cause the sprinkler to fail to
operate in a fire situation or cause it
to operate prematurely.
General
Description
The Tyco®Series RFII Quick Response
(3 mm bulb) & Standard Response (5
mm bulb), 5.6 K-Factor, “Royal Flush
II” Concealed Pendent Sprinklers are
decorative sprinklers featuring a flat
cover plate designed to conceal the
sprinkler. It is the best choice for archi-
tecturally sensitive areas such as ho-
tel lobbies, office buildings, churches,
and restaurants.
Each unit includes a Cover Plate As-
sembly that conceals the sprinkler op-
erating components above the ceiling.
The separable two-piece design of the
Cover Plate and Support Cup Assem-
blies allows installation of the sprin-
klers 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 suspend-
ed ceiling panels for access to building
service equipment without having to
first shut down the fire protection sys-
tem and remove sprinklers.
Also, the separable two-piece design
of the Sprinkler provides for 1/2 inch
(12,7 mm) of vertical adjustment, to
provide a measure of flexibility with re-
gard to which the length of fixed pipe
drops to the sprinklers must be cut.
The Series RFII Sprinklers are shipped
with a Disposable Protective Cap. The
Protective Cap is temporarily removed
for installation, and then it can be re-
placed to help protect the sprinkler
while the ceiling is being installed or
finished. The tip of the Protective Cap
can also be used to mark the center
of the ceiling hole into plaster board,
ceiling tiles, etc. by gently pushing the
ceiling product against the Protec-
tive Cap. When the ceiling installation
is complete the Protective Cap is re-
moved and the Cover Plate Assembly
installed.
As an option, the Series RFII Standard
Response (5 mm bulb) “Royal Flush II”
Concealed Pendent Sprinklers may be
fitted with a silicone Air and Dust Seal
(Ref. Fig. 5). The Air and Dust Seal is
intended for sensitive areas where it
is desirable to stop air and dust travel
through the cover plate from the area
above the ceiling.
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, 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 de-
vices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
with any questions.

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 Assembly.
At this point the Deflector supported
by the Guide Pins 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

The Series RFII Concealed Pendent
Sprinklers are only listed and approved
with the Series RFII Concealed Cover
Plates having a factory applied finish.
The Series RFII must not be used in
applications where the air pressure
above the ceiling is greater than
that below. Down drafts through the
Support Cup could delay sprinkler
operation in a fire situation.
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.
A 1/2 inch NPT sprinkler joint should
be obtained with a minimum to max-
imum torque of 7 to 14 ft.lbs. (9,5 to
19,0 Nm). Higher levels of torque may
distort the sprinkler inlet with conse-
quent leakage or impairment of the
sprinkler.
Do not attempt to compensate for in-
sufficient adjustment in the Sprinkler
Assembly by under-or over-tightening
the Sprinkler/Support Cup Assembly.
Readjust the position of the sprinkler
fitting to suit.
Step 1. The sprinkler must only be in-
stalled in the pendent position and
with the centerline of the sprinkler per-
pendicular 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 fitting.
Step 4. Wrench tighten the sprinkler
using only the RFII Sprinkler Wrench
(Ref. Figure 3). The RFII Sprinkler
Wrench is to be applied to the Sprin-
kler as shown in Figure 3.
Step 5. Replace the Protective Cap
(Ref. Figure 4) by pushing it upwards
until it bottoms out against the Sup-
port 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 Pro-
tective Cap.
NOTIce
As long as the Protective Cap remains
in place, the system is considered to
be “Out of Service”.

Step 6. After the ceiling has been
completed with the 2-1/2 inch (63,5
mm) diameter clearance hole and in
preparation for installing the Cover
Plate Assembly, remove and discard
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 Sprin-
kler assembly. Do not attempt to mod-
ify or repair a damaged sprinkler.
Step 7. When installing an Air and
Dust Seal, refer to 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 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/Re-
tainer Assembly until the Retainer Fig-
ure 2 (or Air and Dust Seal -Figure 5)
contacts with the ceiling. Do not con-
tinue to screw on the Cover Plate/Re-
tainer Assembly such that it lifts a ceil-
ing panel out of its normal position. If
the Cover Plate/Retainer Assembly
cannot be engaged with the Support
Cup or the Cover Plate/Retainer As-
sembly cannot be engaged sufficiently
to contact the ceiling, the Sprinkler Fit-
ting must be repositioned.
Care and
Maintenance
The Tyco®Series RFII must be
maintained and serviced in accordance
with the following instructions:
NOTIce
Absence of the Cover Plate Assembly
may delay sprinkler operation in a fire
situation.
When properly installed, there is a nom-
inal 3/32 inch (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 is to be repaint-
ed after the installation of the Sprinkler,
care must be exercised to ensure that
the new paint does NOT seal off any of
the air gap.
Factory painted Cover Plates MUST
NOT be repainted. They should be re-
placed, if necessary, by factory painted
units. Non-factory applied paint may
adversely delay or prevent sprinkler
operation in the event of a fire.
Do not pull the Cover Plate relative to
the Enclosure. Separation may result.
Before closing a fire protection sys-
tem main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated or otherwise
altered after leaving the factory. Modi-
fied or over heated sprinklers must be
replaced.
Care must be exercised to avoid dam-
age to the sprinklers -before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be re-
placed. Also, replace any sprinkler that
has a cracked bulb or that has lost
liquid from its bulb. (Ref. Installation
Section).
If a sprinkler must be removed, do not
reinstall it or a replacement without
reinstalling the Cover Plate Assembly.
If a Cover Plate Assembly becomes
dislodged during service, replace it
immediately.
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and devic-
es in compliance with this document,
as well as with the applicable stan-
dards of the National Fire Protection
Association (e.g., NFPA 25), in addition
to the standards of any other authori-
ties having jurisdiction. The installing
contractor or sprinkler manufacturer
should be contacted relative to 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.
