General
Description
The Tyco®Series RFII, 5.6 K-factor,
Extended Coverage, Light Hazard
(ECLH) “Royal Flush” Concealed Pen-
dent Sprinklers are decorative, 3 mm
bulb-type sprinklers featuring a flat
cover plate designed to conceal the
sprinkler. These sprinklers are opti-
mal for architecturally sensitive areas
such as hotel lobbies, office buildings,
churches, and restaurants.
The Series RFII sprinklers are intended
for use in automatic sprinkler systems
designed in accordance with standard
installation rules (for example, NFPA
13). The fast-response thermal sensi-
tivity rating of the Series RFII (TY3532)
provides for a quick response, extend-
ed coverage (QREC) rating up to a
20 ft. x 20 ft. coverage area.
Each sprinkler includes a Cover Plate/
Retainer Assembly and a Sprinkler/
Support Cup Assembly. The separable,
two-piece assembly design provides
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 applica-
tion 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 inch (12,7 mm) of•
vertical adjustment to allow a mea-
sure 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 in-
stallation 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 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.
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
devices in proper operating condi-
tion. The installing contractor or sprin-
kler manufacturer should be contact-
ed with any questions.

Design
Criteria
The Tyco®Series RFII Concealed
Pendent Sprinklers (TY3532) are
UL and C-UL Listed for use in light
hazard occupancies, using the design
criteria in Table A, in addition to the
requirements specified in the current
NFPA 13 for extended coverage
pendent sprinklers.
The Series RFII Concealed Pendent
Sprinklers are only listed and approved
with the Series RFII Concealed Cover
Plates with a factory-applied finish.
NOTIce
Do not use the Series RFII in
applications 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 ex-
pands 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 must be installed
in accordance with the following
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 Sprin-
kler by under- or over-tightening
the Sprinkler/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 centerline
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 fitting.

Step 4. Wrench-tighten the sprinkler
using only the RFII Sprinkler Wrench
shown in Figure 3. Apply the RFII
Sprinkler Wrench to the Sprinkler as
shown in the figure.
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 dam-
age to the Deflector and Frame Arms
when installing or finishing the ceiling.
You can also use it to locate the center
of the clearance hole by gently push-
ing 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)
diameter clearance hole and in prepa-
ration for installing the Cover Plate/Re-
tainer Assembly, remove and discard
the Protective Cap.
Verify that the Deflector moves up and
down freely. If the Sprinkler is dam-
aged 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. Screw on the Cover Plate/Re-
tainer Assembly until its flange makes
contact with the ceiling. Do not con-
tinue to screw on the Cover Plate/Re-
tainer Assembly so that it lifts a ceiling
panel out of its normal position. If you
cannot engage the Cover Plate/Re-
tainer Assembly with the Support Cup
or you cannot engage the Cover Plate/
Retainer Assembly sufficiently to con-
tact the ceiling, 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 system
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
notify all personnel who may be affect-
ed 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 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 oper-
ation of the sprinkler. If the ceiling re-
quires repainting after sprinkler instal-
lation, 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 are leaking or
exhibiting visible signs of corrosion.
Never repaint, plate, coat, or otherwise
alter automatic sprinklers after they
leave the factory. Never repaint fac-Never repaint fac-
tory-painted Cover Plates. If neces-
sary, replace them with factory-paint-
ed units. Non-factory applied paint can
adversely delay or prevent sprinkler
operation in the event of a fire.
Replace modified or over-heated
sprinklers.
Exercise care to avoid damage to
the sprinklers before, during, and
after installation. Replace sprinklers
damaged by dropping, striking, wrench
twisting, wrench slipping, or the like.
Also, replace 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
reinstalling the Cover Plate/Retainer
Assembly. If a Cover Plate/Retainer
Assembly becomes dislodged during
service, replace it immediately.
Responsibility lies with the owner 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
accordance with local requirements
and/or national code.
