General
Description
The TYCO Series RFII, 5.6 K-fac-
tor, Royal Flush Concealed Pendent
Sprinklers, (TY3532), Quick Response,
Extended Coverage, Light Hazard
(ECLH) are decorative, 3 mm bulb-
type sprinklers featuring a flat cover
plate designed to conceal the sprinkler.
These sprinklers are optimal for archi-
tecturally 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 (e.g., NFPA 13). The
fast-response thermal sensitivity rating
of the Series RFII (TY3532) provides for
a quick response, extended coverage
(QREC) rating up to a 20 ft x 20 ft cov-
erage area.
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 sprin-
kler 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.
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 main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

Design
Criteria
The TYCO Series RFII, 5.6 K-factor,
Royal Flush Concealed Pendent Sprin-
klers (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
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 Concealed Pendent Sprin-
klers, (TY3532) must be installed in
accordance with this section.
General Instructions
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 bubble
should be present. The diameter 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) tempera-
ture ratings.
Obtain a 1/2 in. NPT sprinkler joint
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 centerline
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 5. Replace the Protective Cap by
pushing it upwards until it bottoms out
against the Support Cup. (Ref. Figure
4.)
The Protective Cap helps prevent
damage 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
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
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. Screw on the Cover Plate/
Retainer Assembly until its flange
makes contact with 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 sufficiently to
contact the ceiling, you must reposition
the Sprinkler Fitting.

Care and
Maintenance
The TYCO Series RFII, 5.6 K-factor,
Royal Flush Concealed Pendent Sprin-
klers, (TY3532) 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 protec-
tion 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 oper-
ation of the sprinkler. If the ceiling
requires 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-
tory-painted Cover Plates. If neces-
sary, replace them with factory-painted
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.
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 product
manufacturer with 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.
