Tyco TY-QRF User manual

General
Description
The Model TY-QRF, 5.6 K-factor, Flush
Pendent Sprinklers described in this
data sheet are quick response - stand-
ard coverage decorative fusible solder
type sprinklers. They are designed for
use in commercial light and ordinary
hazard occupancies such as offices
and restaurants. When aesthetics is
the major consideration, the TY-QRF
should be your first choice.
The TY-QRF features a separable es-
cutcheon providing 3/8 inch (9,5 mm)
vertical adjustment. This adjustment
reduces the accuracy to which the
fixed pipe drops to the sprinklers must
be cut to help assure a perfect fit instal-
lation.
WARNINGS
The Model TY-QRF Flush Pendent
Sprinklers described herein must be
installed and maintained in compli-
ance with this document, as well as
with the applicable standards of the
National Fire Protection Association,
in addition to the standards of any
other authorities having jurisdiction.
Failure to do so may impair the per-
formance 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
The sprinkler assembly contains a
small fusible solder element. When ex-
posed to sufficient heat from a fire, the
solder melts and enables the internal
components of the sprinkler to fall
away. At this point the sprinkler acti-
vates with the deflector dropping into
its operated position (Reference Fig-
ure 1C), permitting water to flow.

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 compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

Design
Criteria
The Model TY-QRF Flush Pendent
Sprinklers are intended for fire protec-
tion systems designed in accordance
with the standard installation rules rec-
ognized by the applicable Listing or
Approval agency (e.g., UL Listing is
based on NFPA 13 requirements).
Precautionary Warnings for Corro-
sive Environments. The Model
TY-QRF Flush Pendent Sprinklers
must be installed in a non-corrosive
environment. The improper use of cor-
rosive agents such as flux, other prod-
ucts that contain chloride ions de-
scribed, whether applied internally or
externally to the sprinkler system, may
result in corrosion of the sprinkler
head, or stress corrosion cracking,
which in turn may cause the sprinklers
heads to develop leaks, operate unex-
pectedly, or not operate properly.
Accordingly, it is essential that the
Model TY-QRF Flush Pendent Sprin-
klers be installed only by experienced
fire sprinkler engineers, who comply
fully with NFPA 13 and 25, ASTM
B813, ASTM B828 and Copper Devel-
opment Association (CDA).
Copper sprinkler system piping.
Any time copper piping is used in any
part of a fire sprinkler system, the cop-
per piping must be installed in confor-
mance with all applicable standards
and requirements for copper piping,
including: NFPA 13 and 25, ASTM
B813, ASTM B828, and Copper Devel-
opment Association (CDA). Any sol-
dering in any part of a sprinkler sys-
tem, either internally or externally,
must be done with use of only an
ASTM B 813 approved flux. Residual
fluxmustbethoroughlyREMOVED
from both the interior and exterior sur-
faces of the piping before installing the
sprinkler heads. The use of improper
flux, or the failure to thoroughly remove
proper flux, may result in corrosion of
the sprinkler head or stress cracking,
which in turn may cause the sprinklers
heads to develop leaks, operate unex-
pectedly, or not operate properly.
Installation
The Model TY-QRF (TY3261) Flush
Pendent Sprinklers must be installed
in accordance with the following in-
structions:
NOTES
The Protective Cap is to remain on the
sprinkler during installation until the
ceiling installation is complete. The
Protective Cap must be removed to
place the sprinkler in service.
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7
to 14 ft.lbs. (9,5 to 19,0 Nm). A maxi-
mum of 21 ft.lbs. (28,5 Nm) of torque
is to be used to install sprinklers.
Higher levels of torque may distort the
sprinkler inlet with consequent leak-
age or impairment of the sprinkler.
Do not attempt to compensate for in-
sufficient adjustment in an Escutcheon
Plate by under- or over-tightening the
Sprinkler. Readjust the position of the
sprinkler fitting to suit.
Each sprinkler must be inspected be-
fore installation. Do not use any sprin-
kler that exhibits any deformations or
cracks, including cracks on the protec-
tive cap.
Step 1. The Sprinkler must be installed
only in the pendent position and with
the Sprinkler waterway centerline per-
pendicular to the mounting surface.
Step 2. Install the sprinkler fitting so
that the distance from the face of the
fitting to the mounting surface will be
nominally 1-3/32 inches (27,8 mm) as
showninFigure1A.
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 Sprinkler Socket or
Wrench & Socket Combination (Ref.
Figure 2). The wrench recess of the
Socket is to be applied to the sprinkler
wrenching area (Ref. Figure 1A).
Step 5. Use the “ceiling level tolerance
limit” indicator on the Protective Cap to
check for proper installation height.
Relocate the sprinkler fitting as neces-
sary. If desired the Protective Cap may
also be used to locate the center of the
clearance hole by gently pushing the
ceiling material against the center
pointoftheCap.
Step 6. After the ceiling has been com-
pleted with the 2 inch (50 mm) diame-
ter clearance hole, use the Protective
Cap Removal Tool (Ref. Figure 3) to
remove the Protective Cap and then
push on the Escutcheon until its flange
just comes in contact with the ceiling.
Do not continue to push the Escutch-
eon such that it lifts a ceiling panel out
of its normal position. If the Escutch-
eon cannot be engaged with the Sprin-
kler, or the Escutcheon cannot be en-
gaged sufficiently to contact the
ceiling, relocate the sprinkler fitting as
necessary.

Care and
Maintenance
The Model TY-QRF must be main-
tained and serviced in accordance
with the following instructions:
NOTES
Absence of an Escutcheon Plate may
delay the time to sprinkler operation in
a fire situation.
Before closing a fire protection system
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 which are found to be leak-
ing or exhibiting visible signs of corro-
sion 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 - before, during, and after instal-
lation. Sprinklers damaged by drop-
ping, striking, wrench twist/slippage,
or the like, must be replaced.
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any other
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer should be contacted relative to
any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service in accordance with
local requirements and/or national
codes.
