Model TY-QRF — 5.6 K-factor
Flush Pendent Sprinklers
Quick Response, Standard Coverage
General
Description
The TYCO Model TY-QRF, 5.6 K-factor,
Flush Pendent Sprinklers described
in this data sheet are quick response
- standard coverage decorative fus-
ible solder type sprinklers. They are
designed for use in commercial light
and ordinary hazard occupancies such
as offices and restaurants. When aes-
thetics is the major consideration, the
TY-QRF should be your first choice.
The TY-QRF features a separable
escutcheon providing 3/8 inch (9,5
mm) vertical adjustment. This adjust-
ment reduces the accuracy to which
the fixed pipe drops to the sprinklers
must be cut to help assure a perfect fit
installation.
NOTICE
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
tion, in addition to the standards of
any authorities having jurisdiction.
Failure to do so may impair the perfor-
mance 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.
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.

Operation
The sprinkler assembly contains a
small fusible solder element. When
exposed to sufficient heat from a fire,
the solder melts and enables the inter-
nal 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.

Design
Criteria
The TYCO Model TY-QRF, 5.6 K-factor,
Flush Pendent Sprinklers are intended
for fire protection systems designed
in accordance with the standard in-
stallation rules recognized by the ap-
plicable 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 corrosive agents such as flux,
other products that contain chloride
ions described, whether applied in-
ternally 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, op-
erate unexpectedly, 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 com-
ply 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 copper piping must be installed
in conformance with all applicable
TFP190
