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 (Ref. Figure 1C),
permitting water to flow.
General
Description
TYCO Model TY-QRF 5.6K Quick
Response, Standard Coverage, Flush
Pendent Sprinklers are decorative,
fusible 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 separa-
ble escutcheon providing 3/8 in.
(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 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 Associa-
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 main-
taining their fire protection system

dition. Contact the installing contrac-
tor or product manufacturer with any

Design
Criteria
TYCO Model TY-QRF 5.6K Quick
Response, Standard Coverage, Flush
Pendent Sprinklers are intended for
fire protection systems designed in
accordance with the standard instal-
lation rules recognized by the appli-
cable listing or approval agency
(e.g., UL Listing is based on NFPA 13

Precautionary Warnings for
Corrosive 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 chlo-
ride ions described, whether applied
internally or externally to the sprin-
kler system, may result in corrosion
of the sprinkler head, or stress corro-
sion cracking, which in turn may cause
the sprinklers heads to develop leaks,
operate 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 comply
fully with NFPA 13 and 25, ASTM B813,
ASTM B828 and Copper Development
Association (CDA).
