Series TY-FRL – 5.6 and 8.0 K-factor
Upright and Pendent Intermediate Level Sprinklers
Quick Response
General
Description
TYCO Series TY-FRL 5.6K and 8.0K
Quick Response Upright and Pendent
Intermediate Level Sprinklers are automatic sprinklers of the quick response
solder type. They are standard spray
sprinklers intended for use in fire sprinkler systems designed in accordance
with the standard installation rules
recognized by the applicable listing
or approval agency (e.g., UL Listing is
based on NFPA requirements). Both
the Pendent and Upright Sprinklers
produce a hemispherical water distribution pattern below the deflector.
Intermediate level sprinklers are primarily designed for use in rack storage
sprinkler systems where their thermally
sensitive elements must be shielded
from the water spray of higher elevation sprinklers that could operate
earlier during a fire. Intermediate level
sprinklers are also used in other applications such as beneath open gridded
catwalks.
IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and installation of sprinkler systems and components. Improper handling and
installation can permanently damage
a sprinkler system or its components and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.
NOTICE
The Series TY-FRL Sprinklers
described herein must be installed
and maintained in compliance with this
document, as well as with the applicable standards of the National Fire Protection Association (NFPA), in addition
to the standards of any other authorities having jurisdiction. Failure to do so
may impair the performance of these
devices.
The owner is responsible for maintaining their fire protection system
and devices in proper operating condition. Contact the installing contractor or product manufacturer with any
questions.

Operation
The fusible link (heat collector) assembly is comprised of two halves that
are joined together by a thin layer of
solder. When the rated temperature is
reached, the solder melts and the two
link halves separate, allowing the sprinkler to operate.
