Tyco K17-231 Manual

Model K17-231 — 16.8 K-factor
Upright and Pendent Sprinklers
Standard Response, Standard Coverage
General
Description
The TYCO 16.8 K-factor, Model
K17-231, Standard Response, Standard
Coverage, Upright and Pendent Sprin-
klers (Ref. Figure 1) are automatic sprin-
klers of the frangible bulb type. They
are "standard response spray sprin-
klers" which produce a hemispherical
water distribution pattern below the
deflector.
The 16.8 K-factor, K17-231 Sprinklers
were subjected to full scale, high-piled
storage, fire tests to qualify their use
in lieu of 8.0 or 11.2 K-Factor standard
spray sprinklers for the protection of
high-piled storage.
Higher flow rates can be achieved at
much lower pressures with the 16.8 K-
factor, K17-231 Sprinklers — making
their use highly advantageous in high
density applications, such as the pro-
tection of high-piled storage.
Applications for the 16.8 K-factor, Mod-
el K17-231 Pendent and Upright Sprin-
klers are expanding beyond the cur-
rent listings/approvals. For information
regarding research fire tests which may
be acceptable to an authority having ju-
risdiction, please contact the Technical
Services Department.
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling
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.
