Tyco K17-231 Quick Start 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 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.
