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 sprinklers
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,
Model K17-231 Pendent and Upright
Sprinklers are expanding beyond the
current listings/approvals. For infor-
mation regarding research fire tests
which may be acceptable to an author-
ity having jurisdiction, please contact
the Technical Services Department.
NOTICE

Upright and Pendent Sprinklers

Operation
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and flow water.
