Operation: The glass bulb contains a
fluid which expands when exposed to
heat. When the rated temperature is
reached, the fluid expands sufficiently to
shatter the glass bulb, which then allows
the sprinkler to activate & flow water.

General
Description
The Central Model Ultra K17, 16.8
K-Factor, Standard Response, Upright,
Specific Application Storage Sprinklers
are automatic sprinklers of the frangible
bulb type. They are "standard response
- spray sprinklers" which produce a
hemispherical water distribution pattern
below the deflector.
The Ultra K17 Specific Application
Storage Sprinklers are intended for use
in fire sprinkler systems designed in
accordance with the standard installa-
tion rules recognized by the applicable
Listing or Approval agency (e.g., UL
Listing is based on the requirements of
the National Fire Protection Associa-
tion), as well as in accordance with their
"specific application" listing/approvals.
The Ultra K17 Specific Application
Storage Sprinklers were subjected to
full scale, high-piled storage, fire tests to
qualify their use with reduced pressure
and design areas for the protection of
high-piled storage. The use of the
Ultra K17 Specific Application Storage
Sprinklers in some cases can subse-
quently reduce the design area and the
overall water demand of a sprinkler
system.
Applications for the Ultra K17 Specific
Application Storage Sprinklers are
expanding beyond the current "specific
application" listings/approvals. For
information regarding research fire tests
which may be acceptable to an
Authority Having Jurisdiction, please

ment.
