Upright and Pendent Intermediate Level Sprinklers
Standard Response
General
Description
The Series TY-B, 5.6 K-factor Upright
and Pendent Intermediate Level Sprin-
klers described in this data sheet are
automatic sprinklers of the "standard
response" 5 mm frangible bulb type.
They are "standard spray" sprinklers
intended for use in fire sprinkler sys-
tems 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 Pen-
dent and Upright Sprinklers produce
a hemispherical water distribution pat-
tern below the deflector.
Intermediate Level Sprinklers are pri-
marily designed for use in rack stor-
age sprinkler systems where their
thermally sensitive elements must be
shielded from the water spray of high-
er elevation sprinklers that could op-
erate earlier during a fire. Intermediate
Level Sprinklers are also used in oth-
er applications such as beneath open
gridded catwalks.

TFP152. For additional Guard and
Shield information, see Technical Data
Sheet TFP780.

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, allowing the sprinkler
to activate and water to flow.
