Description
The Series TY-FRB, 5.6 K-factor Up-
right and Pendent Intermediate Level
Sprinklers described in this data sheet
are automatic sprinklers of the “quick
response” 3 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 Up-
right and Pendent 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.
For additional Series TY-FRB Sprin-
kler information, see Technical Data
Sheet TFP172. 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.
