Series TY-FRB — 5.6 K-factor
Upright and Pendent Intermediate Level Sprinklers
Quick Response
General
Description
The Series TY-FRB, 5.6 K-factor Upright 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 systems 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 Upright and Pendent Sprinklers produce
a hemispherical water distribution pattern below the deflector.
Intermediate Level Sprinklers are primarily designed for use in rack storage sprinkler systems where their
thermally sensitive elements must be
shielded from the water spray of higher elevation sprinklers that could operate earlier during a fire. Intermediate
Level Sprinklers are also used in other applications such as beneath open
gridded catwalks.
For additional Series TY-FRB Sprinkler information, see Technical Data
Sheet TFP172. For additional Guard
and Shield information, see Technical
Data Sheet TFP780.

fluid expands sufficiently to shatter
the glass bulb, allowing the sprinkler
to activate and water to flow.
