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 stan-
dard response 5 mm frangible bulb
type. They are standard spray sprin-
klers intended for use in fire sprinkler
systems designed in accordance with
the standard installation rules rec-
ognized by the applicable Listing or
Approval agency (e.g., UL Listing is
based on NFPA requirements). Both
the Pendent and Upright Sprinklers
produce a hemispherical water distri-
bution pattern below the deflector.
Intermediate Level Sprinklers are pri-
marily designed for use in rack storage
sprinkler systems where their thermally
sensitive elements must be shielded
from the water spray of higher ele-
vation sprinklers that could operate
earlier during a fire. Intermediate Level
Sprinklers are also used in other appli-
cations such as beneath open gridded
catwalks.

Operation

The glass bulb contains a fluid which
½ 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.
