Series TY-B — 5.6 and 8.0 K-factor
Upright and Pendent Intermediate Level Sprinklers
Standard Response
General
Description
The Series TY-B, 5.6 and 8.0 K-fac-
tor Upright and Pendent Intermediate
Level Sprinklers 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 sprin-
kler 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 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.
Corrosion resistant coatings, where
applicable, are utilized to extend the life
of copper alloy sprinklers beyond that
which would otherwise be obtained
when exposed to corrosive atmo-
spheres. Although corrosion resistant
coated sprinklers have passed the
standard corrosion tests of the appli-
cable approval agencies, the testing is
not representative of all possible cor-

Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

rosive atmospheres. Consequently,
it is recommended that the end user
be consulted with respect to the suit-
ability of these coatings for any given
corrosive environment. The effects of
ambient temperature, concentration of
chemicals, and gas/chemical velocity,
should be considered, as a minimum,
along with the corrosive nature of the
chemical to which the sprinklers will be
exposed.
NOTICE
The Series TY-B Sprinklers described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association, in addition to the stan-
dards of any other authorities having
jurisdiction. Failure to do so may impair
the performance of these devices.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted with
any questions.
