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-factor
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 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 ther-
mally 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 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 ob-
tained when exposed to corrosive at-
mospheres. Although corrosion resis-
tant coated sprinklers have passed the
IMPORTANT
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 in-
stallation 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.

standard corrosion tests of the appli-
cable approval agencies, the testing is
not representative of all possible cor-
rosive atmospheres. Consequently, it
is recommended that the end user be
consulted with respect to the suitability
of these coatings for any given corro-
sive environment. The effects of ambi-
ent 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.
WARNINGS
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
standards of any other authorities hav-
ing jurisdiction. Failure to do so may
impair the performance of these de-
vices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
with any questions.
