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 spay of higher
elevation sprinklers which could oper-
ate earlier during a fire. Intermediate
Level Sprinklers are also used in 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
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 corrosion resistant coatings
for any given corrosive environment.
The effects of ambient temperature,
concentration of chemicals, and
gas/chemical velocity, should be con-
sidered, 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 integrity of these devices.
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
relative to any questions.
