General
Description
The Series TY-B, 5.6 and 8.0 K-factor,
Upright and Pendent Sprinklers de-
scribed in this data sheet are standard
response - standard coverage, deco-
rative 5 mm glass bulb
type spray
sprinklers designed for use in light,
ordinary, or extra hazard, commercial
occupancies such as banks, hotels,
shopping malls, factories, refineries,
chemical plants, etc.
The recessed version of the Series
TY-B Pendent Sprinkler, where appli-
cable, is intended for use in areas with
a finished ceiling. It uses a two-piece
Style 10 (1/2 inch NPT) or Style 40 (3/4
inch NPT) Recessed Escutcheon. The
Recessed Escutcheon provides 1/2
inch (12,7 mm) of recessed adjust-
ment or up to 3/4 inch (19,1 mm) of
total adjustment from the flush pen-
dent position. The adjustment provided
by the Recessed Escutcheon reduces
the accuracy to which the fixed pipe
drops to the sprinklers must be cut.
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.
An intermediate level version of the
Series TY-B Pendent Sprinkler can be
obtained by utilizing the Series TY-B
Pendent Sprinkler in combination with
the Model S2 Shield.
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.
