General
Description
The Series TY-B, 5.6 K-factor, Horizon-
tal and Vertical Sidewall 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 and
ordinary hazard, commercial occupan-
cies such as banks, hotels, shopping
malls, etc. They are designed for instal-
lation along a wall or the side of a beam
and just beneath a smooth ceiling.
Sidewall sprinklers are commonly
used instead of pendent or upright
sprinklers because of aesthetics or
building construction considerations,
where piping across the ceiling is not
desirable.
The recessed version of the Series
TY-B Horizontal Sidewall Sprinkler is
intended for use in areas with a fin-
ished wall. It uses a two-piece Style 10
Recessed Escutcheon. The Recessed
Escutcheon provides 1/2 inch (12,7
mm) of recessed adjustment or up to
3/4 inch (19,1 mm) of total adjustment
from the flush sidewall position. The
adjustment provided by the Recessed
Escutcheon reduces the accuracy to
which the fixed pipe nipples 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.
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.
