General
Description
The Central Model WS, 5.6 K-factor,
Pendent Vertical Sidewall and Horizon-
tal Sidewall, Specific Application
Window Sprinklers are quick response
glass bulb type spray sprinklers.
These sprinklers are the first sprinklers
ever to be specifically Listed to provide
protection for heat strengthened or
tempered glass windows using closed
sprinklers. As part of the testing, the
gas flow required to achieve the time/
temperature relationship specified in
ASTM E119 was established in a test
furnace without sprinkler protection. A
Window assembly protected with Model
WS Specific Application Window
Sprinklers was then installed in the test
furnace and the same gas flow condi-
tions were maintained for a two hour
test period. No cracking or visible
damage to the window was permitted
during the test period (even when a
hose stream was directed at the window).
The success of the Model WS Specific
Application Window Sprinkler is based
on its specially designed deflector, that
ensures that the spray pattern wets the
entire surface of the window, and its
fast response thermal sensitivity.
Based on this successful testing, the
Model WS Specific Application Window
Sprinkler can be used as interior
protection of windows or glazing in a
sprinklered building or non sprinklered
building. Also, the Model WS Specific
Application Window Sprinkler can be used
as a open sprinkler for "Outside Sprinkler
Protection against Exposure Fire", using
the design requirements of NFPA.
As with any specific application
sprinkler, the installation instructions
included in this data sheet must be
preciseley followed. National Evalua-
tion Service Inc. (NES), ICBO Evalua-
tion Service, Inc. (ICBO ES), and
Underwriters Labratories of Canada
(ULC) guidelines apply, consult the
specific approval report.
TM
Operation: The glass bulb contains a
fluid which expands when exposed to
heat. When the rated temperature is
reached, the fluid expands sufficiently to
shatter the glass bulb, which then
allows the sprinkler to activate & flow
water.
WARNING
The Model WS Specific Application
Window Sprinklers described herein
must be installed & maintained in
compliance with this document, as well
as with the applicable standards of the
National Fire Protection Association, in
addition to the standards of any other
authorities having jurisdiction. Failure to
do so may impair the integrity of these
devices.
The owner is responsible for
maintaining their fire protection system
and devices in proper operating
condition. The installing contractor or
sprinkler manufacturer should be
contacted relative to any questions.
