Model CWS Specific Application
Concealed Pendent Vertical Sidewall
Window Sprinkler 5.6 K-factor
General
Description
The TYCO Model CWS Specific Appli-
cation Concealed Pendent Vertical
Sidewall Window Sprinkler is a fast
response, solder-link type sprinkler
which delivers water to window glazing
in a horizontal pattern.
This sprinkler is the first concealed
window sprinkler to be specifically
Listed to provide complete wetting and
coverage for heat strengthened, tem-
pered, or ceramic glass windows using
closed sprinklers. As part of the testing,
the gas flow required to achieve the
time/temperature relationship speci-
fied in ASTM E119 was established in
a test furnace without sprinkler pro-
tection. A window assembly protected
with the Model CWS Window Sprinkler
was then installed in the test furnace,
and the same gas flow conditions were
maintained for a two-hour test period.
No cracking or visible damage to the
window was permitted during the test
period.
The success of the Model CWS Window
Sprinkler is based on its fast response
thermal sensitivity and on its specially
designed deflector which ensures the
spray pattern wets the entire surface
of the window.
Based on successful testing, the Model
CWS Window Sprinkler can be used
as interior protection for windows or
glazing in a sprinklered building or
non-sprinklered building in accordance
