General
Description
The TYCO Model WS Specic
Application Window Sprinklers are fast
response, glass bulb-type spray sprin-
klers available in Horizontal Sidewall
and Pendent Vertical Sidewall models.
These sprinklers are the rst to be
specically Listed to provide complete
wetting and coverage for heat strength-
ened, tempered, or ceramic glass
windows using closed sprinklers.
As part of the testing, the gas ow
required to achieve the time/temper-
ature relationship specied in ASTM
E119 was established in a test furnace
without sprinkler protection. A window
assembly protected with the TYCO
Model WS Window Sprinklers was
then installed in the test furnace, and
the same gas ow conditions 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 Window
Sprinklers is based on their fast
response thermal sensitivity and on
their specially designed deectors that
ensure that the spray pattern wets the
entire surface of the window.
Based on successful testing, the
Model WS Window Sprinklers can be
used as interior protection of windows
or glazing in a sprinklered building or
non-sprinklered building in accordance
with Section 104 of the IBC (“Alternate
Materials, Design and Methods of
Construction and Equipment”). Also,
the Model WS Window Sprinklers
can be used as an open sprinkler for
“Outside Sprinkler Protection against
Exposure Fire”, using the design
requirements of NFPA.
As with any specic application sprin-
kler, the installation instructions
included in this data sheet must be
precisely followed. If there are addi-
tional local or jurisdictional installation
standards/codes for window sprinklers
on glazed window systems, this docu-
ment does not relieve the designer/
installer from these requirements.
Consult your local jurisdiction to verify
if or when these additional guidelines
must be followed.
