The TYCO Model WS Specific Appli
cation Window Sprinklers are fast
response, glass bulb-type spray sprin
klers available in Horizontal Sidewall
and Pendent Vertical Sidewall models.
These sprinklers are the first to be
specifically Listed to provide com
plete wetting and coverage for heat
strengthened, tempered, or ceramic
glass windows using closed sprin
klers. 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 the
TYCO Model WS Window Sprinklers
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, even when a hose stream was
directed at the window.
Note: Some sprinkler head may or may not have Teflon tape applied. The heads have never been installed.
