TYCO Model CWS Concealed Window Sprinkler by Johnson Controls
TYCO Model CWS Concealed Window Sprinkler provides an alternative to a two-hour fire-resistance-rated glazing assembly. Sprinkler is specifically listed to provide complete wetting and coverage for heat strengthened, tempered, or ceramic glass windows using closed sprinklers. The 5.6 K-factor CWS discharges an even coat of water when activated, which cools the window to help prevent shattering during a fire event.
