Protect glass and your design

At-A-GlanceThe TYCO® Model CWS Window Sprinkler is a specific application sprinkler that is a cost-effective alternative to fire-rated glass. The sprinkler discharges an even coat of water when activated, which cools the window to help prevent shattering in a fire event.

The flat-plate concealed design houses the sprinkler above the ceiling and the cover plate is available in a variety of colors and finishes, as well as in custom, factory-painted colors. This solution offers the cost-saving and aesthetic benefits of using non-fire-rated glass, while also providing an effective fire protection solution that blends into the ceiling.

This sprinkler is part of a full window sprinkler line that includes horizontal sidewall and pendent models. It also joins the TYCO® family of aesthetic fire sprinklers, including commercial flat-plate concealed models.

Always refer to the Technical Data Sheet (TFP621 for Model CWS and TFP620 for Model WS) for complete description of all Listing criteria, design parameters, installation instructions, care and maintenance guidelines.
