Right again. The issue of a "water curtain" morphed into the 2-hour rating, which to my knowledge can only be achieved with a listed window sprinkler, i.e. Tyco WS.

The window sprinkler is a "Specific application sprinkler" installed in accordance with its listing only!!(Can't be used for openings, or escalators or mall atriums, unless these are fixed glass with mullions Horz. and vert. and spacing as per the listing.) A water curtain NFPA 13 2007 11.3.3.1 to 11.3.3.4 is a series of closely spaced sprinkler's with specific uses as defined in chapter 8.(Specifically 8.15.4.1 to 8.15.4.3 and 8.15.16.2, these are the only uses of water curtains allowed by 13) Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

A REALLY important aspect of using this sprinkler: it is only listed for fixed glazing.
