Now all you need to do is show that there is enough need for this to have UL and FM develop a standard test for this installation, then convince the MFG's that the demand for this installation is great enough for them to spend 100's of thousands of $ to get the testing and listing done.(If each of them tried to list just 3 HSW heads, that would be over a million $. Takes a lot of HSW in "Space" installations to recover that kind of investment. Also I heard something about an economic down turn in the economy, where money is hard to get. That could just slow things down for several years. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

In other words, the sprinkler is either 9' away or 10' away from the fire. This leads one to believe that it would be possible to have an exposed HSW listed for a 10' throw for at least standard response, maybe quick response. Note, that if a 'recessed' or even 'concealed' pendent can get a listing at 9' or 10' away from the fire, you would think an exposed sidewall 4'-6" below the ceiling could receive a listing. Especially since 4"-6" below the ceiling is more ideal for a quick activation time than a recessed pendent.
