Reliable has had a SW for EH occupancies for years, and I've looked at several projects over the years and it didn't seem to work out for any of them- but its available.
Also, I believe TFP has a OH HSW, at least 5 or 6 years ago we used some of them. glc -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Monday, January 05, 2009 1:02 PM To: [email protected] Subject: RE: Sidewall Sprinklers Guess all that would be just peachy if the mfgr listing stated that it's head was listed for such applications. I've often wished for an OH or even EH listed sidewall for similar reasons. But apparently the mfgrs. don't intend for them to be used for more than LH occupancies in most cases. Craig L.

A sidewall (or extended coverage sidewall at that) would keep your pipe out of the no hang zone where uprights (or extended coverage uprights) won't permit. Inaccessible areas. Rather than paying for scaffolding to get you over furniture/storage, why not install a sidewall where ladders/lifts can be used. Granted one can install sidewalls as mentioned above with the installation of a soffit/lintel. But why install the soffit if it is not truly necessary...like the overhead door scenario. And there is the infamous low clearance areas above compact shelving. The idea is being pushed around to install sidewalls where less than 18" clearance is being maintained. It has been presented that sidewalls can develop a spray pattern with less clearance than an upright/pendent. It appears the use of exposed sidewalls is developing...that is if listings permit.
