Depending on the conditions of the project in regards to an underwriter or other AHJ requirement, contents such as piping, wiring, HVAC equipment, ducting, etc. could be combustible and drive an underwriter to require above ceiling protection due to the combustible loading of the contents, not the construction of the building itself.
Any fuel fired equipment above the ceiling? Potential junk storage space? Craig L.

And maybe the contract dwgs showed above and below, referred to it as under/over, and maybe this is a plumber who doesn't know you don't need uprights in noncombustible spaces, maybe the AE doesn't care, they're on the docs and its plan/spec, or ??? glc -----Original Message----- From: sprinklerforum-boun...@firesprinkler.org [mailto:sprinklerforum-boun...@firesprinkler.org] On Behalf Of James Zimmerman Sent: Thursday, February 18, 2010 11:37 AM To: sprinklerforum@firesprinkler.org Subject: Under/Over Sprinkler Has anyone seen/used the term under/over sprinkler on a set plans? Someone in my office has a set of plans where the contractor called out the sprinklers as under/over sprinklers. At first I thought maybe it was describing pendant sprinklers below the ceiling and upright above, protecting a combustible concealed space. However, the construction noncombustible (concrete floors and gyp ceilings). The only details on the plans are for a concealed sprinkler on a return bend and a detail for an upright sprinkler. I'm sure they will be contacting the contractor about the term but I was just curious if anyone here had seen the term.
