The over under sprinkler may refer to the Old Style head, where around 60% is sprayed above and 40% is sprayed below.

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.
