Yeah, I was looking in an older version of NFPA 14. That figure in the new version really clears it up.

Look at the 2016 edition annex figure. The one in the 2013 edition is wrong.

From: Sprinklerforum [mailto:[email protected]] On Behalf Of Steve Leyton Sent: Tuesday, August 29, 2017 1:31 PM To: [email protected]<mailto:[email protected]> Subject: RE: Hose Valves at Horizontal Exits Each side is evaluated independently of the other, so in order to omit both valves you need two conforming stairs, one on each side of the fire area separation wall. Also, be sure to carefully review Fig. A.7.3.2.2.1 (NFPA 14, 2016 ed.) as it gives a clear illustration of the intent of this exception. If you have a stairwell standpipe connection that enables you to reach the entire floor on one side of a horizontal exit within the 130' threshold, then you can omit the valve on the OTHER side of the exit (the one in the adjacent fire area).

In order to omit hose connections from both sides of the horizontal exit, am I required to have two exit stairs (one in each fire area) located within 130 feet of the horizontal exit, reachable from both sides? Or is any one exit stairway within 130 feet of the horizontal exit OK? Kyle Montgomery [cid:[email protected]] Aero Automatic Sprinkler Co. 21605 N.
