So it's an offset stair, correct? In other words, it doesn't just go from an upper floor down 3 levels to a lobby, it stays in an exit passageway and you go horizontally on the transfer floor to a different stairwell for the rest of the trip down to exit discharge, is that right?

From: Sprinklerforum [mailto:[email protected]] On Behalf Of Jerry Van Kolken Sent: Monday, April 30, 2018 3:04 PM To: [email protected]<mailto:[email protected]> Subject: Secondary Standpipe on Upper Levels I have a 12 story project with a partial stairwell on the top 3 floors. The AHJ is requiring a standpipe at this partial stairwell. My question is to I need to run another vertical feed from the pump on the first floor, or can I do a horizontal feed off the standpipe in the opposite stairwell on the upper level?
