Why is there a "partial stairwell"?    Is it classified as required exit stair 
or a convenience stair?

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?
