Mark - I haven't had to deal with this section before, but I can see the ambiguity. It seems unclear if they are talking about the area of a warehouse sprinkler system or the actual size of a warehouse fire area (i.e. construction of the warehouse vs construction of the sprinkler system).
But I'll go out on a limb and suggest that they are discussing the size limitation of the warehouse fire areas. I.e., if you have a warehouse greater than 60,000 sq.ft., then you need to add a fire separation wall to create areas of less than 60,000 sq.ft. As an alternative, you can go up to 120,000 sq.ft. in the warehouse fire area if you follow the guidelines mentioned: increase sprinkler system design areas; provide enough isolation valves on the underground loop around the warehouse (as applicable); and provide a secondary fire pump if one pump is required. Of course, the third interpretation is that you cannot have more than 60,000 sq.ft. of warehouse in one building. The exception being that you can have 120,000 sq.ft. max. if you follow the guidelines above. But I don't think that's the intent. Mark A.

I'm having a hard time picturing how this all goes together. Also any hints on distance or arrangement would be helpful. Thanks Todd Todd G.
