Mark, It's not mandatory to interconnect the different fire dept. connections. However if you don't interconnect them it is very difficult for the fire dept. to know the building area that the specific fire dept. connection serves, especially in a fire condition where things are happening quickly. Paragraph 8.17.2.4.5 refers to a partially sprinklered building so the fire department is aware of that and they can fight the fire accordingly. If you don't want to interconnect the fire dept. connections the best thing to do is ask the AHJ and get their input.

The case I have in mind is a large warehouse (200,000 sq ft) with risers at opposite ends as was commonly done in the past. Is there a code requirement or good practice recommendation? NFPA 13-2010 paragraph 8.17.2.4.5 states "*Where a fire department connection services only a portion of a building, a sign shall be attached indicating the portions of the building served*." Is section intended to apply to a partially sprinklered buildings to advise that the entire building is not protected? Or is it intended to permit multiple FDCs as long as you clearly indicated which portion of the building it protects? I am aware that NFPA 14 paragraph 7.5.1 states "*Where two or more standpipes are installed in the same building or section of building, they shall be interconnected*." But for this specific case there would be no standpipes.
