If they are combination sprinkler/standpipe risers, NFPA 14 would require interconnection.

An addition is being added to an existing building. Existing building is fully sprinklered. The total area of the combined existing and new structure exceeds 52,000 sf and the existing system riser is in the far corner away from the addition. So the decision was made to bring in a new underground supply to serve the new addition. Thus the new addition will have its own independent system riser and fire department connection. Does 2002 NFPA 13 section 8.16.l2.4.3 (or any other section) require the two FDCs (one existing, one new) be tied together? The commentary hints at this, but I've never thought that was the intent. I thought the intent was that multiple systems SERVED BY THE SAME UNDERGROUND LEAD-IN be served by the same FDC. Section 8.16.2.4.5 seams to support this. Opinions?
