I was going to say that at well BUT, since they are free standing and can be moved, if relocated, the sprinkler spacing pattern could be made ineffective or non-compliant. How could you space sprinklers based on a potentially changing "wall" layout?
If there is a distinct possibility that these panels can be rearranged, and in order to be able to provide a sprinkler layout that would be fixed for the open space I would inform the tenant that the height of the partitions needs to be lowered to allow a clearance of at least 18"-24" below the ceiling. Panels at 7'-6" would help with sprinkler issues and would probably be of benefit to the HVAC distribution as well. Otherwise install 4ft flexheads (or equal) so that they can be moved around to accommodate any changes in position of the panels. Craig L.

So, I would say sprinkler both sides being careful to remain at least 6'-0" apart and maintaining 130 sq. ft. per head. Just my $.02 Thomas Watt Could someone please help me with this question? How would pendant sprinklers be located around a free standing partition in a ordinary hazard occupancy? The NFPA only seems to address this for light hazard.I have 8"-10" partitions in an area with a 9'-6" ceiling in a "mall store". Any input would be helpful. Scott Enides S.R.I.
