I am looking at a building that has 12' ceilings (per floor). In one area there is a vertical opening to the second floor that is protected with closely spaced sprinklers and draft stops. Is it still acceptable to use the quick response area reduction or does the opening to the second floor count as a ceiling in excess of 20'?
If it is acceptable to use the quick response reduction, can you apply the reduction to the length of closely spaced sprinkler heads that must be calc'd?
