According to *11.2.3.4.1 *you only need to calculate 3 sprinklers in service chute when supplied by a separate riser...I am just digging for full understanding here...
If you start at the 1st floor and feed a chute through multiple floors fed from a single vertical pipe off the Dry System, does that meet the intent of a separate riser if said pipe does not have a separate control valve? If the answer is no, do you calculate it as a corridor (single row) up to 7 heads? If the vertical pipe feed a single sprinkler on each floor but they are not in a service chute and each floor is sealed from the other, can you calculate the largest room and only flow one sprinkler on the highest floor?
