If your home's water capacity was 10 GPM, you could place 3 heads per zone.How many fire sprinkler heads do I need?
Minimum Distance Between Sprinklers: typically 6'-0". Distance from Ceiling: minimum 1", maximum 12" for unobstructed construction. The minimum 1" is typical; however, concealed, recessed, and flush sprinklers may be mounted less than 1" from the ceiling and shall be installed based on their listing.Who determines building occupancy?
