Based on the plan F2.0, the automatic fire sprinkler deluge system depicted in the stage area supplies a total of
24 fire sprinklers. This is determined by counting the sprinkler heads indicated on the plan in the stage area, which are connected to the deluge system. The deluge system is designed to activate all sprinklers simultaneously in a high-hazard area, such as a stage, to provide rapid fire suppression across a large area.
NFPA 13, Standard for the Installation of Sprinkler Systems, provides the requirements for the design and layout of such systems.
