  • Name of extinguishing agent to be used
  • Design fire extinguishing or inerting concentration
  • Description of occupancies and hazards being protected, designating whether or not the enclosure is normally occupied
  • Description of exposures surrounding the enclosure
  • Description of agent storage containers used including internal volume and storage pressure
  • Description of nozzle(s) used including size orifice port configuration, and equivalent orifice area
  • Description of pipe and fittings used including material specifications, grade, and pressure rating

  • Plan view of protected area showing the following:
    • Enclosure partitions
    • Agent distribution system including agent storage containers, piping, and nozzles
    • Type of pipe hangars and rigid pipe supports
    • Detection, alarm, and control system including all devices and schematic of wiring interconnection between them
    • End-of-line device locations
    • Location of controlled devices such as dampers and shutters
    • Location of instructional signage
  • Isometric view of agent distribution system showing the following:
    • Length and diameter of each pipe segment
    • Node reference numbers relating to the flow calculations
    • Fittings and orientation of tees and nozzles including size, orifice port configuration, flow rate, and equivalent orifice area;
  • Scale drawing showing the layout of the annunciator panel graphics
  • Details of each unique rigid pipe support configuration showing method of securement to the pipe and to the building structure
