### PERMIT SUBMITTAL

Specifications for total flooding and local application clean agent fire extinguishing systems shall be prepared under the supervision of a person fully experienced and qualified in the design of such systems and with the advice of the authority having jurisdiction. The specifications shall include all pertinent items necessary for the proper design of the system. Working plans and calculations shall be submitted for approval to the authority having jurisdiction before system installation or remodeling begins. Deviation from these documents shall require permission of the authority having jurisdiction. Working plans shall be drawn to an indicated scale and shall show the following items that pertain to the design of the system:

- 1. Point of compass and symbol legend.
- 2. Location and construction of protected enclosure walls and partitions.
- 3. Location of fire walls.
- 4. Enclosure cross section, full height or schematic diagram, including location and construction of building floor/ceiling assemblies above and below, raised access floor and suspended ceiling.
- 5. Agent being used.
- 6. Design extinguishing or inerting concentration.
- 7. Description of occupancies and hazards being protected, designation whether or not the enclosure is normally occupied.
