4. Where the underside of roof sheathing exceeds 14' and does not exceed 24' to the <br />finished floor, a sprinkler design of 0.45 gallons per minute calculated over the <br />hydraulically most remote 3,000 square feet, with a maximum coverage of 100 square <br />feet per sprinkler is required. A 500 gallon per minute allowance for hose streams shall <br />also be provided. <br />5. Where the underside of roof sheathing is 24' feet or more to the finished floor, a <br />sprinkler design of .60 gallons per minute calculated over the hydraulically most remote <br />3,000 square feet, with a maximum sprinkler spacing of ten by ten feet (10'X10') or <br />eight by twelve feet (8'X12'). A 500 gallon per minute allowance for hose streams shall <br />also be provided. <br />Where specific hazards known at the time of original construction require higher <br />densities than required per above items 2, 3, 4, or 5 the higher densities shall be <br />provided based on nationally recognized standards. <br />20.24.120 CFC Section 903.3.1 Badded -NFPA 13 sprinkler systems. <br />CFC Section 903.3.1 B is added. <br />903.3.1 B <br />A minimum design area of 3,000 square feet shall be required for all <br />industrial/commercial sprinkler systems (NFPA 13). Where subsequent occupancy <br />requires a sprinkler system of greater design density or area of application capability, it <br />shall be the responsibility of the owner and/or occupant to retrofit the sprinkler system <br />to the required code or standard in order to obtain clearance for the new occupancy or <br />use. <br />20.24.130 CFC Section 903.3.1 Cadded -Installation of Fire Sprinkler Systems. <br />CFC Section 903.3.1 C is added. <br />Section 903.3.1 C <br />Fire sprinkler protection shall be provided in all combustible and non-combustible <br />concealed spaces. <br />20.24.140 CFC Section 903.3.1.2 added -NFPA 13R sprinkler systems. <br />CFC Section 903.3.1.2 is added. <br />Section 903.3.1.2 <br />Requirements for 4 to 15 dwelling units up to 12,000 square feet. <br />1. The hydraulically most remote six (6) sprinklers shall be calculated for each area. <br />When a common sprinkler and domestic water supply is provided, the fire sprinkler <br />demand shall include the simultaneous domestic flow of 5 gallons per minute per unit. <br />The domestic flow shall be added at the base of the riser. <br />ss <br />
