Latest version.
  • Chapter 35 Referenced Standards is adopted in its entirety with the following amendments:

    NFPA 13, 2016 Edition, Standard for the Installation of Sprinkler Systems is hereby amended as follows:

    SECTION 6.7.3 is hereby amended to read as follows:

    6.7.3 Fire department connections (FDC) shall be of an approved type. The location shall be approved and be no more than 150 feet from a public hydrant. The FDC may be located within 150 feet of a private fire hydrant when approved by the Fire Code Official. The size of piping and the number of 2½" inlets shall be approved by the Fire Code Official. If acceptable to the water authority, it may be installed on the backflow assembly. Fire department inlet connections shall be painted OSHA safety red or as approved. When the fire sprinkler density design requires more than 500 gpm (including inside hose stream demand), or a standpipe system is included, four 2½" inlets shall be provided.

    SECTION 8.3.3.1 is hereby amended to read as follows:

    8.3.3.1 When fire sprinkler systems are installed in shell buildings of undetermined use (Spec Buildings) other than warehouses (S occupancies), fire sprinklers of the quick-response type shall be used. Use is considered undetermined if a specific tenant/occupant is not identified at the time the fire sprinkler plan is submitted. Sprinklers in light hazard occupancies shall be one of the following:

    1.

    Quick-response type as defined in 3.6.4.8.

    2.

    Residential sprinklers in accordance with the requirements of 8.4.5.

    3.

    Quick response CMSA sprinklers.

    4.

    ESFR sprinklers.

    5.

    Standard-response sprinklers used for modifications or additions to existing light hazard systems equipped with standard-response sprinklers.

    6.

    Standard-response sprinklers used where individual standard-response sprinklers are replaced in existing light hazard systems.

    SECTION 11.1.1.1 is hereby added as follows:

    11.1.1.1 When fire sprinkler systems are required in buildings of undetermined use other than warehouses, they shall be designed and installed to have a fire sprinkler density of not less than that required for an Ordinary Hazard Group 2 use, with no reduction(s) in density or design area. Warehouse fire sprinkler systems shall be designed to Figure 16.2.1.3.2 (d) curve "G". Use is considered undetermined if a specific tenant/occupant is not identified at the time the sprinkler plan is submitted. Where a subsequent use or occupancy requires a system with greater capability, it shall be the responsibility of the occupant to upgrade the system to the required density for the new use or occupancy.

    SECTION 11.2.3.1.1.1 is hereby added as follows:

    11.2.3.1.1.1 The available water supply for fire sprinkler system design shall be determined by one of the following methods, as approved by the Fire Code Official:

    1.

    Subtract the project site elevation from the low water level for the appropriate pressure zone and multiply the result by 0.433;

    2.

    Use a maximum of 40 psi, if available;

    3.

    Utilize the OCFA water-flow test form/directions to document a flow test conducted by the local water agency or an approved third party licensed in the State of California.

    NFPA 13D 2016 Edition, Standard for the Installation of Sprinkler Systems in One-and Two-Family Dwellings and Manufactured Homes is hereby amended as follows:

    (a)

    For buildings less than 40 ft (12 m) in height, a post indicator valve shall be permitted to be installed closer than 40 ft (12 m) but at least as far from the building as the height of the wall facing the post indicator valve.

    2.

    A wall post indicator valve.

    3.

    An indicating valve in a pit, installed in accordance with Section 6.4.

    4.
