§ 13.04.330. NFPA 13.

A subsection, designated "8001.1 NFPA 13, Standard for the Installation of Fire Sprinklers," is amended to read as follows:

8001.1 NFPA 13, Standard for the Installation of Fire Sprinklers. NFPA 13-2016 is available from the National Fire Protection Association, 1 Batterymarch Park, P.O. Box 9101, Quincy, Massachusetts, 02269-9101. The National Fire Protection Association Standard for the Installation of Fire Sprinklers is hereby adopted by reference with the following modifications:

Section 8.2.6 of NFPA 13 is deleted in its entirety.

Section 8.15.8.1.1.1 of NFPA 13 is added to read as follows:

8.15.8.1.1.1 Sprinkler protection shall not be required in separate rooms that contain solely a toilet fixture, that contain no counters, shelving, closet doors, or other fixtures, and that have a maximum area of 55 ft (5.1 m ). Such rooms shall be surrounded by walls and doors that completely enclose the room.

Section 8.15.28 of NFPA 13 is amended to read as follows:

8.15.28 Openings in Rated Assemblies. Where sprinkler protection is serving as the alternative to opening protection in rated assemblies, such sprinklers shall be listed for use, and installed in accordance with their listing. These sprinklers shall be a separate sprinkler system, and shall be controlled, monitored, and supplied independently of the overhead system(s).

Section 8.16.4.1.4 of NFPA 13 is added as follows:

8.16.4.1.4 Listed heat-tracing systems shall be permitted in accordance with 8.16.4.1.4.1 and 8.16.4.1.4.2.

Section 8.16.4.1.4.1 of NFPA 13 is added as follows:

8.16.4.1.4.1 Where used to protect branch lines, the heat-tracing system shall be specifically listed for use on branch lines.

Section 8.16.4.1.4.2 of NFPA 13 is added as follows:

8.16.4.1.4.2 Electric supervision of the heat-tracing system shall provide positive confirmation that the circuit is energized.

Section 10.1.2 of NFPA 13 is amended to read as follows:

10.1.2* All piping used in private fire service mains shall be rated for the maximum system working pressure to which the piping is exposed but shall not be rated at less than 150 psi (10 bar). When the underground piping can be supplied or pressurized by a fire pump or a Fire Department Connection (FDC), the underground piping shall be designed to withstand a working pressure of not less than 200 psi (Class 305), or 50 psi greater than the FDC design pressure, whichever is greater.

Section 10.2.2 of NFPA 13 is amended to read as follows:

10.2.2 All fittings used in private fire service mains shall be rated for the maximum system working pressure to which the fittings are exposed, but shall not be rated at less than 150 psi (10 bar). When the underground piping can be supplied or pressurized by a fire pump or a Fire Department Connection (FDC), the underground piping shall be designed to withstand a working pressure of not less than 200 psi (Class 305), or 50 psi greater than the FDC design pressure, whichever is greater.

Section 11.3.1.1 of NFPA 13 is amended to read as follows:

11.3.1.1 The design area shall be in accordance with either 11.2.3.2 or 11.2.3.3.

Section 23.1.3.1 of NFPA 13 is added to read as follows:

23.1.3.1 General Notes shall be added to the plans to provide clarity of design. The plans shall contain the following general note narratives:

(1) Describe the scope of work that is covered by permit. Indicate where sprinklers are being provided and for what purpose. For permits where the scope of work is only over a portion of a facility, the area of work shall be marked by a boundary line that is labeled "Scope of Work," and the narrative shall address this situation.

(2) Provide a general description of building use and associated occupancy classification per NFPA 13 for all building areas

(3) Indicate whether area is designed for storage. If the sprinkler system is being designed to accommodate storage, indicate the commodity storage height, storage configuration (rack, solid-pile, etc.), aisle width between racks as applicable, commodity classification per NFPA 13, and whether commodity is encapsulated.

(4) Indicate the manufacturer, schedule, and type of branch line piping

(5) Indicate the manufacturer, schedule, and type of main piping

(6) Indicate the manufacturer, schedule, and type of fittings and couplings

(7) Indicate the manufacturer, schedule, and type of underground piping

(8) Indicate the manufacturer, model number and type of water meter assembly

(9) Indicate the type of freeze protection provided (i.e. building heated to 40°F at all times, dry system, etc.)

(10) Indicate the maximum system pressure for each riser/system, and indicate the minimum pressure required for the hydrostatic test of each riser/system.

(11) Indicate the maximum sprinkler deflector distance below the roof deck

(12) Indicate the type of construction, whether combustible or non-combustible

(13) Indicate whether there are any combustible concealed spaces. Indicate how combustible concealed spaces are protected.

(14) Indicate whether construction is classified as unobstructed or obstructed construction

(15) Indicate the ceiling flatness and material. Indicate whether the ceiling is horizontal and flat, or it has a slope, has soffits, or other variations in ceiling height. For all instances of soffits and other variations of ceiling height, refer to details for each instance shown on the plan. Indicate whether ceiling materials consist of thin combustible membranes, such as stretch plastic or fabric. Any installation under a thin combustible membrane shall be accompanied by an approved engineering analysis.

(16) Indicate whether central station is required.

(17) Indicate the location of the sprinkler head box, and indicate that the room where the box is located is conditioned to 100 degrees F or less.

Section 24.2.1.11 of NFPA 13 is amended to read as follows:

24.2.1.11 When pressure testing in CPVC piping and fittings, the sprinkler system shall be slowly filled with water and the air bled from the highest and farthest sprinkler heads before pressure testing is applied. Air or compressed gas must never be used for pressure testing of CPVC piping and fittings.
