Semonious, Deputy Fire Chief/Fire Marshal Prevention and Technical Services Division (559) 621-4181 FAX (559) 498-4323 Fresno Fire Department 911 H Street Fresno, CA 93721-3082 β€œTo protect and put service above all else.” FIRE INDUSTRY BULLETIN 2020-002 SCOPE This industry bulletin covers all previously approved residential sprinkler standard plans and the adoption of the 2019 California Building Code, California Fire Code and California Residential Code that took effective January 1, 2020. PURPOSE The purpose of this bulletin is to provide a procedure for C-16 contractors to continue to utilize previously approved standard fire sprinkler plans prepared under the 2016 edition of NFPA 13D. BACKGROUND The 2019 California Codes referenced above adopt, with amendments, the 2016 edition of NFPA 13D as the referenced standard for the installation of residential sprinklers in one and two-family dwellings. Due to the number of approved plans on file, a procedure has been formulated to allow continued use of the previously approved plans for installation in the upcoming code cycle. The following are State and/or Fresno Fire Department amendments to NFPA 13D: 1. A minimum of 5 gpm domestic demand must be added to fire sprinkler demand. 2. The domestic water lateral in a standalone system must have a shut-off valve so that fire sprinklers remain in service during a domestic water distribution system repair. 3. Attached garages must have fire sprinklers installed in all storage rooms and closets (2019 FMC 10-50903.2.8.1.2). 4. All attic, overhead and above ceiling storage rooms must have fire sprinklers installed (2019 FMC 10-50903.2.8.1.1). 5. All attic, crawl spaces and normally unoccupied concealed spaces that contain fuel-fired appliances must have fire sprinklers installed above the equipment. Fire Industry Bulletin 2020-002 Page 2 Fire sprinklers shall not be required in the remainder of the space (2019 California Residential Code, Section R313.3.1.2). Requirements/interpretations remaining in effect: 1. Passive purge connections for each toilet as described in a previous section. No other plumbing fixtures may be supplied from the standalone piping system. 2. The primary control valve (house valve) must be an indicating valve (i.e., a quarter turn ball valve). 3. No control valve is allowed in a standalone system supply lateral. 4. A ½ inch minimum drain valve is required after the required NSF 61 Annex β€œG” check valve in a standalone system. Provide a fire sprinkler orifice if the system is provided with a water flow switch. 5. For multipurpose systems, house drinking water fixtures including the water heater supply, must be on a separate pipe run from fire sprinkler supply unless ultralow lead fire sprinkler heads are installed throughout the system. 6. All pipe used for fire sprinkler installation shall be approved for domestic plumbing. Local building and safety requirements prohibit the use of steel pipe in the domestic water systems, including galvanized pipe. INFORMATION 1. Contractors that would like to continue utilization of the previously approved plans must complete three copies of the FFD Residential Fire Sprinkler Plan Code Equivalency Request form for each standard plan on file with the FFD. 2. FFD staff will provide a new fire permit template number for the 2019 Code cycle and place an approval stamp on each copy of the form. 3. A fee will be assessed to process each form submitted based on the Master Fee Schedule in effect at the time of approval (the fee in effect as of January 24, 2020, is $154). NOTE This notice is effective January 27, 2020.
