LAFD Chief’s Regulation No.4 - 2014 Edition
GENERAL TEST PROCEDURES
Sprinkler Systems, Automatic: Wet, Dry, Pre-action, Deluge & Foam (continued) (15) Foam-Water Sprinkler Systems: Testing of foam water sprinkler systems shall be conducted to ensure that the foam-water system(s) operates as designed, both automatically and manually. Testing procedures shall simulate anticipated emergency events so the response of the foam-water system can be evaluated in accordance with NFPA 16, 16A, Title 19/NFPA 25 California edition and recommended test procedures as per manufacturer’s specifications. NOTE: This regulation shall not apply to junior sprinkler systems of less than 21 sprinkler heads and sprinkler systems designed and installed in accordance with NFPA-13D, (standard for the installation of sprinkler systems in one and two family dwellings and manufactured homes). See F-340R Fire Protection Equipment Performance Report for additional procedures (where provided). N. Standpipe Systems: Determine that all equipment is in proper operating condition and well maintained in accordance with applicable portions of NFPA-14 and Title 19/NFPA 25 California Edition (1)
Class I Dry and Class III (Class III Combination of Class I Wet and Class II Wet): (a) Fire Department Connections: Ensure that appropriate inlet connections are provided in operable condition. Verify that approved signs are in place and have the correct information If signs are missing or incorrect, the Certified Tester shall place the information in section V of the F-340R Fire Protection Equipment Performance Report for Fire Department inspection/follow-up. (b) Flush Fire Department Connection and piping using an approved method to remove obstructions and/or debris from the inlet connection and piping as stated in Section 4-M-(a). (c) Air Test: Air test dry systems to a maximum of 25 psi for 30 minutes to determine if the system leaks. This is to avoid water damage to the building if piping has been damaged or disconnected.
NOTE: An air test is not required on outside piping. (d) Hydrostatic Test: Class I Dry: Fill the system completely with water and note the static pressure (head) on a test gauge installed on the lowest inlet connection. Hydrostatically test the system at a pressure 50 PSI greater than the head pressure but in no case less than 200 PSI for 3 minutes. Class III Combination: Use procedures found in Section 4-M (2) of this manual
