AUTOMATIC SPRINKLER SYSTEM AND STANDPIPE SYSTEMS Fire Suppression Systems Fire suppression systems shall not provide connections for non-fire items. All components of fire suppression systems shall be listed for their use. Secondary Supply In addition to the main water supply, a secondary on-site supply of water equal to the total standpipe demand at duration of 30 minutes shall be provided. The standpipe design shall be 500 gpm at the most remote standpipe, plus 250 gallons for every additional standpipe. Design shall be per the requirements of NFPA 14. This secondary supply shall be automatically available if the principal supply fails. The water supply used to comply with this requirement shall be designed and installed based on the requirements of NFPA 22 and its appendix. A fill device shall be installed to automatically maintain the required water supply. The tank shall automatically refill whenever the volume of the tank is less than 105% of the required capacity. A. Open type reservoirs, pools, fountains, or wells shall not be used as the on-site water supply. B. Only approved corrosion resistant type tanks shall be permitted. C. The on-site water supply shall be provided with trouble indicators and shall be interconnected to the Life Safety Control Panel. The following alarms shall be audibly and visually indicated at the Life Safety Control Panel as a separate zone: 1. Water temperature below 40 deg F 2. Return of water temperature to 40 deg F 3. Water level 3” below normal 4. Water level above normal 5. Return of water level to normal 6. Pressure in tank 10 psi below normal Page 3 of 30 updated last 06/12/2017 West Sacramento Fire Department Fire Prevention Bureau HIGHRISE BUILDING STANDARD 7. Pressure in tank 10 psi above normal D. The authority having jurisdiction shall approve locations of auxiliary water tanks and controls. E.

The second required FDC shall be provided at a remote location from the principal Fire Department Connection. Both FDC and their piping shall be interconnected so that in the event one becomes disabled or unavailable, the other can be engaged, and/or used simultaneously.

Landings shall be sized to allow the standpipe outlet does not interfere with the required stairway width as required by the 2016 CBC. Standpipe systems shall be an automatic wet system Class 1. NFPA 14 section 5.2. Standpipe outlet pressure limitations shall meet NFPA 14 section 7.2 A pressure gauge with a minimum scale from zero (0) to three-hundred (300) psi shall be installed at the connection from the riser to the outlet to monitor the actual pressure being delivered at the location. A mean for testing each standpipe outlet shall be provided. Temporary Fire Pump and Standpipes During construction, when standpipes exceed 20 floors (or 275 feet) a temporary or permanent pump shall be installed and connected at that level and be available for Fire Department use.
