WET PIPE SPRINKLER SYSTEM, FIRE PROTECTION

PART 1

GENERAL

All Fire Protection System design, modification, and installations shall be in accordance with UFC 3-600-01: Fire Protection Engineering for Facilities. The UFC 3-600-01 required Fire Protection Designer shall provide a performance designed system or a fully designed system as applicable. This section is primarily intended for performance designed systems, i.e., systems where the size, layout, and support of branch lines and cross mains, and the layout of sprinkler heads will be designed by the Fire Protection Designer.
The Fire Protection Designer shall provide the following information in the contract documents for performance designed systems. (1) Show the layout and size of all piping and equipment from the point of connection to the water supply, to the sprinkler cross mains. The contract drawings must include a detailed sprinkler riser diagram. Water velocity in the piping should not exceed 6 m/s (20 ft/s). (2) Show location and size of service mains, interior feed mains, control valves, sprinkler risers, drain lines, sectional valves, and inspector's test valves and switches on the drawings.
(3) Specify water flow data including hydrant flow results, including the location where the hydrant flow test was conducted, the location and size of existing mains and new water supply lines that will serve the sprinkler system (including all supervisory valves), and the location and size of all risers.
(4) Highlight or clearly indicate the area(s) to be protected by sprinklers on the drawings.
(5) Specify water flow requirements including the design density, design area, the hose stream demand (including location of the hose stream demand), the duration of supply, and sprinkler spacing and area of coverage in this section.
(6) Show the location of the backflow preventer (including provisions for a drain and access for maintenance) where the potable water supply system is at risk of contamination by the sprinkler system on the drawings. (7) Show all provisions necessary for forward flow testing of the backflow preventer at system demand, as required by NFPA 13 on the drawings. Indicate location of all components and required items, including test ports, for pressure measurements both upstream and downstream of the backflow preventer, a drain to the building exterior, and appropriate, permanent means of disposing of the large quantity of
