GENERAL REQUIREMENTS
[Preaction] [Deluge] sprinkler system(s) shall be provided in [areas
indicated on the drawings] [_____]. The sprinkler system shall provide
fire sprinkler protection for the entire area. Except as modified herein,
the system shall meet the requirements of NFPA 13 and NFPA 72. The
sprinkler system shall be a single interlocked system that requires the
actuation of an alarm initiating device to open the water control (deluge)
valve. The Contractor shall design any portion of the sprinkler system
that are not indicated on the drawings including locating sprinklers,
piping, and equipment, and size piping and equipment when this information
is not indicated on the drawings or is not specified herein. Pipe sizes
which are not indicated on the drawings shall be determined by hydraulic
calculations.
1.2.1
Hydraulic Design
**************************************************************************
NOTE: Applications requiring multiple
densities/design areas must be referred to and shown
on the drawings.
Systems covering 140 square meters (1500 square
feet) or greater will be hydraulically designed.
Only systems less than 140 square meters (1500
square feet) may be designed using the pipe schedule
method of NFPA 13. This section must be edited if
the system is to be designed using the pipe schedule
method.
**************************************************************************
The system shall be hydraulically designed to discharge a minimum density
of [_____] L/min per square meter gpm per square foot over the
hydraulically most demanding [280] [_____] square meters [3,000] [_____]
square feet of floor area. The minimum pipe size for branch lines in
gridded systems shall be 32 mm (1-1/4 inch). Hydraulic calculations shall
be in accordance with the Area/Density Method of NFPA 13. Water velocity
in the piping shall not exceed 6 m/s 20 ft/s.
1.2.1.1
Hose Demand
An allowance for exterior hose streams of [_____] L/min gpm shall be added
