DEFINITIONS
1.2.1
Year 2000 compliant
Computer controlled facility components that accurately process date and
time data (including, but not limited to, calculating, comparing, and
sequencing) from, into, and between the twentieth and twenty-first
centuries, and the years 1999 and 2000 and leap year calculations.
1.3
SYSTEM DESCRIPTION
Design and provide [new and modify existing] automatic [deluge] [preaction]
fire extinguishing sprinkler systems for complete fire protection coverage
throughout [_____].
1.4
SPRINKLER SYSTEM DESIGN
**************************************************************************
NOTE: For areas smaller than 93 sq meters 1,000 sq
ft, use hydraulic calculations for deluge systems,
and use pipe schedules for preaction systems. For
areas larger than 93 sq meters 1,000 sq ft, use
hydraulic calculations complying with MIL-HDBK-1008
for deluge systems and for preaction systems. For
open areas larger than 929 sq meters 10,000 sq ft,
use hydraulic calculations. When hydraulic
calculations are not included, delete paragraphs
entitled "Water Distribution," "Density of
Application of Water," "Sprinkler Discharge Area,"
"Outside Hose Allowances," "Friction Losses," and
"Water Supply." Earthquake protection shall be
required for buildings in seismic zones 3 and 4, and
only essential and high risk buildings in seismic
zone 2.
**************************************************************************
Design automatic [deluge] [preaction] fire extinguishing sprinkler systems
in accordance with the required and advisory provisions of NFPA 13 [NFPA 15
], except as modified herein, by hydraulic calculations using the area
design method for uniform distribution of water over the design area. Each
system shall include materials, accessories, and equipment inside and
outside the building to provide each system complete and ready for use.
Design and provide each system to give full consideration to blind spaces,
piping, electrical equipment, ducts, and other construction and equipment
in accordance with detailed working drawings to be submitted for approval.
Locate sprinkler heads in a consistent pattern with ceiling grid, lights,
and air supply diffusers. Devices and equipment for fire protection
service shall be UL Fire Prot Dir listed or FM P7825 approved for use in
[deluge] [preaction] sprinkler systems. [Design systems for earthquake
protection.]
1.4.1
Location of Sprinkler Heads
Spacing of sprinklers and position and orientation of sprinklers in
relation to the ceiling, walls, and obstructions shall conform to NFPA 13
for [light] [ordinary] [_____]hazard occupancy [for the entire building]
[for [_____]areas]. Uniformly space sprinklers on the branch piping.
