SECTION 2.
SPRINKLER SYSTEMS
DESIGN OF SPRINKLER SYSTEMS:
2.1
2.1.1 Navy and Air Force Projects:  Design criteria differs between Navy
and Air Force projects.  Navy requirements for occupancy classification,
design density, remote area and hose stream allowances are specified in
MIL-HDBK-1008A (dated 31 March 1988).  Air Force requirements are contained in
AFR 88-15.
Sprinkler Coverage:  Sprinkler protection for all areas of the
2.1.2
building shall be included under the sprinkler specification section.
Sprinkler protection for freezers, coolers and covered loading docks shall be
specifically called for in the contract plans and specifications.  Do not
specify sprinklers coverage under separate specifications sections for special
areas, such as trash chutes, paint spray booths, elevators, etc.
HYDRAULIC ANALYSIS:  The A-E shall conduct water flow tests at the
2.2
proposed site and include pertinent test data in the 35% design package. The
A-E is also responsible for determining if the water supply is adequate to
meet sprinkler and hose stream demands.  For hydraulic calculations, deduct
the hose stream requirement at the point of connection to the existing
distribution system or the closest fire hydrant, whichever is closer to the
sprinkler riser.  If these demands cannot be met, the A-E shall provide proper
solutions to the problem of an insufficient water supply, i.e., fire pump(s),
and/or water storage tank(s).  It is imperative that possible problems and
solutions be identified as early possible.  See Page VI-l of Attachment C of
Appendix N for required format of water supply data. Provide reference points
on drawings to show where water supply data is given.  All systems over 3,000
square feet shall be hydraulically calculated.
SPRINKLER HEADS
2.3
Temperature Rating:  Use intermediate temperature rated (212oF)
2.3.1
o
sprinklers wherever NFPA 13 (1991 edition) requires ordinary (165 F)
o
temperature rating.  Use high temperature rated (286 F) sprinklers at
ceiling/roof level of warehouse occupancies for storage heights under 25 feet
high.
2.3.2
On-off Intermittent Sprinkler Heads:
Do not use or specify
"on-off" intermittent sprinkler heads.
Use tamper proof sprinklers in all detention and
2.3.3
BRIG Facilities:
correctional facilities.
Piers and Wharfs:  Sprinkler heads below a combustible pier or
2.3.4
wharf shall be pendant sprinkler heads installed in the upright position.  All
sprinkler heads shall be of the corrosion resistant type.
Child Development Center:  Sprinkler heads in areas occupied by
2.3.5
o
children shall be quick-response with 165 F temperature rating.
