FIRE PROTECTION AND SAFETY
4.7.1
FIRE PROTECTION SYSTEMS
A. Automatic sprinkler and gaseous extinguishing system piping layouts
shall not be designed; i.e., a piping plan will generally not be provided to show new
work. Such a plan may be necessary to indicate existing piping sizes and locations or
to show pipe routing where interference problems exist. In instances where
architectural and interior design features are critical (e.g. lobbies, clubs, BEQ/BOQ
rooms), it may necessary to show sprinkler head or piping locations. A schematic riser
diagram is required and points of connection must be identified.
B. Describe fire detection and alarm systems including location of detectors,
manual stations, audible devices, control panel, etc. Number of conductors shall not be
indicated unless required to ensure proper interface with existing systems or for
unusual or complex systems.
C. Indicate location of water supply main entrance to building and detail of
sprinkler valves. Also indicate location and details of gaseous extinguishing system
equipment and supplies; show piping to the extent required by space limitations,
where potential interference problems may occur, etc.
D. Refer to the latest edition of MLHDBK-1008 "Fire Protection for Facilities
Engineering, Design, and Construction" for specific applications and requirements for
various types of fire protection systems. Such systems must meet applicable NFPA
standards.
E.
Provide the following information about sprinkler systems:
(1) Authority for installation of sprinkler systems,
(2) Hazard classification of occupancy and whether system will be
hydraulically calculated or follow the pipe schedule method.
(3) For hydraulically designed systems, state density and area of
application as well as water supply available at point of connection (static pressure and
residual pressure at design flow). This data must be based upon flow tests at or near
the point of connection and must appear in the Basis of Design.
