coupling shall be equipped with an approved
___________________________________________
✔✔fire department connections -✔✔Remote _________________________________
shall be located adjacent to a street or an access route to permit the fire department
apparatus accessibility, or at a location approved by the AHJ.
✔✔1.) The sign shall have a raised or engraved letters at least 1 in. (25 mm) in height
on a plate or fitting.
2.) The sign shall indicate the type of system for which the connection is intended. -
✔✔Each Remote fire department connection shall be designated by a sign as follows:
✔✔150 psi (10.3 bar) -✔✔Where the system demand pressure exceeds
______________________, a sign located at the fire department connection shall
indicated the required inlet pressure.
✔✔indicating valves, roadway box, municipal water supply -✔✔All valves controlling
connections to water supplies and to supply pipes to water-based fire protection
systems shall be listed _________________________ except for when installed in a
_______________________________ when acceptable to the AHJ and a new
connection to a _________________________
✔✔ The Standard shall cover the minimum requirements for the installation of private
service mains and their appurtenances, which include the following -✔✔-Automatic
Sprinkler Systems
-Open Sprinkler Systems
-Water Spray Fixed Systems
-Foam Systems
-Private Hydrants
, -Monitor Nozzles or Standpipe Systems with reference to water supplies
-Hose Houses
✔✔The standard shall apply to combined service mains intended to carry water for fire
service and other uses -✔✔
✔✔This standard shall NOT apply to the following situations -✔✔-Mains under the
control of a water utility
-Mains providing fire protection and/or domestic water that are privately owned but are
operated as a water utility
✔✔The standard shall NOT apply to underground fire mains serving sprinkler systems
designed and installed in accordance with NFPA 13R that are less than 4 in in nomimal
diameter -✔✔
✔✔The standard shall not apply to underground mains serving sprinkler systems
designed and installed in accordance with NFPA 13D -✔✔
✔✔The Purpose of this standard shall be to provide a reasonable degree of protection
for life and property from fire through installation requirements for private service main
systems based on sound engineering principles, test data, and field experience. -✔✔
✔✔The provisions of this standard reflect a consensus for what is necessary to provide
an acceptable degree of protection from the hazards addressed in this standard at the
time the standard was issued. -✔✔
✔✔Residual Pressure -✔✔The pressure that exists in the distribution system, measured
at the residual hydrant at the time the flow readings are taken at the flow hydrants.
✔✔Static Pressure -✔✔The pressure that exists at a given point under normal
distribution system conditions measured at the residual hydrant with no hydrants
flowing.
✔✔Check Valve -✔✔A valve that allows flow in one direction but prevents flow in the
opposite direction.
✔✔Indicating Valve -✔✔A valve that has components that show if the valve is open or
closed. Examples are outside screw and yoke (OS&Y) gate valves and underground
gate valves with indicator posts.
✔✔Dry-Barrel Hydrant -✔✔Fire hydrant that has its operating valve located at the base
or foot of the hydrant rather than in the barrel of the hydrant. When operating properly,
there is no water in the barrel of the hydrant when it is not in use. These hydrants are
used in areas where freezing may occur.
