facilities. For sprinklered facilities that are not high-piled storage, this
distance may be required only to one full side of the facility containing the
fire department access into the building such as the main entrance), including

where neither a PIV nor a WPIV is feasible, such as at inner city locations
where sidewalks would be obstructed. Valves in pits, Post Indicator Valves, and
other valves (other than key valves in roadway boxes) controlling the water
supply to Fire Hydrants/Sprinkler System shall each be electrically supervised
with a Tamper Switch in accordance with NFPA 13 (2002), Section 8.15.1.1.2.1(1)

a pumper fire hydrant. If such connections are not mounted on the building they
serve, they shall be located at least 100-ft (30.5 m) from the building they
serve and not more than 50 ft (15.4 m) and not less than 25-ft (7.6m) from a

500-ft of all points of the exterior of the building. A minimum 3-ft clearance
around each fire hydrant shall be maintained, and shall include bollards where
subject to vehicular impact. Supplies to fire hydrants used for pumper
connections to the FDC (i.e. pumper fire hydrant) shall be located upstream of
