Each standpipe system supplied by a fire pump shall be provided with a discharge test manifold or wall hydrant having one two and one-half inch individually valved hose connection for each 250 gpm of rated pump capacity. The discharge test manifold shall be located on an outside wall in allocation which will permit the safe discharge and drainage of water.
(Prior code § 91-88; Amend Coun. J. 10-30-96, p. 31261, § 1)
There shall be provided on the discharge side of each fire pump a pressure indicating gauge with indications from zero to double the working pressure of the system. A suitable compound pressure and vacuum indicating gauge shall also be provided on the suction of each fire pump.
(Prior code § 91-89; Amend Coun. J. 10-30-96, p. 31261, § 1)
All suction piping to the fire pump and all discharge piping, except standpipe risers, shall be painted red or identified as fire protection system piping at intervals of not less than 15 feet.
(Prior code § 91-90; Amend Coun. J. 10-30-96, p. 31261, § 1)
A dry pipe system shall be permitted only in a building, or a portion of a building, which is unheated.
The dry pipe system shall be isolated from the water supply, or from the wet portion of the system, if a combined wet and dry pipe system, by one or more dry pipe valves located at accessible points as near as practicable to tin dry system, adequately protected against mechanical injury and against freezing; piping shall be arranged so that each standpipe riser shall be provided with an independent dry pipe valve.
The valves shall automatically control the flow of water; they shall be constructed and installed so that under normal conditions, the portion of the piping in unheated spaces will remain dry. The operation of a hose valve will permit water to flow into the piping to supply water at the hose valve.
An instruction sheet giving full directions for the maintenance and operation of the dry pipe valve and the safe minimum and maximum air pressure to be maintained on the dry pipe valve shall be permanently posted in a conspicuous place near each dry pipe valve. A permanent sign shall be posted at each hose valve on a dry standpipe system reading “DRY STANDPIPE – AIR UNDER PRESSURE”.
(Prior code § 91-92; Amend Coun. J. 10-30-96, p. 31261, § 1)
A manual dry pipe system shall be permitted only as provided in Section 15-16-090(a)(5).
A manual dry pipe system shall comply with Sections 15-16-870 through 15-16-890, 15-16-920 through 15-16-940, 15-16-971, and 15-16-1020 through 15-16-1040, except that no hose connection shall be required above the roof.
A permanent sign shall be posted at each hose valve on a manual dry standpipe system and at the Fire Department connection reading “MANUAL DRY STANDPIPE.”
(Added Coun. J. 1-23-19, p. 94952, Art. II, § 3)
For all buildings requiring a standpipe system, there shall be installed during construction a standpipe system which will protect the building during construction. The standpipe shall be installed when the building height reaches 80 feet. When the height of the building reaches 300 feet, fire pumps shall be installed and in service. This may be part of the permanent installation or may be an independent temporary system. If a temporary system, it shall consist of a main to which shall be connected not less than one-half the number of risers required for the permanent system and supplied through not less than one-half the number of siamese connections located where easily accessible with a check valve at each siamese and risers carried up through the building provided with two and one-half inch valves with fire department thread located in each story. These connections shall be accessible and protected with non-corrodible lugged caps attached to the riser with a chain not less than eight inches long. Outlets shall be in accessible locations and installed so that hose can be attached without kinking or bending.
In buildings under construction the standpipe risers shall be extended so that the top hose connection is not more than two floors below the highest construction level. Risers shall be capped and kept closed at the top.
(Prior code § 91-93; Amend Coun. J. 10-30-96, p. 31261, § 1)
In all buildings or structures which are being reduced in height, wrecked or demolished and which are equipped with inside standpipe systems, the work of demolition shall proceed in such a manner that the systems will be maintained in an operative condition with the top of the risers not more than two stories below the top of the main structural supports of the building, or until the structural supports have leached a height of less than 40 feet above the street grade.
Siamese connections shall not be removed until the lowest section of the risers has been removed.
(Prior code § 91-94; Amend Coun. J. 10-30-96, p. 31261, § 1)
