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)
Each new fire pump shall be given an acceptance test for one hour and shall deliver its rated capacity at the required speed and net pressure. Pumps rated at less than 1,500 gpm shall deliver 150 percent of the rated capacity at 65 percent of its rated pressure. The test shall not cause the bearings in the pump or on its motor, engine or turbine to become excessively heated. On electric driven fire pumps, there shall be no increase in the temperature of the electric wiring, electric windings of the motor and electric current carrying devices on the control panel other than as noted on the ratings of the various equipment.
Automatic operation of the fire pump shall be verified by a pressure drop in the system. The test shall include manual starting and stopping of the pump.
All electric wiring to the fire pump motor including the controller, emergency power supply, and pressure maintenance pump shall be completed prior to the acceptance test. The pressure at the intake side of the pump shall not be less than five pounds per square inch under any flow rate.
An acceptance test shall be performed on any pump in which the impeller is replaced or repaired.
All such tests shall be performed by an independent contractor licensed under the Illinois Fire Sprinkler Contractor Licensing Act in the presence of the fire commissioner.
(Prior code § 91-96; Amend Coun. J. 10-30-96, p. 31261, § 1; Amend Coun. J. 5-18-16, p. 24131, § 129)
An annual test shall be made of each fire pump during which time water shall be discharged from the highest hose outlet of each riser. At least one riser shall be flowed for five minutes. Each fire pump shall deliver its rated capacity at its rated pressure through a test manifold or wall hydrant for a period of at least ten minutes. All such tests shall be performed by an independent contractor licensed under the Illinois Fire Sprinkler Contractor Licensing Act in the presence of the fire commissioner. A fee of $31.50 for each 50 gallon pumping capacity per minute shall be charged for each fire pump tested, with a minimum fee of $315.00 for each fire pump tested. The aforestated fees shall not be assessed with respect to any building used solely as a school operated by the Chicago Board of Education.
(Prior code § 91-97; Amend Coun. J. 7-13-94, p. 53399; Amend Coun. J. 10-30-96, p. 31261, § 1; Amend Coun, J, 11-16-11, p. 13798, Art. VIII, § 3; Amend Coun. J. 5-18-16, p. 24131, § 130; Amend Coun. J. 11-14-18, p. 90376, Art. V, § 6)
It shall be the duty of the fire commissioner to cause an inspection to be made of all standpipe systems at least once every year by an independent contractor licensed under the Illinois Fire Sprinkler Contractor Licensing Act. Such inspections shall be schedule with, and may be overseen by or in the presence of, the fire commissioner. If such inspection discloses any violations of, or variation from, the requirements of this Code pertaining to standpipes or standpipe systems, or any defective conditions which would handicap the operation of the standpipe system, notice shall be sent to the owner or agent in control of the building containing such standpipe system to remove or correct such defective conditions within such time as shall be set forth in said notice. It shall be the duty of the building owner to pay the comptroller an inspection fee of $50.00 for each standpipe, other than a manual dry standpipe, inspected in connection with such annual inspection.
