(a) Pumps shall be of approved centrifugal type, capable of delivering at least 200 GPM, and shall be capable of supplying the calculated flow and pressure demand of the sprinkler system.

(b) Pumps shall be maintained under approved automatic control with closed circuit supervisory attachment. The supervisory attachments shall be directly connected to an office where maintenance personnel are in attendance twenty-four hours a day; or, in lieu thereof, the supervisory attachment may be directly connected to the central station of an approved operating fire alarm company. The supervisory alarm services shall be arranged so as to provide positive indication at an approved central office or sprinkler alarm panel board that the pump has operated or that the source of electrical supply has failed.

(c) Such pumps shall also comply with the applicable provisions of this Referenced Standard and the New York City Building Code pertaining to Fire Pumps, except that only one water supply and no enclosure shall be required.

(d) Power to such pumps shall be supplied from the street side of the building service switch. Secondary power shall be provided where required by other provisions of this code.

(e) If a secondary power supply is provided to drive the pump and such power supply is automatic switching, the 5 PSI requirement in section 15.2.2.4 and the requirements of paragraph (d), for power to be supplied from the street side of the building service switch, may be waived.

15.2.3.1.1 Each tank shall be kept at a maximum of ⅔ full of water and a minimum of ⅓ full of air maintained under a minimum pressure of 75 psig. The water-to-air ratio shall be so proportioned and the tank so located that a minimum pressure of 15 psig will be available on the highest line of sprinklers below the main roof when all the water has been discharged from the tank.

15.2.3.1.2 The tank supports shall be designed on the basis of a full tank. The tanks shall be supplied with water through a fixed pipe, independent of the sprinkler piping and at least 2 inch in size. The water supply shall be capable of supplying the tank at a rate of at least 65 gpm without decreasing the pressure in the tank. The tank shall have a fixed water level plate on the end of the tank opposite the gage glass, or equivalent devices, to indicate the level of the water in the tank.

The Reserve shall be sized for the greater demand, in accordance with NFPA 14, section 7.10.1.3. For purposes of this section, limited shall be defined as less than 30 percent of the floor area on the given floor. Buildings whose occupancies are more than 85 percent light hazard may have a light hazard water supply, provided the ordinary hazard areas are designed for ordinary hazard requirements with respect to sprinkler spacing and pipe sizing.
Add Section 15.2.4.2 Combined standpipe and sprinkler systems may be used in Occupancies A, B, E, F, I, M, R and S. If an automatic fire pump is used as the primary supply, the requirements of 15.2.2.1 shall apply.

In these cases, hydrostatic tests in accordance with Reference Standard NFPA 13-2002, as modified for New York City, are necessary. Dry systems should also be tested by placing the system under 40 pounds (2.8 bar) air pressure. Any leak that results in a drop in system pressure greater than 2 psi (0.14 bar) in 24 hours should be corrected. Check for leaks using soapy water brushed on each joint or coupling. Leaks will be shown by the presence of bubbles. This test should be made prior to concealing of piping.

(2) Automatic fire pumps connected to an approved water source in accordance with NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection and the following:

(a) Any required automatic fire pump shall draw from two independent street water mains in different streets, except that: (1) any automatic fire pump serving a building classified in occupancy group R-2 that is fully protected by a system of automatic sprinklers may draw from a single water main; and (2) an automatic fire pump may draw from a single water main if augmented by a suction tank or tanks, and if the valves at the meter and pump are provided with tamper switches that are wired to an approved central station of an operating fire alarm company. Where two services are installed, one service from the street water main shall be run directly to the pump, and the other service may be used for domestic water supply. The connection from water to the mains to the pumps shall be at least six inch pipe size and shall be flushed before connection is made to the system. Connections shall be in accordance with the provisions of the New York City Plumbing Code and applicable referenced standards.

Such relief valve shall be set to relieve below the shutoff head of the pump, but above the pressure required to maintain the operating pressure at the highest hose valve. The discharge from the relief valve may be piped back into the suction side of the pump on the pump side of the suction valve provided a visual sight glass is installed in the discharge of the relief valve. Automatic fire pumps may be provided with a time delay switch to insure a minimum running time for the pump.

(h) The check valves in the pump discharge line shall be either swing type or spring loaded.
