§ 905-01 Standpipe System Pressure Reducing Devices.
RCNY § 905-01
(a)Scope. This section sets forth requirements for standpipe system pressure reducing devices.
(b)Definitions. The following terms shall, for purposes of this section and used elsewhere in the rules, have the meanings shown herein: Pressure reducing devices. Devices, including valves, installed in standpipe systems at or near hose outlet connections that act to limit both the static and dynamic water pressures downstream of the standpipe outlet valve. Pressure restrictors. Removable fittings or "SECO Type" valves that restrict flowing water pressures by reducing the available cross-sectional area of flow.
(c)General Provisions.
(1)Certificate of approval. Pressure reducing devices installed in a standpipe system shall be of an approved type and for which a certificate of approval has been issued.
(d)Pressure Reducing Device Requirements.
(2)Adjustments and reporting. Upon initial installation of a pressure reducing device, and at least once every three (3) years thereafter, a master fire suppression contractor shall file an affidavit with the Department on behalf of the building owner attesting to the following: (A) The building address and owner's name. (B) The floor location of all standpipe system pressure reducing devices and the inlet pressure (static and operating) of each device. (C) The setting of each device and the corresponding discharge flow rate (gpm), discharge pressure (psig), and the maximum outlet static pressure (psig). (D) The name, address, and master fire suppression contractor license number of the person submitting the affidavit.
(3)Flow testing. Upon order of the Commissioner, but at least once every three (3) years, standpipe systems with pressure reducing devices installed shall be flow tested with a minimum actual flowing discharge of 250 gpm. These tests shall be conducted by a master fire suppression contractor who shall provide the Department five (5) business days notice of the date and time of the test. The Department may witness these tests at its discretion.
