§ 8309-01 Fire Protection Systems in Pre-Existing Facilities.
RCNY § 8309-01
(a)Scope. This section consolidates the Fire Prevention Code and former Fire Department rules in effect on June 30, 2008 that are applicable to the design and installation of fire protection systems in pre-existing facilities.
(b)Definitions. [Reserved.] (c) General Provisions. Pre-existing facilities with fire protection systems the design and installation of which would not be allowed or approved under the Fire Code, but which, pursuant to FC 102.3 and 3 RCNY § 102-01, may be continued with respect to such fire protection systems under the applicable laws, rules and regulations in effect prior to the Fire Code, shall continue to comply with the provisions of such laws, rules and regulations, including former Fire Department rules §§ 15-04, 17-01(d)(3)(iii), 17-07 and 17-08, as applicable, with respect to such fire protection systems, until such time as such facilities may be required to comply with the Fire Code and the rules with respect to the design and installation of such fire protection systems.
(d)Commercial Cooking Fire Extinguishing Systems.
(1)Former Fire Department Rule § 15-04 § 15-04 Extinguishing Systems for Hoods, Vent Pipes, Flues or Ducts* [*FOOTNOTE IN ORIGINAL: Section is applicable to systems installed on or after 12/14/62 but before 12/6/68. Systems or system changes made post 12/6/68 shall be in accordance with RS 13-3 (Building Code) and NYC Administrative Code §§ 27-4275 & 27-779.] (a) Plans. The installer or occupant shall submit three (3) sets of paper cloth drawings to the Bureau of Fire Prevention for approval before any work is commenced. These shall show the entire installation in plan and section, viz: all hoods; ducts; dampers; heat detector units; pipes; nozzles; fans; gas controls; automatic trip devices; manual operating controls; all other details for compliance with these regulations.
(c)Cleaning. The hood and exhaust ducts shall be thoroughly cleaned and be in good repair before the system is installed. They shall be so maintained at all times.
(f)Location of nozzles and heat detectors. The entire duct system and any deep frying units shall be provided with an adequate number of nozzles. One nozzle shall be installed at the inlet of each duct and one at the inlet side of the damper. Duct nozzles shall not exceed ten (10) feet on centers. Heat detecting units shall be located at all duct inlets. . . . . . . . . . .
(h)Carbon dioxide.
(2)Electrical requirements for the installation of thermostatic detection systems and the operation of safety devices when carbon dioxide systems are used as the extinguishing agent in hoods, vent pipes, flues or ducts to exhaust interior cooking spaces are: (i) Plans. The plans submitted for approval shall have marked thereon the location of the thermostatic detectors, the damper locations, all alarms, the electrical and mechanical operations of the safety devices as hereby required.
(ii)Equipment approval. All the electrical equipment shall be approved by the Board of Standards and Appeals or the Underwriters Laboratory for the installation for the class of detection, operation and alarm.
(iii)Wiring. The electrical equipment shall be operated on closed circuits, 120 volt systems. The wire shall be rubber covered RHW #14 AWG, installed in rigid iron or steel conduits.
(iv)Operation requirements. (A) The thermostatic device shall be either of a type that is manually reset or the control system shall be so arranged that some manual operation is required to restart the fan after the thermostat has operated. The thermostats shall operate on a 350°F. temperature. The thermostats shall be installed in a manner to enable the removal of the thermostat for repair or testing. (B) A light, normally on, installed within the hood installation room, to give indication that the source of current for the carbon dioxide system is out of service shall be required. (C) An alarm bell will be required when two or more 50 lb. carbon dioxide cylinders are required. The alarm shall sound upon the operation of the thermostatic device. (D) An emergency manual control, preferably in the form of a break glass station, to operate the system is required. (E) The fan shut down, gas valve closure, damper operations may be electrically or mechanically operated to operate the electric controls.
(i)Fine water spray. Where a fine water spray is used: All pipe sizes shall conform with and all valve sizes shall conform to the Building Code of the City of New York. The minimum static pressure at the highest nozzle shall not be less than thirty (30) p.s.i. One half (1/2) inch open, wide pattern nozzles shall be installed throughout. A water flow alarm may be installed if desired.
(j)Steam. Where steam is used: A continuous source of steam supply of not less than fifteen (15) p.s.i. shall be provided. The pipe sizes at the source of supply shall not be less than one and one-half (1 1/2) inches in diameter and not less than three quarter (3/4) inch for the last steam jet or outlet. Such outlet shall be a standard one-half (1/2) inch open sprinkler head. The pipe fittings and valve shall be steam standard. A control valve sealed open shall be located at the source of steam supply. A steam trap shall be installed on the steam line in such a location so as to remove all condensation up to the automatic control valve located at or near the ranges or ducts.
(k)Application. These rules shall apply to all new installations and to existing systems hereafter altered in any manner.
(e)Fire Alarm Systems.
(g)Wiring.
(3)When energy is supplied by a central station power system, the fire alarm cutout shall be the first connection, and as near as possible to the electric meter registering current consumed by the hall lighting system.
(4)The fusible cutout shall be contained in a sealed or locked metal cabinet painted Fire Department red, and stenciled, "Interior Fire Alarm." Not less than fifteen (15) ampere, enclosed type cartridge fuse will be accepted. Screw plug fuses are prohibited.
