Designated Number of Seats or Occupants
(4) (ii) Movable Seats
(c) Capabilities and components.
(1) Fire Alarm System: shall be closed circuit, "electrically supervised", individually coded and connected to an approved franchise/central office alarm company. A "supervised" system is one that is electrically monitored so that the occurrence of a single open or single ground fault condition of its wiring which prevents the required normal operation of the system or causes the failure of its primary (main) power supply source is indicated by a distinctive trouble signal.
(i) Manual fire alarm stations: shall be installed at each required natural path of egress from all levels from public assembly area.
(ii) Fire alarm gongs: shall be installed to provide adequate audibility throughout the Public Assembly area and all areas occupied in conjunction with the area at all levels including dressing rooms, rest rooms, coat rooms, etc. "Audibility" shall be loud and distinct under maximum sound system operation unless 1 RCNY §15-02(c)(2)(ii) is complied with.
(iii) Sprinkler waterflow device: shall be installed to indicate flow of water in the sprinkler system and shall be made part of the interior Fire Alarm by interconnecting the waterflow device to the interior Fire Alarm so that actuation of the waterflow device shall sound a distinctive coded alarm via the fire alarm gongs.
(2) General requirements.
(i) The components of the system shall require New York City M.E.A. approval.
(ii) A device may be installed to automatically turn off the sound system and psychedelic and special effects lighting when a manual fire alarm and/or sprinkler waterflow device is activated in all public assemblies that require an interior fire alarm and signal system.
(iii) A. SOURCES OF ELECTRICAL POWER Two sources of electrical power shall be provided as follows:
1. The primary source shall be generated electric power not exceeding 277/480 volts, supplied by utility company power, or isolated plant.
2. The secondary source shall be an emergency power system (as per Section 27-396 of the Building Code), an emergency generator and/or battery power.
3. One source of power shall be connected to the system at all times. The primary and secondary power sources shall be so arranged and controlled by automatic transfer switches and/or circuitry that when the primary source of power fails, the secondary source will be connected automatically to the fire alarm signal system. Intermediary devices between the system supply and the source of power, other than fused disconnect switches, transformers, fused cutouts and automatic transfer switches, are prohibited. Such disconnect switches, cutouts, transformers and automatic transfer switches shall supply only the fire alarm system and other systems covered by this reference standard. When the utility company requires the installation of metering current transformers, the system supply shall be connected on the load side of the current transformers. All installations shall comply with the applicable sections of the New York City Electrical Code. The primary source of power and the secondary source (if said secondary source is an emergency power system or generator) shall each be provided with a means of disconnect from the fire alarm system. For buildings supplied at 120/208 volts, each disconnect shall consist of a fused cutout panel, utilizing cartridge fuses, with provision for interrupting the unfused neutral and all ungrounded conductors. The neutral shall be provided with a removable solid copper bar. The incoming service neutral shall be bonded to the metallic housing of the cutout panel on the line side of the removable bar. The fused cutout panel housing shall consist of a locked metallic cabinet with hinged door, painted fire department red, and permanently identified as to the system served. For buildings served at 265/460 volts, the primary and secondary service disconnects shall be fused disconnect switches (in lieu of fused cutout panels) in locked, red painted, permanently identified enclosures. The service voltage shall be transformed to 120/208 volts and a fused cutout panel provided within 5 feet of the transformer on the 120/208 volt side. The incoming supply connections shall comply with the New York City Electrical Code, and the fused cutout panel shall comply with the requirements specified in this rule.
B. PRIMARY POWER SOURCE
