N.Y.C. Admin. Code § 760.130: Section 760.130

Section 760.130 – Revise Section 760.130 to read as follows:

(A) NPLFA Wiring Methods and Materials. Installation shall be in accordance with 760.46, and conductors shall be solid or stranded copper.

Exception: The ampacity adjustment factors given in 310.15(B)(3)(a) shall not apply.

(B) PLFA Wiring Methods and Materials. Power-limited fire alarm conductors and cables described in 760.179 shall be installed as detailed in 760.130(B)(1), (B)(2), or (B)(3) of this section and 300.7. Devices shall be installed in accordance with 110.3(B), 300.11(A) and 300.15 with all wiring supported from the building structure independently.

(1) In Raceways, Exposed on Ceilings or Sidewalls, or Fished in Concealed Spaces. In raceways or exposed above 8 ft (2.4 m) on the surface of ceiling and sidewalls, or fished in concealed spaces, cable splices or terminations shall be made in listed fittings, boxes, enclosures, fire alarm devices, or utilization equipment. Where installed exposed, cables shall be supported at a maximum of 5 ft (1.5 m) spacing and installed in such a way that maximum protection against physical damage is afforded by building construction. Where located within 8 ft (2.4 m) of the floor, cables shall be installed in raceway as per Article 342, 344, 358 or 386. Where flexibility is required after installation, Flexible Metallic Conduit (FMC) or Liquidtight Flexible Metallic Conduit (LFMC) shall be permitted up to 36 inches (915 mm) at the last termination.

(2) Passing Through a Floor or Wall. Cables shall be installed in metal raceways where passing through a floor or wall to a height of 8 ft (2.4 m) above the floor, unless adequate protection can be afforded by building construction such as detailed in 760.130(B)(1) or unless an equivalent solid guard is provided.

Informational Note: Protection by building construction includes, but is not limited to, raised floors, shafts, telephone and communications equipment rooms and closets, and rooms used exclusively for fire alarm equipment.

(3) In Hoistways. Cables shall be installed in rigid metal conduit, intermediate metal conduit, or electrical metallic tubing, where installed in hoistways.

Exception: As provided for in 620.21 for elevators and similar equipment.

(4) Terminations and Splices. Terminations and splices shall be made in listed fittings, boxes, enclosures, fire alarm devices, or utilization equipment. Splices shall be limited to locations where the conditions of installation require the use of splices. Splices and terminations in riser cables are prohibited except where made in fire alarm equipment terminal cabinets. Mechanical connections shall be listed in accordance with UL 486A - 486C or if soldered, conductors shall first be joined so as to be mechanically and electrically secure prior to soldering. Temperature rating of completed splices shall be equal to or exceed the temperature rating of the highest rated conductor.

(5) Physical Protection. Where a Smoke Control System is provided, all wiring, regardless of voltage, shall be installed in raceways.

Informational Note: For additional information on Smoke Control System wiring requirements, refer to Chapter 9 of the New York City Building Code.
