  2. Title 29
  3. Chapter 2: New York City Fire Code

901.1 Scope.

This chapter shall govern the design, installation, operation and maintenance, including inspection and testing, of fire protection devices, equipment and systems, and other fire protection measures for the control and extinguishment of fire.

901.1.1 General.

Fire protection systems shall be designed, installed, operated and maintained in accordance with this chapter and the reference standards set forth in FC Table 901.6.1.

901.1.2 Emergency alarm systems.

Except as otherwise provided in the construction codes, this code or the rules, emergency alarm systems shall be designed, installed, operated and maintained in the same manner as fire alarm systems.

901.2 Design and installation documents.

The commissioner may require design and installation documents and calculations to be submitted for review for all fire protection systems. Design and installation documents required or regulated by this code or the rules shall be submitted for review and approval prior to installation, and shall certify that the design complies with the requirements of this code and the rules.

901.3 Permits.

Permits shall be required as set forth in FC 105.6.

901.4 Design and installation.

Fire protection systems shall be designed and installed in accordance with FC 901.4.1 through 901.4.6.

901.4.1 Required fire protection systems.

Fire protection systems shall be designed and installed in accordance with the construction codes, including the Building Code, and, as applicable, this code and the rules, and the applicable referenced standards listed in this code. Required systems shall be extended or altered as necessary to maintain and continue protection whenever the building or structure is altered. Alterations to fire protection systems shall be performed in compliance with the requirements of this code, the rules, and the construction codes, as applicable. Buildings and structures shall be provided with such fire hose, portable fire extinguishers and other means of preventing and extinguishing fires as the commissioner may direct.

901.4.1.1 Fire protection systems deemed required.

A fire protection system for which a design option, exception or reduction to the provisions of this code or the construction codes has been granted shall be deemed a required system.

901.4.2 Fire protection systems not required by code.

Any fire protection system or portion thereof not required by this code, the rules or the construction codes, including the Building Code, may be installed to provide partial or complete protection of a building or structure, provided such system meets the requirements of this code, the rules and the construction codes, including the Building Code, as applicable. Where the design and installation of such fire protection system is governed by this code or the rules, the commissioner may modify such requirements, consistent with the interests of fire safety, upon a determination that such modification will promote public safety by encouraging the installation of such systems.

901.4.3 Additional fire protection systems.

Where an existing or proposed storage, handling or use of a material or the conduct of an operation in a particular occupancy gives rise to special hazards in addition to the normal hazards of the occupancy, or where the commissioner determines that size, design and arrangement of the occupancy would unduly delay the ability of firefighting personnel to gain access to the hazard, the commissioner may require additional fire protection or other fire safety measures. Such measures may include the following: automatic fire detection systems, fire alarm systems, fire extinguishing systems, standpipe systems, or portable or fixed extinguishers. Where a certificate of occupancy limits the commissioner's authority to order the installation of such additional systems or the implementation of such additional measures, the commissioner may apply to the Board of Standards and Appeals for a modification of such certificate of occupancy, and such application shall be granted upon a showing that such additional systems or measures will reasonably mitigate the special hazard or delayed access.

901.4.4 Prohibition of deceptive equipment.

It shall be unlawful to install or maintain any device that has the physical appearance of fire protection equipment but that does not perform the fire protection function, in any building, structure or premises where it may be confused with actual fire protection equipment.

901.4.5 Certificate of approval.

The fire protection devices, equipment and systems listed in FC 112 shall be of a type for which a certificate of approval has been issued in accordance with this code, or which was approved by the Department of Buildings or the Board of Standards and Appeals prior to the effective date of this section, unless such approval by the Department of Buildings or the Board of Standards and Appeals is amended or repealed by the commissioner.

901.4.6 Connection to water supply.

Sprinkler systems, and other fire extinguishing and fire protection systems, connected to a potable water supply shall be protected against backflow in accordance with the construction codes and Department of Environmental Protection requirements.

901.5 Installation acceptance testing.

Fire detection and alarm systems, fire extinguishing systems, private fire hydrant systems, yard hydrant systems, standpipe systems, fire pump systems, private fire service mains and all other fire protection systems and appurtenances thereto shall be subject to acceptance tests as set forth in the installation standards specified in this code. Where required by the construction codes, including the Building Code, this code or the rules, such tests shall be conducted, at the owner's risk, by his or her representative before a representative of the department. When an installation does not pass an acceptance test required to be witnessed by the department, the necessary corrections shall be made and the installation retested, or, when authorized by the rules, certification of such corrections by a licensed or certified professional submitted to the department.

901.5.1 Occupancy.

It shall be unlawful to occupy any portion of a building or structure until all required fire detection systems, fire alarm systems, standpipe systems and fire extinguishing systems have been tested and approved, except as follows:

1. In a new building undergoing construction, a completed floor below the level of ongoing construction may be occupied upon installation, testing and approval of the required fire protection systems on all floors up to and including the occupied floor.

2. In an existing building undergoing alteration, a completed floor may be occupied upon installation, testing and approval of the required fire protection systems for such floor in accordance with Building Code and Department of Buildings requirements.

901.5.2 Correction of non-compliant conditions.

When the Department of Buildings authorizes occupancy of a building notwithstanding the existence of installation defects or other non-compliant conditions in the fire protection systems on the floors of the building in which occupancy has been authorized, any and all prior written inspection findings of such defects and other noncompliance shall, upon issuance of the occupancy authorization, constitute an enforceable violation of this code. Such violations shall be corrected within the time for correction set forth in the inspection finding, but in any event within 60 days of occupancy, unless additional time for compliance is granted by the department.

901.6 Maintenance.

Fire protection systems shall be maintained in good working order at all times. Any fire protection system that is not in good working order shall be repaired or replaced as necessary to restore such system to good working order, or, where authorized by the Building Code, removed from the premises.

901.6.1 Standards.

Fire protection systems shall be inspected, tested, serviced and otherwise maintained in accordance with this section, the rules and the referenced standards listed in FC Table 901.6.1. Where required by this section, such inspection, testing and maintenance shall additionally comply with the rules. Where applicable, the requirements of the reference standards listed in FC Table 901.6.1 shall be in addition to those requirements specified in the rules.
