39 Section 903 Automatic Sprinkler Systems As per the DOB s summary of the NYC s New Construction Code: This section is organized by Occupancy Group and establishes the conditions that require installation of an automatic sprinkler system, based upon occupant load, fire area and building area. For nearly all Occupancy Groups, this section is more restrictive than the current code and will require sprinkler systems in spaces and buildings where such systems are currently not required.

40 Section 903 Automatic Sprinkler Systems This section also the provides the requirements for locations that are exempt from the provisions of this section and are protected by alternative fire extinguishing systems. The current code does not provide an equivalent provision, although alternative systems have been approved for use in New York City in the past. This section codifes the practice. This section requires all residential occupancies to be equipped with an automatic sprinkler system, with exceptions for one- and two-family homes and townhouses. The current code requires sprinkler systems only in residential occupancies J-1 and J-2 and does not extend the requirement to all residential occupancies.

41 Section 903 Automatic Sprinkler Systems This section provides specific locations for quick-response automatic sprinklers in spaces and buildings that require automatic sprinkler system protection. The equivalent does not appear in the current code. This section requires high rise buildings to provide secondary on-site water supply equal to the hydraulically calculated sprinkler demand. The equivalent does not appear in the current code. All other provisions of this section are equivalent to the current code.

87 Section Smokeproof Enclosures Smokeproof enclosures in highrise buildings consisting of an enclosed interior exit stairways, each provided with one of the following: An open exterior balcony A naturally ventilated vestibule (2 hr rated) A mechanically ventilated vestibule (2 hr rated) Pressurization within the stairway

88 Section 912 Post-fire Smoke Purge Systems Required in: High-rise buildings subject to Section 403 Buildings with any story exceeding 50,000 sq. ft. Buildings with spaces exceeding 100 feet from natural ventilation openings. High piled stock or rack storage in accordance with the NYC Fire Code.

89 Section 912 Post-fire Smoke Purge Systems As per the DOB s summary of the NYC s New Construction Code: This section provides the requirements for the design and installation of post-fire smoke purge systems intended for the timely restoration of operations and overhaul activities once a fire has been extinguished. This section is equivalent to the current code, with the exception that R-2 occupancies are not required to provide a smoke purge system if the building is provided with smokeproof enclosures.

90 Appendix Q Modified National Standards for Automatic Sprinkler, Standpipe, and Fire Alarm Systems Q101 Scope. This appendix provides the modifications to the nationally recognized standards NFPA 13, NFPA 13D, NFPA 13R, NFPA 14 and NFPA 72, governing the installation and maintenance requirements of automatic sprinkler, standpipe and hose systems, and fire alarm systems.

91 Appendix Q Modified National Standards for Automatic Sprinkler, Standpipe, and Fire Alarm Systems Q102. Installation of Sprinkler Systems. Provides the NYC modifications of the nationally recognized standard NFPA 13 Standard for the Installation of Sprinkler Systems, 2002 edition. The current code references ANSI/NFiPA No , Standard for the Installation of Sprinkler Systems. Though the majority of the modifications are equivalent in scope, the referenced standard in this section is up-to-date and more relevant to current technologies and practices

92 Appendix Q Modified National Standards for Automatic Sprinkler, Standpipe, and Fire Alarm Systems Q102. Installation of Sprinkler Systems. The requirements for sprinklers in commercial cooking applications are deleted in their entirety from NFPA 13 since the proposed code does not permit the use of water sprinkler systems in such applications. The current code permits such system in the modifications of ANSI/NFiPA No. 13.

93 Appendix Q Modified National Standards for Automatic Sprinkler, Standpipe, and Fire Alarm Systems Q102. Installation of Sprinkler Systems. The current code modifications to ANSI/NFiPA No. 13 require approval by the Department of specified devices and systems. The modifications to NFPA 13 by the proposed code do not require Department approval and wholly accept devices and systems listed for their use by nationally recognized testing entities.

94 Appendix Q Modified National Standards for Automatic Sprinkler, Standpipe, and Fire Alarm Systems Q103. Installation of Sprinkler Systems in One- and Two- Family Dwellings and Manufactured Homes Provides the NYC modifications of the nationally recognized standard NFPA 13D, Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, 2002 edition. The current code references ANSI/NFiPA No , Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes. Though the majority of the modifications are equivalent in scope, the referenced standard in this section is up-to-date and more relevant to current technologies and practices.

95 Appendix Q Modified National Standards for Automatic Sprinkler, Standpipe, and Fire Alarm Systems Q104. Installation of Sprinkler Systems in Residential Occupancies up to and Including Six Stories in Height Provides the NYC modifications of the nationally recognized standard NFPA 13R, Standard for the Installation of Sprinkler Systems in Residential Occupancies up to and Including Four Stories in Height, 2002 edition. The current code references ANSI/NFiPA No. 13R 1994, Standard for the Installation of Sprinkler Systems in Residential Occupancies up to and Including Four Stories in Height. Though the majority of the modifications are equivalent in scope, the referenced standard in this section is up-to-date and more relevant to current technologies and practices.

96 Appendix Q Modified National Standards for Automatic Sprinkler, Standpipe, and Fire Alarm Systems Q105. Installation of Standpipe and Hose Systems Provides the NYC modifications of the nationally recognized standard NFPA 14, Standard for the Installation of Standpipe and Hose Systems, 2003 edition. The current code does not modify a nationally recognized standard, and instead provides requirements in Subchapter 17 of the Building Code and the Reference Standards. Furthermore, systems and devices that are listed in accordance with this standard are permitted as-of-right and do not require Department approval as per the current code.

97 Appendix Q Modified National Standards for Automatic Sprinkler, Standpipe, and Fire Alarm Systems Q105. Installation of Standpipe and Hose Systems The modifications of NFPA 14 are equivalent to the current code in most applications. However, the modifications provided by this section differ from the current code for those regulations that apply to very tall buildings. -Manual Fire Pumps no longer required -Redundant automatic and gravity-fed water supplies required -Design requirements exceed the requirements of the current codes through the requirement for much larger tank sizes for onsite storage of water for fire-fighting purposes, through the requirement for a dedicated high pressure siamese riser, and through a zoned system that improves fire fighting capabilities.

98 Appendix Q Modified National Standards for Automatic Sprinkler, Standpipe, and Fire Alarm Systems Q106. Installation and Maintenance of Fire Alarm Systems Provides the NYC modifications of the nationally recognized standard NFPA 72, National Fire Alarm Code, 2002 edition. The current code references ANSI/NFiPA No , National Fire Alarm Code. Though the majority of the modifications are equivalent in scope, the referenced standard in this section is up-to-date and more relevant to current technologies and practices. Furthermore, systems and devices that are listed in accordance with this standard are permitted as-of-right and do not require Department approval as per the current code.

99 International Fire Code Intent. The purpose of this code is to establish the minimum requirements consistent with nationally recognized good practice for providing a reasonable level of life safety and property protection from the hazards of fire, explosion, or dangerous conditions in new and existing buildings, structures and premises and to provide safety to fire fighters and emergency responders during emergency operations. Proposed New York City Fire Code Intent. The purpose of this code is to establish reasonable minimum requirements and standards for life safety and property protection, to accomplish the purposes set forth in Section
