30、tallation of Carbon Monoxide (CO) Detection andWarning Equipment, was prepared by the Technical Committee on Carbon Monoxide Detec-tion (SIG-CAR), released by the Correlating Committee on Signaling Systems for the Protec-tion of Life and Property (SIG-AAC), and acted on by NFPA at its June Associati
31、on TechnicalMeeting held June 912, 2014, in Las Vegas, NV. It was issued by the Standards Council onAugust 14, 2014, with an effective date of September 3, 2014, and supersedes all previouseditions.This edition of NFPA 720 was approved as an American National Standard on September 3,2014.Origin and
32、Development of NFPA 720With the increased concern over carbon monoxide (CO) hazards in residential applica-tions, the National Fire Protection Association was petitioned to develop a document cover-ing the installation of CO detectors and related equipment. In late 1993, the Technical Com-mittee on
33、Household Fire Warning Equipment was tasked to develop a document coveringthe installation and use of CO detectors. This document was originally prepared by the Tech-nical Committee on Household Fire Warning Equipment but was returned to committee atthe 1995 Annual Meeting. The NFPA Standards Counci
34、l later approved the formation of theTechnical Committee on Carbon Monoxide and Fuel Gas Detectors to further develop thisdocument.The 2003 edition reflected editorial revisions to comply with the Manual of Style for NFPATechnical Committee Documents. Those revisions included the addition of three a
35、dministrativechapters at the beginning of the document: “Administration,” “Referenced Publications,”and “Definitions.” Two technical chapters followed the administrative chapters: “GeneralProvisions” from Chapter 1 (in part) of the 1998 edition and “Household Carbon MonoxideWarning Equipment” from C
36、hapter 2 of the 1998 edition. Editorial revisions also includedbreaking out paragraphs with multiple requirements into individually numbered paragraphs,minimizing the use of exceptions, and using consistent headings for sections and subsections.Changes also were made in some sections to provide lang
37、uage and terminology that was moreconsistent and user friendly. The 2003 edition also contained technical revisions, includingthe recommendation that printed instructions for carbon monoxide alarms and detectorsinclude minimum and recommended distances from fuel-burning appliances.As communities beg
38、an to recognize the life safety benefit of carbon monoxide warningequipment, requirements by local jurisdictions for the installation of this equipment becamemore common, and the need for an installation standard written in enforceable languagebecame evident. The 2005 edition of NFPA 720 reflected t
39、hat need it was changed from arecommended practice to a standard. In addition, terms such as family living unit and house-hold were replaced, where appropriate, with the term dwelling unit, to provide language con-sistent with standard terminology used in NFPA codes and standards.The 2009 edition wa
40、s a complete rewrite of the standard and addressed installations ofcarbon monoxide detection systems in commercial types of applications as well as the instal-lation of carbon monoxide warning equipment in household applications. The 2009 editionwas largely extracted from the 2007 edition of NFPA 72
41、, National Fire Alarm Code, and wasorganized in a fashion similar to that of NFPA 72. Paragraphs that were extracted fromNFPA72 were shown with the extract reference in bracketsattheendoftheparagraph. Insome cases, modifications were made to the extracted text to use terminology appropriate forthis
42、standard, such as the term carbon monoxide instead of fire. In those instances, brackets7201NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.encased the modified words. In a similar manner, where terms we
43、re deleted, empty brackets were shown, such as wherethe word smoke was removed from the term smoke alarm.Some of the technical changes in the 2009 edition included the introduction of requirements for the placement ofcarbon monoxide detectors in commercial applications. Those requirements were based
44、 on the Fire Protection Re-search Foundation report Development of a Technical Basis for Carbon Monoxide Detector Siting Research Project. In addition,requirements for the siting, power supply, and interconnection of carbon monoxide alarms were updated.The previous edition of NFPA 720 was largely ex
45、tracted from the 2007 edition of NFPA 72. Extensive changes weremade in the organization and content of the 2010 edition of NFPA72. As a result, the extract material from NFPA72 wasupdated in the 2012 edition of NFPA 720 to provide consistency. As in the 2009 edition, paragraphs that were extractedf
46、rom NFPA 72 were shown with the extract reference in brackets at the end of the paragraph. In some cases,modifications were made to the extracted text to use terminology appropriate for this standard, such as the term carbonmonoxide instead of fire. In those instances, brackets encased the modifying
47、 words. In similar manner, where terms weredeleted, empty brackets were shown, such as where the word smoke was removed from the term smoke alarm.Several noteworthy technical changes were also included in the 2012 edition of NFPA 720. These included anexpanded definition of the term “carbon monoxide
48、 alarm”; a revision of the secondary power requirement for systemsmonitored by a supervising station; a revision of the record of completion form and the inspection, testing, andmaintenance form; an addition of a provision to permit performance-based designs for the location of system COdetectors; n
49、ew provisions for low-frequency audible signaling for sleeping areas; removal of requirements for sensitiv-ity testing of system CO detectors; revisions to address the replacement of combination smoke/CO alarms; newprovisions to address signaling to the deaf and hard of hearing in applications of CO alarms and household COdetection systems; new provisions for CO alarms that use wireless signals to interconnect alarms within a household;and updated provisions for the transmission of signals from a household CO detection system to a supervising station.As with the two previ
