NFPA° 720 Standard for the Installation of Carbon Monoxide (CO) Detection and Warning Equipment 2015 Edition Wiering Eguipent was prepared by the Technical Committe on Carbon Monoxide Detec This edition of NFPA 720 Stenderd for the Instaflation of Carbon Monoxide (CO) Drtection end 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 Association Technical August 14 2014 with an effective date of Sptember 3 2014 and supeees ll previous Meeting held June 912 2014 in Las Vegas NV. It was issued by the Standards Council on editions. This edlition of NFPA 720 was approved as an American National Standard on September 3 2014. Origin and Development of NFPA 720 With the increased concerm over carbon monoxide (CO) hazards in residential applicar- tions the National Fire Protection Asociation was petitioned to develop a document cover- ing the installation of CO detectors and related equipment. In late 1993 the Technical Com- mittee on Household Fire Warning Equipment was tasked to develop a document covering the installtion and use of CO detectors. This dcument was originally prepared by the Tech- nical Committee on Household Fire Warning Equipment but was returned to mittee at the 1995 Annual Meeting. The NFPA Standards Coumcil later aproved the formation of the Technical Committe on Carbon Monoxide and Fuel Gas Detectors to further develop this document. a as o po a q d o sosu pepa paau uo go a Technical Cowmitte Docmets Those revisions included the adition of three administrative chapters at the beginning of the document: “Administration “Referenced Publications ° and Definitions. Two technical chapters followed the administrative chapters: “General Provisions" from Chapter 1 (in part) of the 1998 ediion and “Household Carbon Monoxide Warning Equipment* from Chapter 2 of the 1998 edition. Editorial revisions also included breaking out paragraphs with multiple requirements into individually umbered paragraphs minimizing the use of exceptions and using consistent headings for sections and subsections. consistent and ser friendly The 200S edion alo contned technical resions icling Changes alsowere mad in some sections to provide language and teminology that was more the remendation that printed instructions for carbon monoxide alarms and detectors include minimum and remended distances from fuel-burning appliances. uaxq poatq as a uq equipment requirements by localjurisdictions for the installtion of this equpment became more mon and the need for an installation standard written in enforceable language became eident. The 2005 edition of NFPA 720 reflected that need it was changed from a remende practice to a standard. In addition tems such as fmly iig it and ose Aol were replaced where appropriate with the term dlling it to prode language con sistent with standard terminology used in NFPA codes and standards. The 2009 edition was a plete renrite of the standard and addressed installations of Carbon monoxide detection systems in mercial types of applications as well as the instal- lation of carbon monoxide waming equipment in household applications. The 2009 edition ws largely extracted from the 2007 edition of NFPA 72 Ntional Fise Alrm Cods and was NFPA72were showwith theextractreferene inbrackesat theend f the paragraph.In organized in a fashion similar to that of NFPA 72. Paragraphs that were extracted from some cases modiications were made to the extracte txt to useteminology appropriate fr this standard such as the term cerbon monoxide instead of firz.

Some of the technical changes in the 2009 edition included the introduction of requirements for the placement of carbon monoxide detectors in mercial applications. Those requirements were based on the Fire Protection Re search Foundati report Dept of α Tehical Bsis for Crbn Mnxide Der Stig Reh Pj. In addition requirements for the siting power supply and interconnection of carbon monoxide alarms were upclated. The previous edition of NFPA 720 was largely extracted from the 2007 edition of NFPA 72 Extensive changes were made in the organization and contentof the 2010 edition of NFPA 72. As aresult the extract material from NFPA 72was updated in the 2012 edition of NFPA 720 to pronide consisteney.

In similar manner where terms were deleted empty brackets were shown such as where the word smoke was removed from the term smoke alerm. Several noteorthy technical changes were also included in the 2012 edition of NFPA 720. These includled an expanded definition of the term *carbon monoxide alarm*; a revision of the secondary power requirement for systems monitored by a supervising station; a revision of the record of pletion form and the inspection testing and mintenance fom; an addition of a pronsion to permit performancehased designs for the location of system CO detector; ew provisns for lowfreqeny aibe signaling for sleeping areas; removal of requirements for sesit ity testing of system CO detectors; revisions to address the replacement of bination smoke/CO alarms; new provisions to addres signaling to the deaf and hard of hearing in applications of CO alarms and household CO detection systems; new provisions for CO alarms that use wirelessignals to interconnect alarms within a household; and updated provisions for the transmission of signals from a household CO detection system to a supervising station. have been updated in this edition to maintain consistency with the 2013 edition of NFPA 72. The same convention for As with the tro previous elitions the 2015 edition of NFPA 720 is largely extracted from AFFA 72. Numerous extracts identifying the extracts s well as editorial changes to the extacts has been used as in the previous to eitions. Technical changes have also been included in the 2015 edition of NFPA 720. These include the following: revision of requirements for personnel qualifications in Chapter 4 so they are more specific to CO systems; revision of the requirements for the audible CO alarm signal in Chapters 5 and 9 to allow the use of more than one tone; revision of the inspection and testing tables in Chapter 8 so they are consistent with the format used in AFPA 72; revision of the ments in Chapter 9 for distinctive alarm signals to make it clear that CO fire and other alarm sigals must each use a requirements in Chapter 9 for secondary power supply standby capacity from 8 to 24 hours; revision of the require different audible signal; and the addition of new Annex C Guidelines for Emergency Responders. 2015 Edifion
