8、 standards, recom-mended practices, and guides (“NFPA Standards”), made available for use subject to Important Notices and Legal Disclaimers, which appear at the end of this handbook and can also be viewed at www.nfpa.org/disclaimers.Notice Concerning Code Interpretations: This 2016 edition of the N

9、ational Fire Alarm and Signaling Code Handbook Handbook is based on the 2016 edition of NFPA 72. All NFPA codes, standards, recommended practices, and guides (“NFPA Standards”) are developed in accordance with the published procedures of the NFPA by technical committees comprised of volunteers drawn

10、 from a broad array of relevant interests. The handbook contains the complete text of NFPA72 and any applicable Formal Interpretations issued by the NFPA at the time of publication.

13、FPA codes, standards, recommended practices, and guides (“NFPA Standards”), may be amended from time to time through the issuance of Tentative Interim Amendments or corrected by Errata. An official NFPA Standard at any point in time consists of the current edition of the document together with any T

19、cate this edition to Lee Richardson, editor of the Fourth, Fifth, Sixth, and Seventh editions of the handbook. Lee was senior electrical engineer at NFPA and a longtime NFPA employee. He retired in 2015 after many years as staff liai-son of NFPA 72, National Fire Alarm and Signaling Code, and NFPA 7

20、20, Standard for the Installation of Carbon Monoxide (CO) Detection and Warning Equipment. Lee was tenacious, detailed, and dedicated to fire alarm safety. He was also strongly committed to the codes and standards consensus development process by which the National Fire Alarm and Signaling Code is d

21、eveloped. Over the years, Lee worked with many Technical Committees and Task Groups and served on several industry committees and panels. He also served as staff liaison for many other NFPA documents, including NFPA 85, NFPA 86, NFPA 86C, and NFPA 86D.Lee will be greatly missed at NFPA, and we wish

22、him well in his retirement.BK-NFPA-72HB16-150223-FM.indd 5 9/14/2015 8:16:38 PMBK-NFPA-72HB16-150223-FM.indd 6 9/14/2015 8:16:38 PMviiContentsPreface xiAcknowledgments xiii About the Contributors xvAbout the Editors xixPART ONENFPA 72, National Fire Alarm and Signaling Code, 2016 Edition, with Comme

The first signaling standard, NFPA 71-D, General Rules for the Installation of Wiring and Apparatus for A

48、utomatic Fire Alarms, Hatch Closers, Sprinkler Alarms, and Other Automatic Alarm Systems and Their Auxiliaries, was written in 1899. That document was only fifteen pages in length, including the committee report. We are certain the original framers of that document would be astonished to see what th

49、eir work looks like today.Fire alarm signaling has come a long way since NFPA published that first signaling standard over one hundred years ago. Many technologies related to fire alarm systems have evolved, while others have changed little since the middle part of the nineteenth century. For example, conventional fixed-temperature heat detectors and McCulloh loops have not changed significantly since they were invented in the late 1800s. Many technologies emerged in just the past thirty or forty years. More recent technologies,
