63 of 326 11/21/2013 1:03 PM First Revision No. 80-NFPA 72-2013 [ ] 18.1.6 The requirements of Chapter 7 shall apply where referenced in Chapter 18. Submittal Date: Fri Jul 19 11:10:46 EDT 2013 : Chapter 18 does not reference Chapter 7. Public Input No. 412-NFPA 72-2013 [Section No. 18.1.6]
First Revision No. 81-NFPA 72-2013 [ Section No. 18.4.1.4 ] 18.4.1.4 Audible notification appliances for alert and evacuation signal tones shall meet the requirements of 18.4.3 (Public Mode Audible Requirements), 18.4.4 (Private Mode Audible Requirements), 18.4.5 (Sleeping Area Requirements), or 18.4.6 (Narrow Band Tone Signaling for Exceeding Masked Thresholds), as applicable. This requirement shall include audible tones that preceded or follow voice messages. 18.4.1.4.1* The designer of the audible notification system shall identify the rooms and spaces that will have audible notification and those where audible notification will not be provided. 18.4.1.4.2* Unless otherwise required by other sections of this Code, the coverage area for audible occupant notification shall be as required by other governing laws, codes, or standards. Where the other governing laws, codes, or standards require audible occupant notification for all or part of an area or space, coverage shall only be required in occupiable areas as defined in 3.3.178. 18.4.1.4.3 The sound pressure levels that must be produced by the audible appliances in the coverage areas to meet the requirements of this Code shall be documented by the system designer during the planning and design of the notification system. The greater of the expected average ambient sound pressure level or expected maximum sound pressure level having a duration of at least 60 seconds shall also be documented for the coverage area by the system designer to ensure compliance with 18.4.3, 18.4.4, 18.4.5, or 18.4.6 for the coverage area. 18.4.1.4.4 The design sound pressure levels to be produced by the notification appliances for the various coverage areas shall be documented for use during acceptance testing of the system. 18.4.1.4.5 Where required by the authority having jurisdiction, documentation of the design sound pressure levels for the various coverage areas shall be submitted for review and approval. Submittal Date: Fri Jul 19 11:15:41 EDT 2013 Committee Statement: Response Message: It has always been the intent to require a specific audible sound pressure level only for tones and not for voice. See existing 18.8.1.2 and Annex text for 18.4.1.5. The changes proposed and those accomplished by the TC make this clear in the code text. The submitter referred only to requirements for Public Mode. Existing 18.4.1.4 refers to all possible alert and evacuation tones including those other than Public Mode that might be used to preceded or follow a voice message. This places the requirement in the same location for all audible tones. The exception for the voice message itself remains unchanged and immediately follows this section. 64 of 326 11/21/2013 1:03 PM
First Revision No. 84-NFPA 72-2013 [ Section No. 18.5.5.7.2 ] 18.5.5.7.2* Table 18.5.5.7.2 shall apply to sleeping areas. Table 18.5.5.7.2 Effective Intensity Requirements for Sleeping Area Visible Notification Appliances in. Distance from Ceiling to Top of Lens mm Minimum Intensity (cd) 24 610 110 <24 <610 177 Supplemental Information File Name FR_84_Table.docx Description Submittal Date: Fri Jul 19 11:31:04 EDT 2013 Committee Statement: Response Message: The TC adds a minimum criterion to the third column heading. In regards to minimum, this correlates with the table headings in Table 18.5.5.4.1(a) and (b). 65 of 326 11/21/2013 1:03 PM

06 of 326 11/21/2013 1:03 PM First Revision No. 85-NFPA 72-2013 [ Section No. A.18.4.1.5 ] A.18.4.1.5 Because voice is composed of modulated tones, it is not valid to compare loudness measurements of tone signals with loudness measurements of voice signals. A voice signal that is subjectively judged to be equally as loud as a tone signal will actually produce a db reading below that of the tone signal. The modulated tones of a voice signal can have the same or greater peak amplitude as that of a tone signal. However, because they are modulated meters with fast or slow time, constants will show a lower db or dba reading. A voice signal must have sufficient audibility to result in intelligible communication. Intelligibility modeling/measurements (subject based and instrument based) include audibility as well as many other factors when determining whether a voice signal is adequate or not adequate. Where a voice signal includes an audible alert or evacuation tone, the tone portion of the signal should meet the audible signal requirements listed in 18.4.3. Submittal Date: Fri Jul 19 11:32:42 EDT 2013 Committee Statement: The TC deletes the text based on the changes that were made to 18.4.1.4. Refer to FR-81.
