AGENDA ITEM 6; NFPA 1982 PASS SOUND TASK GROUP REPORT AND REVIEW OF RECOMMENDATIONS FOR PROPOSED CHANGE Craig Gestler, Chairman of the PASS Sound Task Group, presented a report on the work the Task Group has done to develop a new standardized PASS sound. His presentation covered the history of the issue and the testing work recently done at Intertek and NIST to validate the proposed 2018 PASS sound. The recommendation of the Task Group is to continue to move forward with the sound proposed in the First Revision of NFPA 1982. The SCBA manufacturers (Scott, MSA, Honeywell, Avon, Dräger and Interspiro) then demonstrated their PASS devices three different ways: (1) A 2013 PASS sound set at the current 2013 minimum requirement of 95 dba peak response at 3 meters (2) A 2018 PASS sound detuned to the proposed 2018 minimum requirement of 92 dba fast response at 1 meter (3) A 2018 PASS sound representing a normal 2018 production unit AGENDA ITEM 7; REVIEW OF PUBLIC COMMENTS FOR NFPA 1801 The TC reviewed and acted upon Public Comments submitted for NFPA 1801. The TC created Second Revisions based on those actions and additional committee actions. AGENDA ITEM 8; NFPA 1802 DRAFT DEVELOPMENT The TC continued its review and revision of NFPA 1802. Chairman Athanas directed Mike McKenna, Chairman of the Task Group on Chapter 6, to have a solution for a universal connector, taking into account intrinsic safety, by September 15. Chairman Athanas asked the TC members to communicate with Chairman McKenna regarding any issues or suggestions by that date. Chairman Athanas directed Steve Townsend, Chairman of the HazLoc Task Group, to have a solution for intrinsic safety developed by September 15. This could include requiring Division 2 certification instead of Division 1. Chairman Athanas asked the TC members to communicate with Chairman Townsend regarding any issues or suggestions by that date. It is up to the Task Group Chairmen to ensure that all appropriate TC members participate in the development of solutions, even if they are not currently members of the Task Groups. AGENDA ITEM 9; OLD BUSINESS Acting Secretary Steve Weinstein reminded all Task Group Chairmen that Task Group meetings should occur on a scheduled basis in between Technical Committee meetings. The Technical Committee is not responsible for performing a Task Group s discussion and editing function at a full TC meeting. The Task Group should present at a TC meeting what is intended to be a final version of the sections of the standard that fall within their jurisdiction. This includes content, NFPA standard language, grammar and punctuation. The TC should be able to review the Task Group s work and determine whether it is acceptable, or whether it needs to Page 3 of 4
be further revised. Such revision may be accomplished at the TC meeting, or it may need to be done through additional, subsequent meetings of the Task Group. A Task Group Chairman attending a TC meeting with no work having been undertaken since the last TC meeting, under the assumption that the TC will perform that work, is not acceptable. AGENDA ITEM 10; NEW BUSINESS Chairman Athanas reminded the TC that the next meeting will be held on December 6-8 in San Diego, CA. AGENDA ITEM 11; ADJOURNMENT MOTION BY MIKE HUSSEY; SECOND BY BRIAN MARTENS To adjourn. MOTION CARRIED. Chairman Athanas adjourned the meeting at 13:15 on 14 July 2016. Respectfully submitted, Steven H. Weinstein, Acting Secretary Technical Committee on Electronic Safety Equipment Page 4 of 4

2 of 13 11/18/2016 9:37 AM Public Comment No. 4-NFPA 1982-2016 [ Section No. 4.1.9 ] 4.1.9 The certification organization shall require manufacturers to remove all certification labels and product labels indicating compliance with the 2013 edition of this standard from all PASS that are under the control of the manufacturer on August 31, 2018 12 months from the effective date of this revision of the standard. The certification organization shall verify this action is taken. TC agreed to change to 12 months to align with other standards and to prevent multiple TIAs as experienced in the 2013 revision.

3 of 13 11/18/2016 9:37 AM Public Comment No. 15-NFPA 1982-2016 [ Section No. 5.1.8 ] 5.1.8 PASS also shall be labeled as certified at least to the requirements for Class I, Groups C and D; and Class II, Groups E, F, and G; Division 1 hazardous locations specified in ANSI/UL 913, Standard for Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1 Hazardous (Classified) Locations. Where an acceptable alterna ve hazardous loca ons Intrinsic Safety standard has been used, the alterna ve hazardous loca ons marking shall be shown clearly on the product approval label as specified by the agency performing the tests. Opens the use of later or equivalent intrinsic safety standards. For this standard, UL913 ed. 6 has been confirmed to provide sufficient protection for the application. This edition has been superseded by edition 7th and later 8th editions which are equivalent to the IEC60079/EN60079 series of standards. To open the approval path of PASS to NFPA1982 to secure alternative routes and in support of continuous improvements in product developments, extra wording is required in the 2018 revision to allow the approval agency to follow in an open manner. The current wording requires the testing and certification to the 6th edition of UL913 however there is no acceptable clause to permit the manufacturer to receive approval to at least the same minimum locations by using the later editions of the same standard or to the IECEx/EN 60079 series of standards which are equivalent to the later editions of UL913 calling up the UL equivalent of the IEC60079 series of standards. It is reasonable to permit the certification to later or equivalent intrinsic safety standards and not have to also receive certification to the 6th edition.

4 of 13 11/18/2016 9:37 AM Public Comment No. 14-NFPA 1982-2016 [ New Section after 6.4.3.9.6.3 ] Use of Silent Intervals The PASS shall be permitted to incorporate a supplementary alarm signal or signals in addition to those indentified in the 8 steps of section 6.4.3.9. In particular, the silent intervals identified as steps (2), (4), and (8) in section 6.4.3.9 may be used to further enhance the detection and recognition of the alarm sequence, and/or to improve the ability of a rescuer to navigate to the location of the PASS. Such supplementary alarm signals shall meet the specific time requirements in section 6.4.3.9. The alarm sequence approved for the 2013 Edition of NFPA 1982 had very tight tolerances for the frequencies and timing of the steps. Difficulties were encountered by the manufacturers in achieving the necessary Sound Pressure Level and in meeting the tight tolerances. As a result, the tolerances were relaxed and the specific frequencies were allowed to be different for different manufacturers. An on-going development program to enhance the detection and recognition of an alarmed PASS by means of electronic devices requires detailed knowledge of the exact sound of the PASS. It has been demonstrated that electronic detection of an alarm sound at -35 to -40 db relative to typical background sounds is possible. By comparison, detection by the human ear is limited to the range of -15 to -20 db relative to typical background sounds. Thus electronic detection is possible when the PASS is completely inaudible to the human ear. Furthermore, it has also been demonstrated that electronic detection can be further enhanced to determine the direction of the PASS. A navigation/location system for firefighter rescue which uses electronic detection of the alarm sound is currently under development. Unfortunately, the relaxing of the frequency requirements and tolerances renders such an electronic system virtually inoperable. The proposed modification of the alarm sequence whereby the silent intervals in steps (2), (4), and (8) are used for supplementary alarm sounds would allow the PASS to be detected by the electronic navigation/location system. Since the sounds in the remaining five steps are unchanged, the proposed modification would not affect the frequency tolerance requirements nor reduce the overall Sound Pressure Level of the PASS. Thus the proposed modification would have virtually no effect on the ability of a manufacturer to meet the design requirements of the PASS. On the other hand, the benefits of allowing manufacturers to use the silent intervals to enhance the detection of the PASS when not otherwise humanly possible, and to enhance the ability to navigate to the location of a disabled firefighter cannot be understated. The bottom line: an operational navigation/location system will save lives.

5 of 13 11/18/2016 9:37 AM Public Comment No. 5-NFPA 1982-2016 [ Section No. 6.4.4 ] 6.4.4 Low Power Source Warning Signal. 6.4.4.1 While in the sensing mode, PASS shall emit a recurrent audible low power source warning signal when the power source voltage or power source percent capacity remaining is depleted to the level that will maintain the alarm signal level of at least 95 dba for at least at a minimum of 92 dba for a minimum of 1 hour. 6.4.4.2 The power source shall be discharged at a rate that is equal to the average current draw, ±10 percent of the same model PASS, while in the alarm mode. The rate shall be determined by measurement by the certification organization. 6.4.4.3 The low power source warning signal sound shall be distinct and different from the pre-alarm signal(s) and the alarm signal. 6.4.4.4 The low power source warning signal shall have an interval of not greater than 30 seconds. 6.4.4.5 While in the off mode and with the power source voltage or power source percent remaining at or below the level specified in 6.4.4.1, the system that causes the activation of the low power source warning signal shall cancel the operational signal so that it shall not sound when the PASS is switched to the sensing mode. With the introduction of rechargeable batteries to the SCBA/PASS alarms, it has become very difficult to determine the low battery point by only measuring the battery voltage. Alkaline batteries have a linear, sloping discharge curve and the remaining battery capacity can be determined from the measured voltage. Rechargeable cells, however, have a very flat voltage discharge curve and it is nearly impossible to accurately determine remaining capacity from the voltage measurement. Most rechargeable batteries are used in conjunction with "gas gauge" chips which accurately measure the charge moving in and out of the cell and make an accurate assessment of the remaining battery capacity.

7 of 13 11/18/2016 9:37 AM Public Comment No. 9-NFPA 1982-2016 [ Section No. 7.1.1.1 ] 7.1.1.1 PASS shall be tested for the sound pressure level of the audible primary pre-alarm signal as specified in Section 8.2, Sound Pressure Level Tests. The sound pressure level of the Type 1 tone pair shall be between a minimum of 80 dba and 95 dba. The sound pressure level of the Type 2 tone pair shall be between a minimum of 86 dba and 104 dba and shall be at least 6 db a minimum of 3 dba greater than the Type 1 tone pair. The sound pressure level of the Type 3 tone pair shall be between a minimum of 100 dba and 110 dba and shall be at least 6 db a minimum of 3 dba greater than the Type 2 tone pair. The test for the pre-alarm is very difficult to perform and is very unrepeatable. The measurement method for the full alarm was changed (with the TIA) from a 3m radius using the "peak" response function on the SPL meter to a 1m radius using the "fast" response function on the SPL meter. This change seeks to align the pre-alarm test method with the full alarm test method. The actual db values were found to be comparable to the db values in the old method and do not need to change.

The class and division specified using UL913 edition 6 is the minimum acceptable standard acceptable to claim compliance to this edition of the standard. It is acceptable to choose an alternative to UL913 edition 6 for the same or equivalent protection class and division to support the continuous improvements in product development where they have and can exceed the minimum or where an equivalent standard is used to achieve the certification whilst maintaining the minimum hazardous locations specified. The manufacturer is advised to provide an equivalency statement that must be provided to the certification organisation. Examples of this are where [1] additional gas groups approval have been achieved (e.g. group B or groups A & B), or [2] where a later edition of the same standard has been used such as edition 7 or 8, or [3] an alternative standard has been used that can be shown to provide at least the same or in excess of the minimum such as IEC60079 or EN60079 series of standards.
