13 Task Group Report on Physical Properties of Land Mobile Radios Teleconference Conference Call April 17, 2013 Members on the Call: Mike McKenna, Michael McKenna & Associates, LLC, Task Group Chair Matt Bowyer, NIOSH Jose Velo, San Francisco Fire Department Rex Strickland, Fairfax Fire & Rescue Jim Greene, Boston Fire Shane Bray, MSA Ed Cortes, Icom America Matt Busa, Motorola John Oblak, EF Johnson Technologies Michael Feely, Boston Fire Dave Stoddard, Michael McKenna & Associates, LLC This list of items takes into account that the Task Group eliminated some of the original list and combined other items. The next Task Group report will have an updated item list. Item #1 Radio Channels Discussion regarding the large variation in channels between radios and radio systems somewhere between 48 and 2,000. Included was a discussion that there are at least two different terms for the same functions. Channels/Zones and Decks/Banks. Task Group to develop common terms for Channel/Zone or Deck/Bank Deferred to manufacturers to come up with a workable minimum. Manufacturers to help supply what a minimum number of radio channels for a minimum standard. This will have to be coordinated with the Task Group on Feature Sets as that TG will determine the number of channels, etc. and this TG will adjust the physical properties to accommodate the decision. Item #2 Remote Mic Item #2, Item #9, Item 15 and Item #20(added during the call) were combined into one item and the features that will be included on the remote mic will be developed. Issues discussed include: 2
14 Visible Transmission Indicator TG to investigate and report back on an indicator on the radio and the remote mic that a firefighter can see Radio Failure Alert TG to investigate and report back on the possibility of a tone when radio components are damaged. Manufacturers stated that there is currently an alert when the wires are severed, but it might not work if the wires are melted. Visible Transmission Channel TG to investigate and report back on an indicator on the radio and the remote mic that a firefighter can see Item #3 Emergency Activation Task Group is researching and reporting back on different methods to activate the emergency activation including: Modifying the current system with bigger and differently protected single button and the possibility of incorporating a timer into the activation similar to the activation of PASS Use of a two-button system may work, but questions about transmission buttons being in the way or counter intuitive to the current single button system. TG members from the fire service reiterated that the system must be universal Item #4 LMR Based Local PASS Task Group liked the concept, but was concerned about interference when listening and transmitting. Held for further study. Item #5 Remote Mic Task Group is researching and reporting back on the desired features of the remote mic including: Channel Selector Visual Channel Indicator Voice Channel Announcement Transmit Indicator Emergency Button Test Method for the strength of the attachment clip (See Item #19) Concerns that the desire of the Task Group is to keep the remote mic as small as possible, with these features and large enough to use with NFPA 1971 certified structural gloves 3
15 Item #6 Remote Mic Cord Task Group desires some type of flexibility requirement for the mic cord and will work with the Environmental Conditions Task Group Task Group desires thermal stability testing and the fire service members would like to include the thermal stability testing of 500F for 5 minutes. Item #7 Universal Interface Task Group will research and report back on some type of industry universal interface for communications between the LMR and the SCBA facepiece. This will include wired systems, wireless systems and universal attachments and hardware as necessary. Item #8 Carrying Holster Tabled at this time. Item #9 Radio/Remote Mic Transmission Interface Incorporated into Item #2 Item #10 Audio Intelligibility Task Group had a lengthy discussion about various ways to determine intelligibility of the radio and the remote mic The Task Group is researching and will report back and items to be researched include: P25 Current encoders Setting minimum sound pressure levels or electrical power to determine intelligibility Item #11 Antenna Tabled as the TG feels this issue is covered by IP67 requirements 4
16 Item #12 LMR Status Item #13 Remote Mic Status Item #14 Home Screen or Main Channel Activation Task Group believes that these items belong to the Task Group on Feature Sets and will coordinate any physical properties that need to be incorporated. Item #15 Visual Channel Indicator Incorporated into Item #2 Item #16 Hands free Use Tabled as the Task Group did not believe the technology was currently available for this to practical. Item #17 Channel Selectors Item #18 Two-Position Selector Switch Incorporated into Item #1 Item #19 Remote Mic Radio Security Task Group believes that there have been issues in the past with the remote mic clips breaking. Task Group believes that a test method needs to be developed to test the mic clip retention. Item #20 Radio Failure Alert See Item #2 5
17 TG on Physical Properties Task Group Report 1 Task Group Report on Physical Properties of Land Mobile Radios Teleconference Conference Call July 11, 2013 Participants on the Call: Mike McKenna Matt Bowyer Jose Velo Rex Strickland Jim Greene Shane Bray Scott Glazer Matt Busa John Rehaymen Steve Weinstein Scott Major Michael McKenna & Associates, LLC, Task Group Chair NIOSH San Francisco Fire Department Fairfax Fire & Rescue Boston Fire MSA Thales Communication Motorola Otto Excellence Honeywell First Responders Somerville Fire This list of items takes into account that the Task Group eliminated some of the original list and the items have been renumbered. Item #1 Radio Channel Selectors TG discussed the importance of making sure that the channels were designed for safe navigation after Task TG on Features sets the direction. Item #2 Remote Mic Task Group is still researching and will report back on the desired features of the remote mic including: Channel Selector Visual Channel Indicator Voice Channel Announcement Transmit Indicator Emergency Button Test Method for the strength of the attachment clip (See Item #7) Concerns that the desire of the TG is to keep the remote mic as small as possible, with these features and large enough to use with NFPA 1971 certified structural gloves In addition, these features of the remote mic remain the center of discussion: 1. Visible Transmission Indicator TG to investigate and report back on an indicator on the radio and the remote mic that a firefighter can see 6
18 TG on Physical Properties Task Group Report 2 2. Radio Failure Alert TG to investigate and report back on the possibility of a tone when radio components are damaged. Manufacturers stated that there is currently an alert when the wires are severed, but it might not work if the wires are melted. 3. Visible Transmission Channel TG to investigate and report back on an indicator on the radio and the remote mic that a firefighter can see. The possibility of using a photo diode to manage illumination was also briefly discussed. In addition, TG would like to see the entire Remote Mic added to the thermal testing and also add some type of requirement for direct flame impingement. There was also discussion about a European test method that could be incorporated that subjects the components to 300 C (572 F) for 3 minutes Item #3 Emergency Activation Task Group discussed and will report back on different methods to activate the emergency activation including: 1. Modifying the current system with bigger and differently protected single button and the possibility of incorporating a timer into the activation similar to the activation of PASS 2. TG members from the fire service reiterated that the system must be universal In addition, TG is considering that there be requirements for both the remote mic and the radio, not just the radio. TG discussed the use of a time to reduce false alerts and enable a larger emergency button. Item #4 Remote Mic Cord Task Group desires some type of flexibility requirement for the mic cord and will work with the Environmental Conditions Task Group Task Group desires thermal stability testing and the fire service members would like to include the thermal stability testing of 500F for 5 minutes. There was also discussion here about a European test method that could be incorporated that subjects the components to 300 C (572 F) for 3 minutes Item #5 Universal Interface Task Group will research and report back on some type of industry universal interface for communications between the LMR and the SCBA facepiece. This will include wired systems, wireless systems and universal attachments and hardware as necessary. Shane Bray is going to research this and report back to the TG. 7
19 TG on Physical Properties Task Group Report 3 Item #6 Audio Intelligibility Task Group had a lengthy discussion about various ways to determine intelligibility of the radio and the remote mic The Task Group is researching and will report back and items to be researched include: P25 Current encoders Setting minimum sound pressure levels or electrical power to determine intelligibility Steve Weinstein will research the use of sound pressure tests similar to NFPA Item #7 Remote Mic Radio Security Task Group believes that there have been issues in the past with the remote mic clips breaking. Task Group believes that a test method needs to be developed to test the mic clip retention. Mike McKenna and NIOSH/NPPTL are doing testing on structural turnout mic tabs to test their breaking strength to determine proper retention force. 8

21 Meeting minutes of TG on environmental testing conference call held at 10:00 am on June 26, 2013 Members Present Michael Feely Jeffery Hull Kate Remley William Young James Rose Craig Gestler John Morris Boston Fire Department DC Fire Department NIST NIST SEI MSA ISGfire The goal of the TG meeting was to develop beginning environmental tests for LMRs. The TG went through a list of environmental tests that was generated at the last TC meeting on ESE. Members reviewed the current details of the same tests that currently exist in the SCBA, PASS, and TIC standards. The TG developed a list of basic functions that should work after the environmental testing. Basic Functions Transmit Receive PTT Emergency Button Display Channel selector Channel announce LED indicators Speech Transmission Index (STI) The following is a list of the current test proposals. 1. Radio system Point to point attenuation This is a success or failure test from PASS. With LMRs the signal can become gradually weakened and we need a test to determine how much attenuation is acceptable. This test may help ensure the transmit/receive items in the basic functions list. A possible testing protocol may be the current Speech Transmission Index (STI) test from SCBA. Kate Remley will investigate a possible method to determine acceptable signal loss. 2. Radio system Loss of signal This test was taken from PASS doc. and should be copied. TG believes that this would be easy to do with a digital radio system, and currently exists when on a trunked radio when lines are busy. It may be more difficult with analog radios. Will need input from radio mfg s. to develop test. 3. Radio system Interference test Used for unlicensed radios (PASS) and probably not applicable to licensed radio systems. There may be a current radio standard that addresses this issue. Need input from radio mfg s. 2
22 4. Frequency drift narrow banding There may exist a test that we could use. Bill Young & Kate Remley will investigate. Kate has found measurement and performance standards for this issue in TIA-603C, and TIA-102 CAAB documents. We can have a detailed explanation of these tests from the radio manufacturers. 5. Electromagnetic compatibility (EMC) This is a European test (IEC61000 part 6-2, 6-3). The FCC may have regulations that are now met by the radio mfg s. Bill and Kate will research. Mfg s can provide specifics. Kate will check with a contact at Public Safety Research Lab for current standards that may apply. 6. Environmental temperature performance test (SCBA) / Electronic temperature stress test (PASS). These tests are very similar except the temperature values are different. (Hot, cold, hot to cold, cold to hot)tg feels that Electronic temperature stress test is a more appropriate name because it is testing electronic equipment. The TG feels we should start with the values in the SCBA test because they are more extreme. There were no members from radio manufacturers on the conference. At the next TC meeting they can provide input on the current temperature performance ranges of the radios. 7. Lens abrasion This is a current TIC and facepiece test that is easy to accomplish. TG recommends that it is copied from these standards. 8. Vibration resistance performance test This is the current package tester procedure. TG recommends that this test be incorporated into the LMR standard. 9. Tumble vibration test This is a PASS test. The Durability test for TIC is similar and includes hot, cold, and water dunk components. The TG feels that we could combine these tests and the durability test would be a better starting point. TG also recommends removing the 49C/60C/49C/60C temp cycle and starting with a higher temperature for a longer period of time, before tumbling. This test should also include using a water foam solution for dunking at 1m. 10. Heat and emersion leakage This test is similar to the durability test. In the durability test the product is at elevated temps for hours whereas in this test the product is at a greater elevated temp (350) for only 15 minutes. In the elevated temp performance test (#11) the product is at the highest temp (500⁰F) for 5 minutes. It may be possible to eliminate this test because we have the new durability test with higher temps. We are testing for water leakage in this test. We would have to add this component to the durability test along with basic functions for the LMR to pass. 11. Elevated temperature performance test This is the 500⁰F for 5 minutes test found in all three standards. TG recommends copying this test from the other standards and testing for basic functions. 12. Lens radiant heat performance test This is for SCBA facepiece and not applicable to LMR. 3
23 13. Particulate resistance performance This is an SCBA test and similar to the Ingress protection (IP) test for TIC. Because PASS and TIC require an IP rating of IP6X we should start here. This test may be unnecessary because of the durability test. (#9 above) 14. Impact acceleration resistance Currently two tests exist. PASS drop from 3m, TIC drop from 2m. Item is preconditioned at elevated temperature of 60⁰C (140⁰F) for four hours and dropped eight times. TG recommends copying the PASS test. 15. Corrosion resistance performance TG recommends that the LMR standard contain the same test found in the other three standards. 5% salt spray at 35⁰C for 48 hrs, then salt spray at 22⁰C for 48 hrs, then test functions. 16. Case integrity TG believes this test can be copied from the PASS standard. 200kg (442lbs) placed on each surface for 1 minute. Need to work on surface that contains the antenna. 17. Cable pull out This is a TIC test; however similar tests exist for PASS and SCBA. The forces applied in the three standards are all different. 89N, 156N, and 45N-445N. These forces also need to be applied to the RSM retention clip as well as the antenna. The TG believes we should start the force at 220N. 18. Heat and flame test This test is identical in the SCBA, PASS, and TIC standard. The TG recommends that we use this test as is in the LMR standard. Direct flame contact for 10 seconds, after flame must be < 2.2 seconds. No parts can fall off. 19. Product label durability Copy from TIC standard 20. Speech intelligibility Use the STI test for the amplifier from NFPA This test measures the octave difference between points. 21. Water drainage test This test can be copied from the PASS standard and then apply the STI test for pass/fail. 22. MIL 810 Need input from radio manufacturers to determine if current proposed tests will be sufficient to meet or exceed this requirement. 23. Common chemical exposure 4
24 This is a NFPA 1971 garment test (ASTM F903). It would be possible to use the same chemicals and apply them to the radio case to check for degradation similar to the current facepiece tests for CBRN agents.
