3 33 March 27, 2014, “Overcoming Hurdles to Ensure In-Building Communications” In-building Communications are Vital to Emergency Responders Allows first responders to go ‘where the action is’ Direct communication to the 911 dispatcher, incident commander (IC), or hospital ER Other responders can hear what is going on for ‘situational awareness’ Allows first responders to go ‘where the action is’ Direct communication to the 911 dispatcher, incident commander (IC), or hospital ER Other responders can hear what is going on for ‘situational awareness’

8 88 March 27, 2014, “Overcoming Hurdles to Ensure In-Building Communications” Regulatory Many have touched the issue, but few were ANSI certified standards bodies –NPSTC: white paper issued in 2007: www.npstc.org/inBuilding.jsp –NTIA (TR-11-480) and NIST issued several white papers in 2011 NFPA is a logical place for codes and standards because the driver in most jurisdictions is the fire department Many have touched the issue, but few were ANSI certified standards bodies –NPSTC: white paper issued in 2007: www.npstc.org/inBuilding.jsp –NTIA (TR-11-480) and NIST issued several white papers in 2011 NFPA is a logical place for codes and standards because the driver in most jurisdictions is the fire department

9 99 March 27, 2014, “Overcoming Hurdles to Ensure In-Building Communications” Multiple Standards & Codes NFPA 1 (Fire Code) NFPA 72 (Fire Alarm Signaling Systems Code) NFPA 1221 (Emergency Services Communications Systems Standard) NFPA 5000 (Building Construction & Safety Code) International Fire Codes NFPA 1 (Fire Code) NFPA 72 (Fire Alarm Signaling Systems Code) NFPA 1221 (Emergency Services Communications Systems Standard) NFPA 5000 (Building Construction & Safety Code) International Fire Codes

10 10 March 27, 2014, “Overcoming Hurdles to Ensure In-Building Communications” Issues with Current Standards & Codes Conflicts among the standards/codes Do not cover digital LMR radios (e.g., P25, OpenSky, TETRA, DMR. etc.) Do not anticipate future broadband technologies (e.g., FirstNet public safety LTE system) Are signal booster and leaky coax centric; do not cover newer technologies (DAS, Radio over Fiber, etc.) Conflicts among the standards/codes Do not cover digital LMR radios (e.g., P25, OpenSky, TETRA, DMR. etc.) Do not anticipate future broadband technologies (e.g., FirstNet public safety LTE system) Are signal booster and leaky coax centric; do not cover newer technologies (DAS, Radio over Fiber, etc.)

13 13 March 27, 2014, “Overcoming Hurdles to Ensure In-Building Communications” What is Being Done NFPA 72 now in revision –Will remove specifics on in-building, and will refer to NFPA 1221 for all specifics –Many jurisdictions already mandate compliance to 72 because it is a code, so local references to 72 will still end up being reflected back to the 1221 standard NFPA 72 now in revision –Will remove specifics on in-building, and will refer to NFPA 1221 for all specifics –Many jurisdictions already mandate compliance to 72 because it is a code, so local references to 72 will still end up being reflected back to the 1221 standard

14 14 March 27, 2014, “Overcoming Hurdles to Ensure In-Building Communications” What is Being Done NFPA 1221 now in revision –Better suited to define details because committee is composed of wireless experts –Several DAS industry vendors were polled for input –Remember NFPA codes and standards are minimums NFPA 1221 now in revision –Better suited to define details because committee is composed of wireless experts –Several DAS industry vendors were polled for input –Remember NFPA codes and standards are minimums

15 15 March 27, 2014, “Overcoming Hurdles to Ensure In-Building Communications” What is Being Done NFPA 1221 now in revision-new section 9.6 replaces previous in-building work –Adds reference to DAS as a solution, in addition to leaky coax –Testing is no longer to -107 dBm RF signal level, but rather to Delivered Audio Quality (DAQ) for either analog or digital systems, minimum of 3.0 –Battery life is 4 hours minimum. Appendix suggests AHJ might want to specify more. –Isolation to donor antenna increased to 20 dB NFPA 1221 now in revision-new section 9.6 replaces previous in-building work –Adds reference to DAS as a solution, in addition to leaky coax –Testing is no longer to -107 dBm RF signal level, but rather to Delivered Audio Quality (DAQ) for either analog or digital systems, minimum of 3.0 –Battery life is 4 hours minimum.

16 16 March 27, 2014, “Overcoming Hurdles to Ensure In-Building Communications” What is Being Done NFPA 1221 now in revision –First Draft (previously known as ROP) work completed and voted upon in February –Second Draft (prev. Report on Comments-ROC) work will be later this year –1221 will be voted upon by NFPA in 2015, issued in 2016 –View current work at: www.nfpa.org/codes-and- standards/document-information- pages?mode=code&code=1221&tab=nextedition NFPA 1221 now in revision –First Draft (previously known as ROP) work completed and voted upon in February –Second Draft (prev.

17 17 March 27, 2014, “Overcoming Hurdles to Ensure In-Building Communications” What is Being Done In future NFPA 1, 5000 will all refer to NFPA 1221 for details, to prevent overlap and ‘code shopping’ It is expected that the IFC will follow suit with 1221 over time In future NFPA 1, 5000 will all refer to NFPA 1221 for details, to prevent overlap and ‘code shopping’ It is expected that the IFC will follow suit with 1221 over time
