The Building Code (IBC/CBC) specifies Where and When Two-Way Communications Systems are required in buildings. Such as IBC-2018 Section 403.5.3.1 includes requirements for “Stairway Communication System”, Section 1009.6.5 includes requirements for “Areas of Refuge Two-Way Communication”, Section 1009.8 Include requirements for “Elevator Landing Two-Way Communication System” and CBC-2019 Section 1010.1.9.12 includes requirements for Locked Elevator Lobbies. Also the IFC-2018 and CFC-2019 Section 510 and CBC-2019 Section 916 includes requirements for Emergency Responders Radio Coverage in NEW and EXISTING buildings.

The NEW specific code requirements for the design, installation and performance of these Two-Way Emergency Communication Systems (ECS) and ERRCS are specified in NFPA 72-2019 and NFPA 1221-2019.

Reliable communication between first responders (Police and Fire) during emergency events is essential to provide better management and control of the event. For many years, these systems were based on wired technology such as phone-jacks and emergency (Fire Wardens) phones; however, based on first responders’ feedback, it was determined that they prefer to use their personal portable radios for communication during emergency events. Emergency Responders Radio Coverage Systems (ERRCS) were first required by the 2009 IFC and associated NFPA standards 2009 NFPA-5000 and the 2010 NFPA-72. This presentation will discuss and clarify current IBC and IFC codes and specific NFPA installation and performance requirements from the perspective of enforcing agencies/AHJ.

This class will focus on the NEW 2019 Code requirements for in-buildings Two-Way Emergency Communications Systems (ECS) in NFPA 72-2019 and NFPA 1221-2019 which will become effective in CA on January 1st 2020, when the the 2019 CBC and CFC will become effective in CA. NFPA 72 Section 24.10 was completely revised in the 2019 Edition: The following ECS were combined under this Section: Area Of Refuge (AOR), Stairway, Elevator Landing, and Occupant Evacuation Elevator Lobby. Other Two-Way ECS were removed and relocated to the Annex (Elevator ECS) and other sections were rearranged (Section 24.11 and 24.12). CBC-2019 also includes specific CA requirements for locked elevator lobbies Access Control and specific associated ECS. NFPA 1221-2019 (Specific Sections) is the current NEW national applicable code for ERRCS and it includes new requirements for all ERRCS system components monitoring, supervision, survivability, etc. Specific Pathway Survivability Levels requirements for conduits, cables, wiring per NFPA 72 Chapter 12 and NFPA 1221 and Examples from actual designs will be presented and discussed in this Class.


  1. After attending this session participants should be able to define and understand the differences between One-Way and Two-Way Emergency Communications Systems.
  2. Identify the various types of Two-Way Emergency Communications Systems included in NFPA 72 Chapter 24 and determine in which buildings these systems are required based on the 2018-IBC and 2019 CBC/CFC.
  3. Define and understand ECS and ERRCS associated code terms such as Pathway Survivability Levels, Voice Intelligibility, and System Supervision.
  4. Understand and learn how to apply specific NFPA 72-2019 Chapters 12 and 24 installation and performance requirements to new ECS projects, based on enforcement agencies/AHJ’s requirements.
  5. Understand the specific 2018 IFC/IBC requirements for Emergency Responders Radio Coverage (ERRC) versus Emergency Responders Radio coverage Systems (ERRCS) in various types of existing and new buildings.
  6. Discuss new Supervision and Monitoring requirements for ERRCS per NFPA 1221-2019: Standard for the Installation, Maintenance, and Use of Emergency Services Communications Systems.
