• BOCA National Building Code – 1993 Edition – Section 403.0
• 2009 IFC – 510.1 Emergency responder radio coverage in buildings.
• All buildings shall have approved radio coverage for emergency responders within the building based upon the existing coverage levels of the public safety communication systems of the jurisdiction at the exterior of the building. This section shall not require improvement of the existing public safety communication systems.
• Exceptions: 1. Where approved by the building official and the fire code official, a wired communication system in accordance with Section 907.2.13.2 shall be permitted to be installed or maintained in lieu of an approved radio coverage system.
Automatic Fire Alarm Association
IFC, 2009 Appendix J
• Appendix J Emergency Responder Radio Coverage.
• This new IFC Appendix provides design, installation, testing and maintenance requirements for the emergency responder communications facilities where required by new IFC Section 510. Included are requirements for system performance, primary and secondary power supplies, signal boosters, radio frequencies, installer qualifications, acceptance testing and system maintenance. Note that the provisions contained in this appendix are not mandatory unless specifically referenced in the adopting ordinance.

• Transmit power. The power
that is broadcast by the
transmitter. This is usually
measured in watts or milliwatts.
• Receive sensitivity. A measure
of the minimum signal strength
that a receiver can discern.
• Antenna gain. The amount of
signal gain provided by the
antennas.
• Path loss. The signal decrease
that occurs as the radio waves
travel through the air or
through obstacles.

Passive vs Active Distributive Antenna Systems
Passive DAS
• Fed with public safety repeaters
• Amplifiers (repeaters) are in one location
• RF distributed over coax to antennas throughout building or area
Active DAS
• Fed with public safety repeaters
• Optical fiber distribution system
• Distributed amplifiers
• Low power and high power solutions depending on coverage and capacity requirements

NFPA 1221 - 2019
Pathway SurvivabilityThe 2019 and 2016 with the TIA say basically the same thing. What has changed is the terminology.
• Riser is now called backbone in the 2019 code (see definition in section 3.3.10 of 1221 2019 edition) Backbone: A communications cable in an in-
building radio enhancement system that carries wideband signals important to the entire building, from the donor antenna, through the amplifiers, and to distribution antenna lines.
• Feeder cable is now called distribution antenna cable: A communications cable that carries RF energy in both directions along its length to distributinantennas in one or more places in the building.

• Location of the donor antenna(s)
• Types of systems• Leaky coax
• DAS
• Repeater
• Others

Inspection
• Coordinate testing with emergency responders
• Test using actual equipment
• Analog equipment verification of pass / fail criterial is easier to verify than Digital
• Verify signal monitored
• Test using secondary power
