BDA/DAS Solutions Public Safety In-Building Safety Communications

A noteworthy development is the recent changes in codes that mandate all new buildings to achieve a minimum signal strength level (-95 dBm) for fire, police, and EMS radio signals. Compliance requires signal levels to be assessed and recorded within designated zone sizes on each floor by an FCC licensed and factory-certified professional.

These measurements must then be documented and submitted for approval to the AHJ (Authority Having Jurisdiction). In cases where any floor falls below the minimum signal threshold, the installation of a BDA system (also known as ERCES) becomes mandatory. These systems can exclusively be implemented by installers licensed by the FCC, such as Maximum Fire and Security.

Furthermore, the code stipulates that these systems undergo annual re-inspections or when significant renovations take place within the building. Emergency Radio Communication Enhancement Systems (ERCES), or BDAs, were initially introduced in the 2009 International Building Code. Contemporary codes, including IBC 2015 Section 916 and the 2018 International Fire Code (ICC IFC-2018) Section 510, NFPA 72 2010, NFPA 1221 2016, and UL2524, now demand that all new constructions provide approved radio coverage for emergency responders within the premises.

For instance, in North Carolina, Section 510 of the 2018 N.C. Fire Prevention Code necessitates a final signal strength assessment for Emergency Responder Radio Coverage in all new construction projects. The role of ERCES (BDAs) is pivotal in ensuring comprehensive radio signal reception throughout the building, encompassing crucial areas like basements, stairwells, and other critical zones. This unimpeded communication network is essential for the effective coordination of first responders during emergencies.
