Clear, reliable communication during emergencies is critical. As of January 2025, existing buildings across Florida will be required to install Bi-Directional Amplifier (BDA) systems to meet updated emergency radio communication and fire code regulations. Far more than a routine code change, this new rule enhances life safety by helping first responders stay connected and ensuring buildings are ready for the unexpected.
Why Your Building Needs a BDA System
When emergencies happen inside a building, first responders (firefighters, police officers, medical services, etc.) must be able to communicate instantly and clearly. However, buildings often use materials that interfere with radio signals. Concrete, steel, Low-E glass, and other dense or energy-efficient construction elements can weaken or block critical radio frequency (RF) signals, creating blind spots where communication is lost.
This presents serious risks during fire, medical, or security incidents where every second counts.
Emergency Responder Communication Enhancement Systems (ERCES) solve this problem. It uses bi-directional amplifier Systems (BDA) and distributed antennas to boost and relay radio signals throughout the building—ensuring responders stay connected no matter where they are.
Key Benefits
The Value of Installing a BDA System
A professionally designed and installed BDA system provides:
- Reliable and strong radio coverage throughout the building
- Uninterrupted communication for fire, police, and EMS personnel
- Signal penetration through walls, glass, and structural barriers
- Improved life safety and faster emergency response
- Full compliance with Florida and national fire and building codes
- Code-required coverage levels
- Certified signal boosters and Distributed Antenna Systems (DAS)
- Peace of mind for building owners, tenants, and emergency professionals

Understanding Florida Code & Compliance
Florida Fire Prevention Code & Statute § 633.202
Florida law gives the Authority Having Jurisdiction (AHJ) the right to require adequate radio signal strength inside any new or existing building. If a structure does not provide strong, consistent signal coverage, a BDA system may be required.
Florida Statute § 633.202 also allows certain building types to request compliance extensions, but this does not exempt them from eventual compliance.
Building owners should proactively assess their properties to avoid delays, enforcement actions, or costly retrofits later on.
NFPA 1221: Standard for the Installation, Maintenance, and Use of Emergency Services Communications Systems
Under NFPA 1221 Section 9.6.7.3 and 9.6.7.4, the following minimum performance standards must be met:
- 90% coverage in all general building areas
- 99% coverage in critical areas such as stairwells, basements, fire command centers, and elevators
- A minimum inbound and outbound signal strength of -95 dBm, or as otherwise determined by the AHJ
- Use of certified signal boosters and DAS if minimum signal strength or coverage levels are not met
These standards ensure that first responders have the radio support they need inside complex, high-density, or tall structures.
Past the Deadline? Here's What to Do Now
Whether you manage residential high-rises, commercial properties, or mixed-use developments, you need to assess your building’s readiness.
Early action saves time and reduces risk. Conducting a radio frequency (RF) survey now can help determine whether your property needs a BDA system, identify any weak signal areas, and give you time to design and implement a compliant solution.
