A Bi-Directional Amplifier (BDA) — also referred to as a Distributed Antenna System (DAS) — is a specialized solution that boosts radio frequency (RF) signals within buildings to ensure seamless and reliable communication for public safety personnel.
Concrete walls, steel structures, and modern energy-efficient designs often obstruct critical radio signals. BDA systems resolve this by amplifying signals and redistributing them throughout the building, ensuring that firefighters, police officers, paramedics, and other first responders can communicate clearly during emergencies.
According to the Florida Fire Prevention Code, buildings that do not meet the minimum in-building radio signal strength must install a compliant BDA system before January 1, 2025, in order to obtain or renew a certificate of occupancy or fire safety approval.
Typical buildings requiring BDA systems include:
BDA systems are essential for:
Failing to provide reliable in-building communication during an emergency can result in life-threatening consequences and legal liabilities. Installing a BDA system:
At ABAR Technology Group, we specialize in code-compliant BDA system design, installation, testing, and certification. With decades of experience in low-voltage life safety systems, we ensure your building is safe, compliant, and inspection-ready — on time and on budget.
Not all, but most buildings that fail in-building signal testing or require safety permits will need one by law.
A signal strength survey performed by a licensed provider (like Abar Technology Group) will determine if your building meets requirements.
Yes. Our team specializes in retrofitting BDA systems in existing structures without disrupting daily operations.
It varies by building size and layout. Most installations can be completed in a few days to a week after approval.
Not at all. We offer affordable annual testing and maintenance packages to keep your system compliant and operational.
