In today’s world, uninterrupted communication is more than just a convenience—it’s a matter of safety. Whether it’s during a fire, medical emergency, or other critical incident, first responders rely heavily on radio communication to save lives. Yet, many buildings—especially larger commercial structures—struggle with dead zones that can block emergency signals.
That’s where Bi-Directional Amplifier (BDA) systems and Public Safety Distributed Antenna Systems (DAS) come into play. These technologies are not just recommended—they’re required by fire codes and public safety regulations across the U.S.
At Allstate Power, we specialize in the design, installation, and optimization of BDA and Public Safety DAS systems, ensuring your building is safe, compliant, and future-ready.
What is a BDA System?
A BDA (Bi-Directional Amplifier) system is a signal-boosting solution designed to enhance two-way radio communication for first responders inside buildings. It captures weak emergency radio signals from the outside, amplifies them, and rebroadcasts them inside—especially in hard-to-reach areas like:
- Basements
- Stairwells
- Elevator shafts
- Parking garages
- Mechanical rooms
BDA systems work hand-in-hand with Public Safety DAS to ensure reliable communication across all areas of a facility during emergencies.
What is Public Safety DAS?
A Public Safety DAS is a specialized distributed antenna system built specifically to support public safety radio frequencies, such as:
- 700/800 MHz bands
- VHF/UHF public safety frequencies
- FirstNet Band 14 (for police, EMS, and fire departments)
Unlike commercial DAS (used to boost cellular signals for consumer use), Public Safety DAS is governed by strict regulations to ensure coverage and redundancy, including NFPA and IFC codes.
Why Are BDA and Public Safety DAS Systems Required?
Building codes are evolving to make in-building public safety coverage mandatory. According to NFPA 72 and IFC 510, newly constructed and even existing buildings must ensure that first responders have adequate two-way radio coverage throughout the premises.
If your building fails to meet these standards, the Authority Having Jurisdiction (AHJ) can deny occupancy permits or require costly retrofits.
At Allstate Power, we work closely with fire marshals and AHJs to make sure your system is designed and installed to code—the first time.
How Allstate Power Optimizes BDA & Public Safety DAS Systems
At Allstate Power, our process is comprehensive, scalable, and focused on compliance and performance. Here’s how we ensure your system works flawlessly when it matters most:
- RF Site Survey & Grid Testing
Before installation, we perform an on-site radio frequency (RF) grid test to identify coverage gaps and signal strength issues. This test maps every floor and critical area to confirm whether the building meets the required 95% (or higher) coverage mandated by local codes.
- Custom System Design
Using the data from the RF survey, we design a tailored BDA/DAS system for your specific building layout, construction materials, and use-case needs. We factor in:
- Building size and layout
- Material interference (e.g., concrete, steel)
- Existing infrastructure
- Required public safety bands
- Code-Compliant Installation
Our experienced technicians install the system according to NFPA 1221/1225, IFC 510, and local AHJ requirements, including:
- NEMA 4-rated enclosures for fire protection
- Battery backup systems for 12-24 hours of runtime
- Monitoring alarms for system faults
- Isolation from commercial DAS systems to avoid interference
- System Testing & Commissioning
Post-installation, we conduct rigorous testing to ensure:
- Coverage meets code across 95–100% of all areas
- Proper gain settings and antenna placement
- Zero interference with other systems
- Seamless communication on public safety bands
We provide full documentation and coordinate with the AHJ for inspection and sign-off.
- Ongoing Monitoring & Maintenance
Public safety DAS is not a “set it and forget it” system. Codes require annual inspections and maintenance, and Allstate Power offers long-term support, including:
- Remote monitoring
- Preventative maintenance
- Emergency repairs
- Code update compliance
