Critical communication.
When it matters most.
Bi-Directional Amplifier (BDA) and Emergency Responder Radio Communication Systems (ERRCS) designed to support reliable first responder radio coverage inside commercial facilities.
Helping first responders stay connected inside buildings.
Concrete, steel, low-emissivity glass, and other building materials can reduce public safety radio signal coverage inside commercial structures.
Where required, BDA and ERRCS solutions help improve in-building radio communications so firefighters and emergency personnel can communicate more effectively during an incident.
DeGraaf Systems supports commercial BDA projects through facility-specific planning, installation, system integration, and coordination with project stakeholders.
Coverage. Coordination. Compliance.
Every building has different radio coverage conditions and applicable requirements.
Integrated solutions for public safety radio coverage.
From initial evaluation to system commissioning, our approach considers the building, the communication requirements, and the applicable approval process.
Coverage Assessment
Reviewing facility conditions and available radio coverage information to help identify project requirements and potential coverage challenges.
System Design Coordination
Planning around the facility layout, construction materials, public safety frequencies, and requirements established for the project.
BDA Equipment Installation
Installation and integration of amplifiers, distributed antennas, coaxial cabling, and supporting infrastructure.
Testing & Commissioning
Supporting performance verification, system commissioning, and required testing activities.
AHJ & Inspection Support
Coordinating project documentation and inspection activities with the appropriate authorities and project stakeholders.
Maintenance & Support
Helping facilities address system maintenance, service needs, and changes that may affect emergency radio coverage.
Designed around the requirements of the facility.
In-building emergency responder radio coverage requirements vary based on the adopted codes, jurisdiction, building conditions, and applicable public safety radio network.
A BDA or ERRCS solution may be required when a building does not meet applicable emergency responder radio coverage criteria. The authority having jurisdiction (AHJ) determines the specific requirements and approval process.
Applicable Codes & Standards
Project requirements may reference adopted fire codes, NFPA standards, and jurisdiction-specific criteria.
Public Safety Radio Compatibility
System requirements depend on the frequencies, signal conditions, and operational needs of the local emergency responder network.
Inspection & Acceptance
Testing, documentation, and system acceptance requirements are coordinated according to the applicable project criteria.
Ongoing System Performance
Inspection, testing, and maintenance requirements should be considered throughout the system’s service life.
Supporting communication in complex facilities.
Large buildings, multistory structures, and facilities with signal-blocking construction can present challenges for emergency responder radio communications.
Warehouses & Manufacturing
Large footprints, high ceilings, and industrial construction can create challenging radio coverage conditions.
Healthcare & Education
Complex building layouts and critical operations make emergency communications an important planning consideration.
Offices, Retail & Mixed-Use
Multistory buildings, parking areas, and interior spaces may require additional radio coverage evaluation.
From evaluation to system performance.
Evaluate & Coordinate
Review facility conditions, identify project requirements, and coordinate with the relevant project and approval teams.
Install & Integrate
Implement the specified equipment, cabling, antennas, and supporting system infrastructure.
Test & Support
Support system verification, commissioning, inspection coordination, and ongoing service requirements.
