Requirements for BDA systems are enforced by local jurisdictions. It’s important to check with your county Fire Marshal to be sure of requirements per your area. Organizations like the NFPA and IFC set the standards for in-building signal coverage laws.
The general requirements for most jurisdictions are that BDA systems are required for buildings that have one floor below grade or two floors above. For most jurisdictions, BDA Systems are required in all new construction per these requirements. Many jurisdictions even necessitate retrofits of older buildings falling under these requirements.
Building owners are responsible for the cost of installing BDA systems, not the local fire department. Building owners typically choose fire protection companies to install BDA systems as part of the fire alarm bid as BDA systems fall under the category of fire alarm system.
BDA systems must be designed and installed by certified professionals. All systems must be FCC certified and must clearly display an FCC ID number and the required compliance labels. It’s the job of the AHJ to ensure that BDA systems have proper FCC certification.
