All buildings with insufficient in-building radio frequency coverage in critical areas of the building must install a ERCES/BDA before JANUARY 1ST 2022. This provides only a short window to install the ERCES/BDA—including retrofitting into existing buildings—into every building with poor in-building radio coverage. All newly installed BDA systems require licensed certified company (CSS) to annually test the system for proper operation per NFPA 72: 9.22.1 (verify code!)
