Why ERCES & BDA Systems Are Required by Law
Modern building codes — including IFC Section 510, NFPA 1221, and local AHJ requirements — mandate that all new construction and major renovations maintain reliable two-way radio communication for first responders throughout the building. Without a compliant ERCES (Enhanced Radio Coverage for Emergency Responders System) or BDA (Bi-Directional Amplifier) system, a building cannot receive a Certificate of Occupancy.
Sentinel Public Safety Systems supplies the signal distribution infrastructure that licensed contractors and integrators need to design, install, and commission code-compliant in-building public safety systems — from donor antennas and power tappers to filters, connectors, and test equipment.
