ERCES/BDA
CHEAT SHEET DOWNLOAD

Reliable communication saves lives. When first responders enter a building, they depend on uninterrupted radio coverage to coordinate, respond, and stay safe. Bi-Directional Amplification (BDA), also known as ERCES, systems ensure those critical signals get through—even in structures where modern construction blocks them.

 

This cheat sheet breaks down what BDA systems are, why they matter, and what it takes to stay compliant—giving building owners, managers, and project teams the clarity they need to make informed decisions with confidence.
