Simple solutions to a complex challenge.

The latest challenge facing large buildings comes from fire departments enforcing NFPA 2010 for building radio enhancement systems. This code ensures first responder trunked radios work everywhere, and in every situation. Our fire alarm and life safety experts can help with this newly enforced requirement using our deep understanding of local, state and federal codes.

Bi-Directional Amplification (BDA) Systems

ECD Systems is a fully FCC licensed, Notifier-certified provider of first responder emergency radio enhancement systems for large buildings with trunked radio coverage problems. NFPA 72 has required BDA systems in buildings with coverage deficits since 2010, and most fire departments are now enforcing the requirements. This leaves building owners to solve all problems with spotty coverage.

ECD Advantages

The Notifier BDA System has several benefits over older distributed antenna system (DAS) solutions from radio companies who don’t understand Life Safety.

  • More cost-effective than typical DAS solutions
  • Supports all Public Safety Frequency Bands
  • UL2524 Listed as a complete system
  • NFPA 72, NFPA 1221 and IFC Compliant
  • Built-in NFPA required Fire Alarm Monitoring Module and required built-in annunciator


Unlike a typical DAS, BDA is “purpose-built” for the life safety industry to serve the latest code requirements and needs of First Responders.
