What is Bi-Directional Amplification and is it Something Your Building Needs?
First responder radio signal and communications can be significantly impacted by building construction, building size, and other factors. Because of that, it is important that emergency personnel have the ability to communicate in the event of an emergency. The good news is that there is a solution!
Bi-Directional Amplification (BDA) is an Emergency Radio Communication System that provides reliable communication radio transmissions between first responders inside a building, and emergency personnel outside the building. Below is a diagram that shows the potential dead zones that could block emergency signals from getting out.
What Does BDA Service Include?
- Site Surveys
- Maintenance & Service
- Project Management
- Post-Installation Analysis
- Testing and Certification
If a building does not meet the required minimal signal strength of -95db for both incoming and outgoing signals, the only effective solution is the installation of a signal booster (Bi-Directional Amplification).
Today’s codes, like the IBC 2015 Section 916, IFC 2015 & 2018 Section 510, NC Fire Code 2018 Section 510, NFPA 72 2010 & 2013 Editions, NFPA 1221 and UL2524, require all buildings to have approved radio coverage for emergency responders within the building based on the existing coverage levels of the public safety communication systems of the jurisdiction at the exterior of the building. Check with your local code authority to ensure your building is compliant
