Bi-Directional Amplifiers (BDA)

The IBC 2018 Code and NFPA 72, 2015 Edition requires that all new buildings (except single and dual family homes) have 95% radio coverage throughout the facility.  The Emergency Responder Radio Communication Systems (ERRCS) propagate and amplify radio signals within a building helping service personal to communicate anywhere in the facility.

Why BDA?

Emergency Responders, Firefighters, EMS, and Law Enforcement Officers rely on two-way radios for communications in every day operations. Reliable radio signal coverage is not a luxury. It is a necessity.

These systems are used to enhance in-building radio frequency in all buildings where the (RF) signal coverage is not strong enough for communications to occur between those inside and outside the facility.

How Do I Know If My Building Needs a BDA / ERRCS System?

Existing Construction – You may be unsure if your building needs a ERRCS system. If so, you can contact us at SSI, and we can come into your building and easily test the signals.

New Construction – If you’re involved in the construction plans of a new building and you do not know if your building will need a ERRCS / BDA system or if you see ERRCS / BDA in the plans but are unsure of what that entails, contact us, and we can help you through the process. 

Who Can Provide the Testing Required for a ERRCS System?

SSI has the equipment required to perform the GAT test of the radio signal strength in your current facility and on ground of a potential new facility.  The equipment works together and records the signal strength along with providing us with a report indicating the levels throughout your facility.

SSI Can Install Your System

SSI offers the components required for design and installation of the Emergency Responder Radio Communication Systems (ERRCS): signal boosters/ Bi-Directional Amplifiers (BDA), batteries and battery enclosures, donor antennas, Distributed Antenna Systems (DAS), coaxial cables, connectors and lighting arrestors, power dividers and hybrid couplers, design services and training. Picture shown is off the facility in Exton, PA where SSI installed a BDA system for the Chester County Council of the Boy Scouts of America.

Signal Boosters/Bi-Directional Amplifiers (BDA)

Our BDA’s are high gain, high power band-selective signal boosters/bi-directional amplifiers that can be designed and customized to meet all public safety frequency band ranges. It is intended to provide reliable two-way radio and FirstNet™ signal coverage inside buildings, tunnels and other structures. The band selective design delivers a reliable performance in even the most challenging RF environments.

State of the art design delivers high reliability and excellent performance in a small, lightweight, and economical package. Our BDA’s have been tested and evaluated in accordance with UL2524 1st Edition requirements for In-building 2-Way Emergency Radio Communication Enhancement Systems, NFPA and IBC/IFC standards compliance—making it the best choice for public safety and other mission critical applications.


FCC License

SSI has 5 staff members with the GROL (General Radio Telephone Operation License) that is required by the FCC to perform a signal strength test. These tests of your facility will determine if your building requires additional coverage. Our system installations comply to all NFPA / IBC / IFC and local municipality standards, to be the best choice for public safety and other mission-critical applications.
