Bidirectional amplifier (BDA) systems are an essential component of public safety communications in Missouri. These systems, like a DAS (distributed antenna system), are designed to amplify and repeat radio signals, allowing emergency responders and other first responders to communicate effectively and efficiently in a variety of situations. Whether responding to a natural disaster, a traffic accident, or a public health emergency, BDA systems are an important tool for ensuring the safety and security of Missouri communities.

There are several regulations and standards that apply to BDA systems and ERRCS in Missouri. These include the National Fire Protection Association (NFPA) 72 code, which sets standards for the installation and maintenance of BDA systems in buildings and other structures. NFPA Code 1221 and 1225 may also apply. There are also regulations from the Federal Communications Commission (FCC) that apply to the use of BDA systems in the public safety spectrum. It is important for property owners and installers to be aware of these regulations and to ensure that BDA systems are installed and maintained in compliance with these standards. Your local AHJ can confirm the guidlines for BDA installation in Missouri.
