DAS (Distributed Antenna System)

Almost every major city in the US has mandated Emergency Responder Radio Communications System (ERRCS), also known as First Responder DAS (Distributed Antenna System).

VFS Fire & Security Services is a FCC license hold contractor, required for the installation. Our experts will design, furnish and install the specific requirements needed for your building. VFS will submit design‐ build drawings, test and commission the system with the local Authority Having Jurisdiction, and register your Booster Amplifier with the FCC.
