The PBE Group received approval from the Mine Safety and Health Administration (MSHA) for its Model BDA-4 Bidirectional Line Amplifier. The BDA-4 provides local and optional remote diagnostics to indicate the current state of the amplifier for ease of maintenance of a site’s leaky feeder system. It supports voice and high-speed data transmission, incorporates bidirectional amplifiers, has wired and wireless interconnectivity and a third auxiliary band. The BDA-4 amplifier’s third amplified band can be used for paging, radio or evacuation systems.
The BDA-4 amplifier also allows the PBE personnel and vehicle tracking system to become a hybrid solution by offering the underground tag reader enclosed in the amplifier. This hybrid solution will further reduce the cost of adding key safety products such as underground tracking by eliminating the need for additional power and cabling requirements.
