The wireless base station is a receiver that listens to all of the repeaters and sensors throughout your facility. It looks very similar to a repeater, but installs inside of the office and connects directly to the UltraConverter. The base station is powered directly from the UltraConverter. You will need an 18/4 wire to supply power and data between the base station and UltraConverter. There are four terminals on a base station: 12V, -, A and B. There are also four matching terminals on the UltraConverter which are clearly labeled. Simply match the wiring between the two devices and you are done with your base station setup. You will now see an alternating green & red LED flashing on the top of the UltraConverter, labeled, “Base Status”. If you do not see this LED, please review the troubleshooting section.
