Found in many configurations throughout the world, drop-arm signals not
only provide audio and visual warnings (bells and lights), but lower a physical barrier to prevent pedestrians or vehicles
from entering dangerous areas. When activated, our unit starts to flash and ring, and after 5 seconds, lowers the arm. The
RMI unit is operated by a 12 VDC linear actuator. The standard model has 2 flashing lights mounted on the pole,
additional lights on the arm, and an automatic gong. Options include additional flashing lights, cast base boxes, battery
power supplies, and solar power options. The exclusive RMI control system is microprocessor controlled for the most demanding operating options. Various track sensor options are available from block shorting to inductive loop sensing.
