Opening and Closing Control
Opening priority (falling barrier arm will rise if there is a rise signal) and closing priority (rising
barrier arm will fall if there is a fall signal) functions are available. It can be controlled by digital
on-off input, remote control, and RS-485 serial commands.
Automatic Rise when the Barrier Arm Meets Obstacle (Pressure Wave
Anti-smashing)
Falling barrier arm will immediately rise to the vertical state when it meets obstacles, to protect
vehicles or pedestrians. Sensitivity is adjustable.
