Control Boxes

UMD-SRB02 Control Box

The UMD-SRB02 Control Box is used in conjuncture with the bi-directional VG Rope Brake to protect against overspeeding and unintended movement.

This unit will connect directly to the main lift control panel, where it can receive power and signals to tell if the lift doors are open, or that the lift overspeed governor is okay. It also sends signals to the lift to say stop on the next floor if there is a problem, or emergency stop.

The UMD-SRB02 has an internal battery back-up system for the event of power loss, and switches seamlessly from mains power to battery and back again without the need for manual intervention to reset the brakes.

RB2a Control Box

The RB2a Control Box is used in conjuncture with a VG Rope Brake to protect against overspeeding in the upward direction.

This control unit incorporates a battery back-up circuit to prevent spurious operation should the power be disconnected for whatever reason. This will keep the VG Rope Brake disengaged and fully operational for a minimum of 3 hours.
