1. A safety system for a loading dock that includes a vehicle restraint adapted to engage a vehicle parked at the loading dock, the vehicle restraint having an electrical component, the safety system comprising:

  • a first sensor installable at the loading dock to sense the vehicle approaching the loading dock and to provide a feedback signal in response to sensing the vehicle;

    an alarm device to be electrically wired to the electrical component of the vehicle restraint, the alarm device being configured to receive the feedback signal from the first sensor;

    an alarm signal emitted by the alarm device in response to the feedback signal to warn a pedestrian in a path of the approaching vehicle detected by the first sensor;

    a second sensor installable at the loading dock, the second sensor to sense and generate a feedback signal representative of the vehicle restraint being in an operative configuration to restrict movement of the vehicle relative to the loading dock and a stored configuration to allow movement of the vehicle relative to the loading dock; and

    a signal device installable at the loading dock and being positioned at a remote location from the alarm device, the signal device to receive the feedback signal from the second sensor and to generate an output visible to a driver of the vehicle corresponding to a status of the vehicle restraint sensed by the second sensor.
