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.

Abstract
Example safety systems for use at a loading dock are disclosed. An example safety system includes a sensor installed at the loading dock. The sensor provides a feedback signal in response to sensing the vehicle. An alarm device is mounted below a lowest elevation of the doorway. The alarm device is positioned between the first lateral plane and the second lateral plane of the doorway. An alarm signal is emitted by the alarm device in response to the feedback signal.
