When a person receives an alarm by Hit-Not® , they know that they are personally being threatened by a vehicle.  If only a potential danger, an intermittent warning alarm is given.  If a threat is dangerously close, a more intense, continual, danger alarm is given.

If a pedestrian is in the Warning zone of one vehicle, but is also in the Danger zone of another vehicle, the pedestrian will be given the Danger alarm rather than the Warning alarm.

Audible alarm devices are positioned near the ear of the worker and visual alarm devices are near the eye of the worker so that they are more certain to be heard and seen and so that they will not distract or be a nuisance to other persons in the area.

When wearing hard hats, the audible alarm is attached to the brim so that it is within 6" of the ear and the visual alarm is within the peripheral vision.  When the PAD is attached to a safety vest, the alarms are within a foot of eyes and ears.

Provisions for multiple persons, multiple machines or hazards, silent zones and other considerations related to personal alarms are explained elsewhere.

If the Proximity module is configured with Collision Avoidance, it will be transmitted to a server for future evaluation.

PADs automatically transmit safety data when the pedestrian enters or leaves a zone so that it can be received, evaluated real-time or stored if other required Hit-Not®  is being utilized.

A Zone monitor will be available August 1, 2013 that can collect the transmitted data for use or storage.
