The patented HIT-NOT® technology is based on low-frequency magnetic fields, which will reliably pass through walls and structures. The HIT-NOT® technology consists of the Magnetic Field Generator system which is placed on any type of powered equipment and the Personal Alarm Device (PAD) worn by the pedestrian. Low-frequency magnetic fields have precise markers and are much more reliable than RFID because it does not give false or nuisance alarms.
The key to HIT-NOT® effectiveness is the Personal Alarm Device (PAD). The PAD senses the magnetic field from the generator and determines the threat level: Warning or Danger. The Pedestrian wears the PAD on their shirt or vest and will receive an audible and visual warning when they enter the magnetic field around the equipment. The PAD also communicates with the generator to turn on its alarm and let the Driver know audibly and visually of the Pedestrian nearby.
The magnetic fields are elliptical in shape and are preset at the factory 30 feet in front of the generator and 30 feet behind to define the Danger Zone (60 feet total). The Warning Zone is an additional 13 feet in both directions for a total of 86 feet. When the PAD is exposed to the magnetic field, the pedestrian will receive a series of 3 beeps for the Warning Zone or a continuous alarm within the Danger Zone.
