WHAT MAKES HIT-NOT® ROBUST?

Nuisance Alarms and False Alarms REDUCED

HIT-NOT® warns each individual only when that individual is dangerously close to a vehicle/mobile machine. HIT-NOT® also warns individual operators only when a pedestrian with a PAD is close enough to his/her vehicle/ mobile machine to be in danger. Precise safety zones are provided all around the trucks, being longer in the front and rear than on the sides. The pedestrian and the operator will respond to warnings given to them individually when they, individually, are in jeopardy or when they are jeopardizing the safety of a pedestrian.

No LIMIT on PADs or MFGs in a Facility

  • Pedestrian Alerts have priority over Collision Avoidance. 
  • Any number of PADs can be used within a facility with no conflict. Each pedestrian will be individually warned about any threat to themselves, as if no other PADs were in the facility. 
  • Multiple vehicles can be operated within a work area without conflict.  However, if more than five fork trucks are within 50 feet of a PAD, warnings on the fork truck operators may begin to delay.
  • The number of PADs in a Safety zone has no effect on the size and shape of the zone and has no effect on the reaction time of the system.

Fields Stable under most ALL conditions

  • There are no multi-path errors due to reflections, such as is experienced with RFID devices. 
  • Parasitic coupling onto pipes, wires, and metal objects, commonly experienced with higher operating frequencies is avoided.
  • Metal objects within the safety zones will not significantly affect the precision of the magnetic field.

FAILSAFE Design Practices followed

  • Any hardware can fail or can be damaged in some way, even after all possible steps have been taken to avoid failure. It is impossible to guarantee that systems can never fail, but Engineers designing HIT-NOT® have taken measures making it very unlikely that the hardware would be used in a failed condition.
  • Before a decision is made that a PAD or CAM is entering or exiting a safety zone, it will be confirmed multiple times.
  • MFGs have an independent relay that turns on the Alarms if the electronics loses internal power or otherwise ceases to work properly.
  • PADs provide a positive indication if their processor determines that they are working properly.
  •  If a PAD battery charge is low, and that PAD enters the warning zone or danger zone of a MFG or a MAC, the MFG or MAC alarms will be set off until the PAD is removed from their zones.
  • HIT-NOT® recommends and offers additional products to quickly test functionality of its devices on a daily basis.

HIT-NOT® magnetic field technology Proven, Reliable since 2005

  • 100% of all Personal Alarm Devices (PADs) and Magnetic Field Generators (MFGs) are functionally tested before shipment, to confirm that there are no defective parts and that the devices have been assembled properly. But, even then, they can be damaged during assembly or during use.
  • The factory-designed mounting kits normally ensure that the MFGs are adequately spaced from metal surfaces to retain their factory distance settings. Installers should verify proper operation at the time of installation.
  • PADs use replaceable, rechargeable Li-ion batteries that will typically last for more than 16 hours before recharging; but we recommend fully charging them after each shift and replacing yearly. 
  • PADs should always be kept and used in HIT-NOT® Vests or Pouches.
