Zone Display Units
Zone Display Units (ZDU's) are large LED displays, mounted in stainless steel enclosures, that allow tagging information to be displayed at specific locations if required (e.g. at Beacon location, mine entrances/exits, etc). The use of these displays streamlines personnel and vehicle access control. Typical applications are:
Maintain a Count of Personnel Past (Inbye) a Certain Point
For example a count can be kept of personnel entering a mining section and an alarm raised if the number exceeds a preset limit (e.g. the limit imposed by the availability of SCSR's, CABA Fill Points, or Refuge Bay Capacity).
Maintain a Count of Vehicles (and Vehicle Type) Past a Certain Point
Similarly to the personnel count, an alarm can be raised if a preset number is reached (e.g. when the amount of diesel horsepower exceeds the limit for the ventilation preset in that district or zone). See picture of ZDU below.
Monitor Personnel In & Out of Blasting Zones
TRACKER can streamline the tagging of personnel into safe areas as blast time approaches. For example, ZDU's can be used by people to confirm they have been correctly logged into, or out of, the blast zone. Refer to pictures above.
A range of display sizes can be used, though our two standard sizes are:
- Large ZDU is 1300mm long x 200mm high x 170mm deep (51" x 8 " x 7")
- Small ZDU is 780mm long x 150mm high x 110mm deep (31" x 6" x 4.5"), this is ZDU in the pictures above.
