TP non-intrinsically safe telephone sets have been designed for exploitation in hard industrial conditions with no explosion hazard, including mining plants, (extensive humidity, noise, dustiness).
Thanks to the casing resistant to different atmospheric conditions and to lound calling signal, TP telephones can be used in:
  • methane free mines
  • production plants
  • shipyards
  • garages
  • warehouses
  • construction sites
  • breweries


With the standard analogue equipment of telephone exchanges of any type.

Power supply
