Application

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

Cooperation

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

Power supply

From subscribers’ equipment of analogue telephone exchanges.
