TPN telephone

Industrial Telephones TPN

Application
TPN 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, TPN telephones can be utilised in:
  • shipyards
  • garages
  • industrial plants
  • building sites
  • warehouses
  • breweries

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

Power supply
From subscribers' equipment of analogue telephone exchanges.
