In 1946 a Norwegian, Otto S. Knudsen, began producing life saving marine radios in Trondheim, Norway, leading to the production of radio sets, car radios and eventually intercom systems. This was the start of a company gaining international significance for its groundbreaking innovation -- STENTOFON intercom.
Production of intercom systems began as early as 1946 but really increased in 1960 with the launch of the STENTOFON ST30 intercom system. Export contacts were established with a number of countries and offices opened abroad in Denmark, Sweden, Germany, France, USA, UK, China and Australia.
The first intercom models (Pamex) were released in the early 1970’s. Intercom development went into overdrive in the early 80’s with the introduction of microprocessor controlled systems. The primary product being manufactured at this time was the Pamex MPC and TouchLine systems. TouchLine was eventually phased out by the digital AlphaCom system. Today, STENTOFON's AlphaCom VoIP system is used in a wide range of applications worldwide.
