At the end of the 19th century, the company, then named "Gottfried Neumann Hochfrequenztechnik (High Frequency Technology)," quickly made a name for itself in the electroacoustics industry. In 1953, the company was renamed to "Neumann Elektronik GmbH." It produced not only the first, completely explosion-proof intercom systems, but also the cast-iron roadway emergency call columns - which were later made with fiberglass-reinforced polyester enclosures.
Various patent applications were submitted for loudspeaker systems that used central exchange systems, and the first desktop stations in a polyester enclosure with transistor amplifiers were introduced to the market.
The 1970s were distinguished by expansion - technical offices were opened, subsidiaries established. At the same time, contracts for large-scale projects were won:
Equipping 78 "S-Bahn" (rapid transit) stations in Munich with fully electronic, type EZV 68 exchange systems; equipping the Vienna subway system with centralized, microprocessor telecommunications technology; and a contract from the Deutsche Bundespost (German Federal Postal System) to install emergency call phones on German streets.
The sign of the 1980s was large-scale cooperatives: with the Deutsche Bundespost in the area of terminal units, and with the Fraunhofer Institute to develop microelectronic circuits and systems - the MDK (Multifunctional, Digital Communication System) was developed.
In the 1990s, the company intensified its presence in the international scene: the Belgium branch was opened and independent subsidiaries were established in Vienna, Austria and Russia.
It was during this time that a combined emergency call and information system for train stations and airports was developed, the first train station was equipped with 3S Centers, and the 3S System was expanded to DB PlusPoints.
To promote further expansion of the company, a new partnership structure was created for the company from Mülheim with its long-standing tradition.
The 2000s are distinguished by large-scale, international projects, such as equipping the Metro Moscow with safety and security technology, or the highly-advanced plant alarm, PA system along a 530-km pipeline in Libyan.
