More than 100 years of evolving critical communication

  • The next step to strengthen our market position came in 2021 as Zenitel joined forces with ASL (Application Solutions Limited). With more than 30 years of experience, ASL has a strong offering of Public Address, General Alarm and Voice Alarm Solutions (PAGA/PAVA),  as well as Control Management products. With ASL in the Zenitel group, it enables Zenitel to further strengthen its market position in intelligent critical communication solutions.

    The combination of both product ranges is a key benefit to deliver higher added value solutions to our end customers. The solutions of ASL are strongly appreciated by end customers in transportation (rail, airports and tunnels), education, maritime, energy, building security, theme parks, stadiums, nuclear power plants, industry and retail.

  • The Norway developed products of Phontech are specialized in Intercom and Public Address & General Alarm solutions for the global Maritime and Energy markets.  In 2018, Phontech entered the Zenitel group. It resulted in strengthening the Zenitel position in multiple markets by combining Public Address and Intercom technologies. This strategic acquisition strengthened Zenitel’s position as a worldwide market leader for intelligent critical communication solutions in the Maritime and Energy industries. The Phontech team joined the Zenitel Horten offices.

  • The merger of the two brands was a strategic goal in keeping with Zenitel’s corporative objectives as all products are designed, developed and manufactured under the Zenitel Group.

    Vingtor-Stentofon, has a long, rich history supplying products that are known for their robust features and an open architecture that allows for easy integration with other 3rd party devices including access control, CCTV, alarm systems and IPBX. We strive to be a technology leader by providing high-end features and solutions such as active noise cancellation, supervision, audio analytics, and an open architecture structure for interoperability.

  • In May 2000, a decision was taken on a merger between Stento ASA and the reorganized SAIT-RadioHolland. In 2001, Zenitel celebrated its 100th anniversary and changed its corporate identity and name to Zenitel. Early 2009, in order to guarantee the profitability of the Zenitel Group, especially given the global financial and economic crisis, it was decided to focus all commercial efforts on the continuing development of Secure Communication Systems. On September 29, 2015 Zenitel celebrated its 50th anniversary as a registered company on the Euronext Exchange.

    All through these years, one aspect hasn’t changed: since 1901, Zenitel has been providing the means for people to hear and be heard. Zenitel has no intention of changing its course; indeed, the business of security and communication is due to become one of the most relevant businesses in the near future. That is because it relates to the safety of people.

  • Stentofon began in 1946 as Stentor Radiofabrikk, specializing in ship and fishing boat radios. Later, Stentor sold STENTOFON intercom systems. Stentofon AS merged with RingCom AS in 1997, which was formed by Ring-Master and Noracom. Gothenburg's Ring Marine AB joined. Ericsson Marine and Teleste Marine became part of Ring Marine AB. Stento ASA was formed by Stentofon and RingCom.

    Stento acquired VINGTOR Marine in 1988 after eight years of working with Vingmed AS to adapt PAMEX and other onshore intercom systems for onboard communications. Croatia, Germany, Singapore, and China became subsidiaries. Vingtor bought Steenhans and Phonico in 1998.

    Ring-Master and Noracom both did business with Motorola, and Stento became Motorola's Nordic distributor. Stento quickly grew by acquiring Philips Intercom and Nursecall.

  • Following World War II, the company (then named S.A.I.T. Electronics – Société Anonyme Internationale de Télégraphie), entered into various collaboration agreements with other companies, including Radio Holland N.V. and Norsk Marconikompagnie A/S.

    In 1992, the successful partnership with Radio Holland led to a takeover and SAIT Electronics began trading under the name SAIT-RadioHolland.

  • The history of Zenitel dates back to 1901, when a group of Belgian entrepreneurs founded C.T.S.F. – Compagnie Générale de Télégraphie sans Fil.

    None less than King Leopold II and Guglielmo Marconi, the inventor of the wireless telegraph, supported them.
