At Kazungula Bridge, a bridge that was built by the governments of Zambia and Botswana above the Zambezi River, the government of Botswana also constructed a “One Stop Border Post (OSBP)” which enables travelers and goods to stop only once when crossing the border between the two countries, as part of border formalities.

Each building was designated with its own paging zone which is selected via the microphone station, so that announcements can be made to, and heard from the speakers in selected zones only, or as a group when required. The evacuation messages can also be broadcasted to specific speaker zones, as and when required.

The VX-3000 system proved to be an excellent solution for a centralized system with long distances between remote buildings.

Johannesburg City Theatres decided to upgrade their Voice Alarm and Audio Systems at three different locations.



The theatres, boardrooms, and public and event spaces were equipped with new Integrated Voice Alarm, Intercom and Paging Systems as well as IP Intercom Systems
