Mr Bernard Price, in 1925, the then chief engineer of the Victoria Falls Power Company stated that electric energy is the "life-blood of the mining industry." The Rosherville Power Station is an example of this statement.

It was built in 1911 by the Rand Mines Power Supply Company (RMPS), which was a subsidiary of the Victoria Falls and Transvaal Power Company Limited (VFP), to supply the gold mines of the Witwatersrand with electricity and compressed air. This was at a time when South AfricaÆs mining industry was increasing in size rapidly and the only way for it to maintain that growth was for it to use electricity. Both VFP and RMPS would supply power under separate licences granted by the government in terms of the Transvaal Power Act of 1910.
In a life span of fifty-five years, from 1911 to 1966, it did not only produce electricity and compressed air for the mines, but also became a thriving and closely knit community.

The TOA VX-2000 Integrated Voice Evacuation System (covered by a 5 Year Warranty), originally built to comply with EN60849:2005 (adopted by SA as SANS60849) is ideal for this type of application where there are multiple zones and each floor is to be treated as an independent zone which is capable of having its own dedicated microphone for the Fire Marshall controlling that floor.
The entire system is self-monitored every 100 seconds with fault indications registering on the rack equipment as well as the control microphones. Logs are automatically generated (announcements, system faults, inputs, automatic messages and alarm tones, faulty lines, etc).
It is also possible to utilize the system for BGM (Background Music) as each zone is able to have its own music source and volume levels or the same source can be routed to specific zones, a group of zones or all zones). White noise too, can be integrated with the system.
