Grahamstown Correctional Services




Correctional Services



As part of a major building and mechanical revamp, various South African prisons have been provided with a TOA VS-900 intercom system and public address system. The system allows prison officials to communicate with more than 120 substations positioned in cells, courtyards and passages.

In use at a number of institutions especially in the Eastern Cape, the TOA VS-900 intercom system provides reliable and intelligible voice communication for critical security applications, including corporate security, correctional institutions, educational facilities, hospital access points, and parking structures.

Ideal for applications with multiple sub stations calling in to one or more master stations, the VS-900 has a wide range of standard and software programmable features, including comprehensive Call-Forwarding to allow system operators freedom of movement and most importantly, to ensure that no calls go unanswered.
The VS-900 integrates easily with access control and video surveillance equipment via a simple RS-232 communications protocol. Other features include telephone system integration, paging and external source distribution, event logging, and recording outputs.

The VS-900 scalable architecture allows the most cost effective configuration for each application with easy expansion as the size of the facility grows. Each exchange mainframe supports up to 4 master stations and 64 sub-stations. For large systems, exchanges can be expanded or "tie-lined" to provide up to 64 master stations and 1,024 sub-stations.
The master stations can be either the TOA MS-900 or standard off-the-shelf single line telephones with support for Caller-ID signalling. Sub-stations include Economy, Indoor, Outdoor, and Panic models, each with heavy-duty plate, call switch and optional LED/relay control. Direct select interface cards provide relays, LED drivers and switch inputs for custom consoles and annunciator panels.
