The VoCALL Emergency Voice Communications System (EVCS) is designed to fully comply with BS5839-Part 9:2003 for use as a Fire Telephone system, Disabled Refuge Call system or as a combined system when both Fire Telephones and Disabled Refuge Points are required. An EVCS is a fixed, secure, bi-directional, full duplex voice communication system to assist fire fighters in an emergency in high rise buildings or large sites where Radio communication may not work, and covers the operation of both fire telephones and disabled refuge systems. Where both systems are fitted to a building BS5839 Part 9 specifies these should form a single system. A VoCALL EVCS comprises of three functional blocks, the master handset (VCM) the eight line Exchanges (VCX-8) and outstations, (type A, type B or Jack points), with the quantities of these basic units being adjusted to suit the application.
