We are pleased to announce that TOA's VX-3000 Series got certified with EN 50121-4 (IEC62236-4), the electromagnetic standard which applies to a signaling and telecommunication apparatus installed in railway environments. Those systems can now be utilized in railway applications where EN 50121-4 is required. EN 50121-4 specifies limits for emission and immunity and provides performance criteria for signalling and telecommunications apparatus which may interfere with other apparatus in the railway environment, or increase the total emissions for the railway environment beyond the limits defined in the appropriate standard and so risk causing electromagnetic interference to apparatus outside the railway system.
VX-3000 : Series Public Address and Voice Evacuation System The VX-3000 is a highly integrated scalable Public Address and Voice Evacuation System that is fully EN 54-certified. Due to its network-based architecture, it can be easily scaled to up to a maximum of 2,560 speaker lines and 1,280 remote microphones.
