Evacuation from road and rail tunnels is be a complex task. When in a tunnel, the general public need clear instruction on what actions to take in a difficult acoustic space often with high noise levels.
Our VIPEDIA-12 router can provide up to 60 seconds of delay for time alignment purposes. Routers can be located up to 2000m (multi-mode) or 10000m (single mode) apart using fibre optic connectivity. Because the V2000 includes its own power supply and charger, the distributed racks can be fully EN54-16 compliant and still only take up less than 12U of space in a rack, even with 24hr battery supply. For monitoring and control, ASL’s VIPA-WS stores Digital Voice Announcements (DVA) ready for broadcast, and then constantly monitors the status of every ASL device and loudspeaker in the tunnel – an essential feature for a system that has extended periods of standby time.
The ASL solution can push system status information to a SCADA system, or alternatively, for total monitoring, ASL’s iVENCS Control System can be used to fully manage all telecom subsystems on one or multiple 3D GUI workstations. In addition to offering touchscreen control, the EAP01 IP65-rated microphone can be located at tunnel entrances for easy access when needed. Meanwhile we can tailor our solution to fit all types of different loudspeaker brands and models, whilst the VIPEDIA-12 offers equalization on every output that can match the particular loudspeaker being installed.
With sophisticated routing, fibre optic connectivity and sufficient battery backup, ASL’s systems ensure PA and VA intelligibility and availability around the clock – ready to be relied upon for when it’s required.
