ASL’s VIPA-WS is a PC-based touchscreen workstation which provides both control and monitoring of an ASL PAVA system. Simple and intuitive to use for both live and pre-recorded announcements, triggered from buttons or from a 2D graphical screen VIPA-WS, and also provides comprehensive background music control and an advanced message scheduler.
The VIPA-WS is a PC-based 23″ touchscreen GUI offering control and monitoring of an ASL Public Address or Voice Alarm system. This graphical microphone display is used alongside a separate microphone, such as the MPS IP-enabled microphone. The Press-to-Talk selection can be located either on the touchscreen or on the physical microphone itself.
In addition to using the associated microphone for live announcements, the VIPA-WS has access to pre-recorded messages held in the VIPA-WS in the PC itself. These messages can be immediately broadcast to any selection of zones, or they can be scheduled for timed broadcast. New Digital Voice Announcement (DVA) messages can be readily added by the user.
For simpler systems, the VIPA-WS can use touch-screen buttons for zone selection. The buttons will change status when selected, and ‘zone busy’ and other activity can also be seen on the screen. For a larger system, or one where a topographical representation is required, then a 2D map of the building or facility can be loaded onto the workstation and zones can be selected from the map.
Pre-recorded messages can be scheduled for broadcast on a weekly calendar, or from start to finish dates and at particular times. Any number of messages can be added to the calendar, and it is simple to set up a schedule – for example, to broadcast at 15 minute intervals between 10:00 and 17:00 on weekdays.
The VIPA-WS has comprehensive system status and logs for both faults and usage. The alarm list (faults) includes the site’s alarms priorities and descriptions. The event log includes these alarms and also a broadcast log display that includes broadcast time, broadcast sources and destinations, plus a “live or recorded” flag and the name of any message broadcast.
Connection between the VIPA-WS and the PAVA equipment is via a standard IP network – IPV4 UDP multicast with IGMPv3. Because the transmission is a multicast, it allows all of the receiving routers to listen to the same stream of data; minimizing network transmission bandwidth.
