The BARTEC VODEC VX/AT is designed to
provide access priority and zoned area switching
of electronically generated alarms and live voice
program inputs as a central component of a high
integrity Public Address and Alarm (PAGA)
broadcast system.
The VX/AT unit comprises of a low profile space
saving 1 unit high 19 inch enclosure 160 mm
(6,5 inch) minimal depth enclosure.
As standard the VX/AT switch accepts connection
of up to four microphone access control
positions, expandable to client specification.
The unit generates a selection of secure alarm
cadences and provides interface to other
telecommunication packages:

• Entertainment distribution system Muting in emergency
• Telephone system, Telephone subscribers can store and replay messages over the PAGA loudspeakers (BARTEC VODEC RP8 required)
• Fire and Gas Detection system, Automatic initiation of PAGA alarm tones
• Supervisory system, PAGA trouble warnings

A single BARTEC VODEC VX/AT switch can automatically supervise

• up to 64 or 512 power amplifier modules VA300+
• up to 32 microphone access panels
• battery charger
• flashing beacons

The unit incorporates comprehensive signal processing to ensure highest speech intelligibility.
The LED diagnostic display and test tone/supervisory reset control, enables the engineer to issue test tick tone on a zone by zone basis. Supervisory routines automatically check critical path performance from operator microphone through to loudspeaker network and end of line devices. The complete unit is connected to the host amplification equipment by ?quick release? plugs and sockets. This allows rapid service replacement on a plug and play basis. VX/AT switch generates both IMO and PFEER/NORSOK alarm tone menus with alternative alarm tone cadences/frequencies readily programmed on request.

Alarm tones are fully monitored and the package is equipped as standard for high criticality duplicated A/B system operation. The alarm tone package is fully synchronised when used in A/B applications. Service is maintained in the event of failure of an alarm tone generator in either A/B system. Priority access ensures that routine broadcasts are automatically over-ridden by critical input requests.
