GENERAL DESCRIPTION
UK
4.2 FUNCTIONAL SPECIFICATIONS
• Two-channel sound broadcasting system.
• Six broadcasting zones.
• Controlled double output line for each single (A and B).
• *.mp3 files read from USB flash memory as a source of background music.
• Downloading of *.WAV files from USB flash memory for emergency voice messages and chime.
• Independent 5-level volume control of the music for each zone.
• Sources for service paging announcements settable to 7 priority levels and 36 zone lists.
• System operating functions linked to different access levels, some of which protected by passwords
• Continuous control and monitoring of the integrity of the critical path (from the sources of the emergency signal to the loudspeaker lines)
without interrupting the background music.
• Monitoring of the loudspeaker lines (integrity and dispersion to earth) by means of the two-channel amplification system, even in voice
emergency conditions.
• Digital audio control (DSP).
• Easy and rapid configuration (large LCD display).
• Provisions for a web server.
• Emergency zone disabling function (Disabling).
• Do Not Disturb function for protecting the zones from accidental enabling of music or service calls.
• Acoustic signalling of failure status with automatic or manual muting.
• Manual resetting of visual failure signals and automatic resetting with storage of the last occurring failure.
• Direct procedure for starting up the system (start-up) and programming events, without using the management software.
• Possibility of adding a 250 W external amplifier to increase the output power of the system.
• Automatic management of the music amplifier as a stand-by for the operational amplifier (internal or external).
• With a second remote VAIE 2250 unit, the system can be expanded to cover up to 12 zones.
• Possibility of connecting up to 16 paging units.
• It is possible to connect up to seven remote emergency units.
