V-EVAC SYSTEM
15
VA8Z
Audio system for Public Address
and evacuation compliant with
the EN60849 and BS5839 part 8
standards for small to medium
installations
• It includes a DPS, a matrix, a digital
message player, a fully monitored
fireman microphone, amplifiers
monitoring with switch to backup
amplifier and loudspeaker line
monitoring
• It can process and control one PSS
security microphone console or up
to 8 cascaded PSM microphones
and 2 line inputs to two different
channels (music + voice)
• Each input features volume control
and equalizer
• Up to 16 digital messages can be
downloaded and recorded as Wav
files into VA8Z
• Two different messages can
be played simultaneously in
two different zones, with pre-
programmed routing via 9 alarm
inputs
• 8 output zones with a+b double line
system. A music or voice signal is
automatically or manually routed to
each zone
• Music can be switched off in each
zone separately
• It requires only two ampliers, one
for voice and one for music
• The music amplier will act as a
backup amplifier in case of the
voice amplifier failure
• In compliance with EN60849
standard, all components and
peripherals are constantly
monitored without music
interruption and all failures are
recorded
