VA4Z M
AUDIO SYSTEMS
V-EVAC SYSTEM
16
Audio system for Public Address
and evacuation compliant with
the EN60849 standard for small to
medium installations
• Matrix composed of 4 audio
inputs, 1 microphone input for
emergency messages, 4 outputs
for 4 independent zones
• This system includes the
cascading of VA4ZM master
module and one or several
VA4ZS slave modules
• It extends the capacity of the
whole system to 288 inputs for
VA4Z XM
Audio system for Public Address
• It has the same features as
VA4ZM and, in addition, it
features the automatic gain
control: the sensing microphone
(PABFMP) can be connected to
one of the audio inputs
• It will allow VA4Z to carry out an
intelligent measure of the noise
level, adapting the gain of the
corresponding zones
