VA4Z S VA4Z SU
Slave module 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.
Optional switching module
• Maintains the emergency
microphone facility to the VA4Z
• In case of failure of one or more
master or slave units, it will
automatically connect one PSS
microphone station directly to
amplifier input, allowing users to
make an all-call announcement
• For each zone it allows a+b wiring
on same amplifier: when two
loudspeaker lines are used in
a zone, they can be connected
to the same amplifier and this
module will ensure the separate
line surveillance, in compliance
with the EN60849 and BS5839 part
8 standards
Slave module for Public Address
audio system
• It has the same features as
VA4ZS and, in addition, it
features 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
