A micro Distributed Amplifier Unit, also called
micro-DAU (COMPACT-DAU), connects to the
analogue device loop and audio loop circuits of
Vigilon Compact VA panel. The unit can
accommodate two speaker circuits, each having up
to 5 high efficiency speakers connected in parallel.
The unit has local message store having:
¨
Audio Pack 0 - post September 2010 and
¨
Audio Pack 1 - pre September 2010
The messages and tones are for output to the
speaker circuits for announcement of emergency
and auxiliary event messages. Announcement of a
centrally stored message or live speech from the
control panel via the emergency microphone is
routed to the micro-DAUs via the audio loop for
output to their speaker circuits. The micro-DAU is
remotely powered by the control panel via a loop
circuit.
The micro-DAU is supplied in two assemblies:
¨
Backbox with front cover
