In order to deploy DANS sensors the
system should meet the following
design requirements:
1)
The DANS
sensors require
VAR12 or VAR20 Routers with
MKII hardware.
Refer to ASL for details of VAR
software versions supporting
the DANS System.
2)
Each DANS sensor requires one
microphone input on an Expand
Unit:
•
Inputs 5 to 12 on VAR12
•
Inputs 5 to 20 on VAR20
3)
The DANS sensor must be
connected to a microphone
input located on the same
Expand Unit as the output(s)
that it controls.
4)
Each
DANS
sensor
requires an output on that
Expand Unit to be unused.
5)
Up to three DANS sensors can
be connected to each Expand
Unit.
6)
The Expand Units with DANS
sensor(s) do not support DVAs.
7)
DANS
sensors
cannot
combined with normal ANS
sensors on any zone or group of
zones.
8)
Up to two DANS sensors can be
used to control the same
output(s).
9)
DANS sensors can control more
than one output (e.g. if a zone is
separated into separate sub-
zones for other reasons).
10) Ideally if there are two DANS
sensors then they should be
connected to:
•
Inputs 10 and 11 on VAR12
or VAR20, or
•
Inputs 18 and 19 on VAR20
also
be
