Equipment and Tool Requirements
• The DANS01 unit.
• A small flat bladed screwdriver.
• A large Phillips screwdriver (No. 2).
• A large Allen key (10 mm).
• A large nut spanner (M20).
• Suitable wire cutters and strippers.
• Suitable fixings and tools for wall mounting.
It is suggested that the fixings are pozipan head screws, with a thread length of the required fixing
length plus 9 mm, as the length of the screw inside the DANS01 back box will be 9 mm.
The screw heads must not be of a diameter greater than 7.5 mm, and their shafts need to be able to be
passed through the holes provided for them in the DANS01 back box. Therefore their shafts must not
be of a diameter greater than 4.4 mm.
• Suitable cable glands or conduit.
Gland/conduit holes provided are 20 mm diameter.
External Cabling Requirements
Signals Cable Description Suggested Type
Audio and power 2 pair, overall screened, twisted LSF sheath, foil screened.
Fire rated type: MICC, Pirelli FP200 or similar may be used.
1) Standard overall screened CAT5 can be used in non-safety applications.
2) System specifications may require fire rated cable even though the system will “fail safe” to the
maximum broadcast volume if the DANS sensor cabling fails.
3) Refer to BS7671:2008 (Requirements for Electrical Installations) or other appropriate local
standards for guidelines on maximum potential cable lengths given the actual installation
parameters.
!
!
For EMC compliance:
• Screened cables must be used where specified.
• The cable screen should be terminated to the screw terminal provided on the back box.
• All screen tails must be <3 cm.
DANS Sensor Positioning
1) The DANS sensor should be directed towards likely sources of ambient noise e.g. areas where
people congregate.
2) It should not be placed to localised sources of noise that would be unrepresentative of the area of
coverage.
3) Large areas may require multiple sensors.
Up to two DANS sensors can be used to control a single PA zone.

Recommended Installation Procedure
!
!
Please read and observe the instructions and guidelines in Section “4 Safety and Precautions” (page 11)
prior to installation. Failure to follow these instructions and guidelines may cause damage to the
equipment.
1. Ensure that the power supply to the DANS01 is disconnected at the central equipment rack.
2. Remove DANS01 front panel by unscrewing the four corner fixings (4 x Philips screws).
3. Two plastic coated steel tethers are provided to hold the front panel when the DANS01 is opened, and
to provide strain relief to the wiring connecting the PCB to the terminal block on the back box. This
allows the front panel to be opened for maintenance purposes without disconnecting the wiring. The
tethers are connected to the back box by the screws used to secure the terminal plate to the back
box. These screws should be the bottom two fixings; see Figure 1.
4. If it is desired to install the back box with the electronics assembly temporally removed for
safekeeping, first disconnect the plug-in connector from the PCB, and also disconnect both of the
tethers securing the front panel to the back box; see Figure 1.
In order to disconnect the tethers unscrew the appropriate screws. Re-fit these screws after
disconnecting the tethers.

5. Choose the required cable entry point or points, and remove the M20 blanking plug(s) at the chosen
position(s); see Figure 1.
6. If rear entry is preferred, the installer may drill holes in the rear of the back box as described below.
a. Remove the terminal plate by unscrewing the four corner fixings shown in Figure 2.

b. Drill a hole or holes in the back box for the cable gland or conduit entry. These should be in the
positions shown in Figure 3.

7. Ensure that all unused cable entry holes are fitted with blanking plugs.
!
!
Blanking plugs must be tightly fitted to preserve the unit's IP rating.
Spare blanking plugs can be ordered from ASL quoting 208112.
8. Secure the back box; see fixing hole positions in Figure 4.
The DANS01 should be directed towards likely sources of ambient noise e.g. areas where people
congregate.
It should not be placed to localised sources of noise that would be unrepresentative of the area of
coverage.

13. Reconnect any disconnected wiring and front panel tethers.
Refer to step 4and Figure 1 (page 5) for disconnected wiring and tethers.
Refer to Section “Connections” (page 9 for connection details, if required.
14. Power the DANS01 on from the central equipment rack.
The LED on the front panel illuminates to indicate that the unit is powered.
15. Secure the front panel by screwing it tight to provide an IP65 seal, but not excessively tight so that
any of the fixing threads are stressed, as this may cause them to weaken and shear.
16. The installation is complete.
17. Commission the DANS01.
Refer to Section
“Connections” (page 12).

In order to deploy DANS sensors the
system should meet the followin
g
design requirements:
1) The DANS sensors require
VAR12 or VAR20 Routers with
MKII hardware.
Refer to ASL for details of VAR
software versions supportin
g
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 also
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 be
combined with normal ANS
sensors on any zone or
g
roup 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
