DANS01 – Installation Guide
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
Audio and power 2 pair, overall screened, twisted
Suggested Type
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
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
In order to disconnect the tethers unscrew the appropriate screws. Re-fit these screws after disconnecting the tethers.

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
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.

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.

TO ROUTER
AND RACK
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 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 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 subzones 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
