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.
