2.11.1 Power distribution and control
Where indicated on the schematics, distributed power within equipment racks shall be controlled by means of a
network based, rack mounted, power distribution unit. Double-adaptors and single-pole switched power strips
must not be used. AV integrators must size the power strip to suit the rack and number of devices connected. A
provision for 20% expansion must also be provided. Power strips shall be protected by accessible circuit
breakers (10A on normal circuits).
Unless otherwise specified, provide switching of powered devices as follows:
a) Un-switched remote equipment (local GPO power)
! Projectors and other display devices
b) Un-switched rack equipment (power distribution unit in rack)
! Control system
! Installed PC
! Teleconference interface and Videoconference codec
! DSPs (if required for hearing augmentation).
! Any items of equipment required to ensure that the boundary microphone is active for
hearing augmentation whilst the AV system is shutdown.
! Hearing loop amplifier
c) Instant switched rack equipment. Equipment is immediately powered when AV system is activated.

Shorten power cables to an appropriate length and terminate in Australian-standard side-entry mains plug-tops
similar to Clipsal 418S or IEC style connectors.
All outlets must be clearly labeled on the control system technical page to allow for power cycling of individual
units.
