2.12.10 Labeling scheme
The AV integrator shall present a cable labeling scheme for the facility and submit for approval by the
Principal., Submit details of proposed cable, connection plate and patch bay labeling scheme to Principal prior
to manufacture / procurement. No variation costs shall be accepted for re-labeling of unapproved or rejected
labeling.
Labeling scheme shall include:
a) Robust, repeatable labeling
b) Cable labels are self-laminating vinyl similar to Brady WML-305-292-2S with laser or other indelible
machine printed text. Labels shall be protected from physical damage and be clearly legible.
c) Connector and patch plates shall be directly engraved with appropriate legends
d) AV Integrator’s name or logo may be included on cable labels only where it does not impact on the
legibility of the specified information. AV Integrator’s name or logo is not to appear on any plates.
e) Logical sequential system for ALL cables
f) Label ALL equipment and cables to facilitate simplified operation and maintenance.
g) Label both ends of all cables with an approved labeling system. Labels shall be placed to ensure
ease of identification.
h) Submit a sequential cable numbering system for approval by the Principal.
i) Labels shall include cable number, signal source and destination information
j) A copy of the as-built cable schedule shall be included in the operation manual.
k) Shielded CATx cables used for AV purposes (e.g. video/USB extenders) must be clearly labeled
as AV cables at both ends to avoid being connected to incorrect devices.
Pen or permanent ink marked labels will not be accepted.
2.13 Image projection/display
2.13.1 Luminance
Screen luminance at all points on the screen shall be no less than 50 nits. Luminance at the edges of the
screen (5% in from each edge) should be not less than 75% and not more than 90% of that at the center. The
distribution of screen luminance should be symmetrical about the geometric center of the screen.
2.13.2 Projected Contrast
When the room lighting is set for projection viewing, the ratio between ambient black (i.e.: light incident on the
screen from ambient sources and room lighting) and projected white shall be a minimum of 7:1. Contrast ratios
greater than 10:1 are preferred.
2.13.3 Size and position
Unless otherwise specified, all systems in this facility are specified for the projection of data.
All images shall meet the following criteria. Where all criteria cannot be simultaneously met due to the layout of
seating, they shall be applied in order:
