Owner standards and design manuals are examples of architectural documentation, as they provide guidelines for the physical design, layout, and aesthetics of a space. These documents influence AV design by dictating structural and design requirements.

CTS Technology Specialist ReferenceThe CTS study materials classify owner standards and design manuals as part of architectural documentation, which provides foundational design parameters for AV integration.

The primary concern for the sales representative during the site survey should be the ceiling clearance for the projector lift. Ensuring that there is sufficient space for the projector lift to operate without obstruction is crucial for proper installation and operation. Inadequate clearance can lead to difficulties in mounting and deploying the projector, potentially compromising the projection quality and system functionality. Additionally, it is important to verify that the projector can be positioned at the correct height and angle to achieve the desired image size and alignment.

According to AVIXA standards for rack design, there should be a minimum distance of 100 mm (approximately 4 inches) between AC power cables and data twisted pair cables. This spacing helps to reduce the potential for electromagnetic interference (EMI) between power and data cables, ensuring signal integrity and reducing noise.

CTS Technology Specialist ReferenceThe AVIXA standards emphasize proper cable management to minimize interference in AV installations. Maintaining a 100 mm separation aligns with best practices for reducing crosstalk and preserving data quality in networked systems.

The light output of a projection system is typically measured in lumens, which quantify the total amount of visible light emitted by the projector. Lumens measure the projector's brightness, making it a standard metric for comparing different projectors' output capacities.

Lux is used to measure illuminance or the amount of light falling on a surface.

Footcandles is another unit of illuminance, similar to lux but based on the imperial system.

Contrast ratio describes the difference in luminance between the brightest white and the darkest black a projector can produce, not the brightness itself.

CTS Technology Specialist ReferenceAccording to CTS training materials, projector brightness should be specified in lumens, which provides a clear indication of the projector's suitability for different environments and screen sizes.
