What is the primary reason for documenting ceiling height during an AV site survey?
Answer: To determine projector throw distance and display mounting options
Ceiling height directly governs projector placement, throw distance, and feasible mounting heights for displays and screens.
You discover during a survey that the planned AV room has only two 20-amp circuits for a large system. What is the correct course of action?
Answer: Document the deficiency and coordinate with the electrical contractor for additional circuits
Power deficiencies must be documented and resolved through the electrical contractor before AV installation begins.
Which environmental factor most significantly increases projector lumen requirements in a space?
Answer: High ambient light from windows and overhead fixtures
Ambient light competes directly with the projected image, requiring higher lumen output to maintain adequate contrast ratio.
What is the primary HVAC concern when selecting a location for AV equipment racks during a site survey?
Answer: Ensuring adequate cooling airflow while protecting equipment from dusty air return paths
Equipment racks generate significant heat and require clean, cool airflow while being positioned away from dusty air return paths.
During a survey, you find the facility operates on 208V single-phase power. What AV planning step is required?
Answer: Verify AV equipment voltage compatibility and plan for step-down transformers if needed
Many AV devices are rated for 120V, so a 208V supply requires compatibility verification and potential transformer use.
Why is documenting VLAN configuration important during an AV site survey?
Answer: To properly segment AV control traffic and avoid conflicts with other network services
AV control systems and networked AV devices often require dedicated VLANs to ensure reliable operation and avoid IP address conflicts.
Which tool is most appropriate for verifying that a concrete floor is level before installing equipment racks?
Answer: A spirit level or digital inclinometer
A spirit level or digital inclinometer accurately measures floor levelness, which is critical for stable and plumb rack installation.
