AVIXA CTS-D. Structural and Mechanical
Considerations
EMP - Energy Management Plan - answerIdentifies Energy Reduction Points
EMM - Energy Management Manager - answerA role that provides leadership and
management of the system
Wiring Diagram in terms of Energy management - answerillustrates how power to AV
components is controlled and monitored and how the energy management system is
connected to the AV system
Visual Display in terms of Energy Management - answerShows users and management
the continuous power usage of the AV system
Use of Automated Devices and Power-State Changes in terms of energy management -
answerEnsure the AV system is energy-efficient
Method for Continuous Power Measurement - answerCollect power consumption data
End-user Operation Training - answerleads to understanding, participation, and
behavior modification
Tree ideas to the energy management standard - answerData collection, automation,
education and training
How many requirements are there in the ANSI/INFOCOMM 4 :2012 Energy
management standard - answer7
How many design considerations are needed to achieve the ANSI/INFOCOMM 4 :2012
Energy management standard - answer21
Wet Systems - answerfire protection systems that use water that is always under
pressur
Dry Systems - answerdo not have water constantly present in the system and are
pressurized by the fire department in the event of a fire.
Chemical Systems - answerReplace the room air with fire inhibiting gas, such as halon,
CO2, or halocarbon agents (that contain chlorine, fluorine, or iodine either individually or
in some combination).
, Inert Gas Systems - answerDesigned to reduce the ambient oxygen concentration in a
protected space to between 10 -14%, a level that is breathable but will not support
flaming combustion. These systems use inert gases such as argon and nitrogen, either
as mixtures or alone.
What to do when firestop is in your path. - answerScrape off as little firestop as
necessary, and make sure you replace it immediately.
HVAC system basic functionality - answer1. Extract heat to and from the environment.
2. Extract heat to and from the conditioned spaces.
3. Move air throughout the conditioned spaces.
HVAC Background noise sources - answerFans
Diffusers
Ducts
Vibration - answerAnother source of noise that can be caused by HVAC systems
Should diffusers be by the presenter area? - answerYes, to keep presenter cool
Return Air Plenum - answerthe open cavity above the visible ceiling as a pathway for
breathable air. Air gets recycled via this space to the ventilation system
Styles of AV racks - answerWall mounted, Fixed, Built in, Portable, Portable Shock
Mount
Standard Equipment Rack space width - answer19 in (48 cm)
Rack unit height - answer1.75 in
Equipment Rack typical depth range - answer12 to 32+ in
Eye Height Standing for AV Rack in RU - answer35 RU (61")
Maximum patch panel height in Rack - answer31 RU (54")
Seated eye height in RU - answer24 RU (42")
ADA Unobstructed reach (media insertion or device controls) - answer15 to 48 inches
Where to place heaviest equipment in the rack - answerbottom
Signal Separation in Racks - answerGroup equipment together according to their
function to protects against crosstalk among cables through EMI
