AHJ ✔Correct answer-Authority Having Jurisdiction
PPE ✔Correct answer-Personal Protection Equipment
Before replacing or upgrading any system remember to ✔Correct answer-test and document the
existing system in the room before making changes. ANSI/Infocomm 10:2013
OSHA requires harnesses when working at heights more than ✔Correct answer-6 feet
Project Stakeholders ✔Correct answer-People who are most invested in the successful outcome of
the AV project
RFI ✔Correct answer-Request for information
RFC ✔Correct answer-Request for change
CO ✔Correct answer-Change order
Procurement ✔Correct answer-The process of ordering and allocating equipment, supplies, and
tools for an installation project
Information to collect on site survey ✔Correct answer-Room dimensions, layout, electrical
capacity, HVAC component locations, and any issues that may impact the AV system design and
installation tasks
Evaluating facility should be completed... ✔Correct answer-before the gear arrives
What is the primary reason an AV installer should attend weekly construction meetings? ✔Correct
answer-Identify changes that will affect the AV installation
What is considered most important during the installation of AV systems in a client-occupied space?
✔Correct answer-Avoiding disruptions to your client's business
First step when completing technical site survey ✔Correct answer-Reviewing drawing with the AV
designer
When de-installing equipment what should happen the existing connecting cables ✔Correct
answer-Removed from infrastructure
Similar to the BNC connector. This connector can be used on both multimode and single-mode fiber-
optic cable. ✔Correct answer-ST Connector
Uses conductors made from transparent glass or plastic. Used for long distance transmission of
audio, video, or data. ✔Correct answer-Fiber-Optic Cable
Conduit capacity for one cable ✔Correct answer-53% D > √d²/0.53
, Commonly used for video and radio frequency (RF), contains a single center conductor that is
surrounded by a dielectric. ✔Correct answer-Coaxial Cable
Conduit capacity for two cables ✔Correct answer-31% D > √d²+d²/0.31
Conduit capacity for three or more cables ✔Correct answer-40% D > √d²+d²+d²..../0.40
Jam ratio and number to avoid ✔Correct answer-Jam = ID/((OD1+OD2+OD3)/3) (2.8-3.2)
Single mode fiber-optic cable can run as long as ... ✔Correct answer-6,562 feet (2,000 meters)
Multimode fiber cable can run as long as ✔Correct answer-984 and 6,562 feet (300 to 2,000
meters)
Throw distance ✔Correct answer-Screen width times lens ratio (throw ratio)
Point source ✔Correct answer-Single source of audio
Distributed Source ✔Correct answer-Speakers spread out evenly
Damping factor ✔Correct answer-(DF)is defined as "the ratio of the load impedance (loudspeaker
plus wire resistance) to the amplifier internal output impedance." This basically indicates the
amplifier's ability to control overshoot of the loudspeaker, i.e., to stop the cone from moving.
AS ✔Correct answer-Above slab
NIC ✔Correct answer-Not in contract
OD ✔Correct answer-Outer diameter
ID ✔Correct answer-Inner diameter
signal-to-noise (s/n) ratio ✔Correct answer-The higher this ratio, the better the quality of the
sound or picture.
SAE Grade 5 bolt ✔Correct answer-
SAE Grade 8 bolt ✔Correct answer-
SAE Grade 2 bolt ✔Correct answer-Will show no bumps at all
ADA ✔Correct answer-The Americans with Disabilities Act of 1990 is a civil rights law that prohibits
discrimination based on disability.
Pressurized Cooling ✔Correct answer-A method of cooling in which a rack is pressurized with air,
and fans blow cooler air into the rack. Vents on the sides and top of the rack provide an escape for
the hot air.
Evacuation Cooling ✔Correct answer-Evacuation cooling creates a vacuum within the rack using
fans to draw air out of the rack, usually through the top vents.
