Answers) Plus Rationales 2026 Q&A
1. Which of the following is the maximum allowable voltage for low-
voltage systems in Georgia?
a) 120V
b) 240V
c) 50V
d) 600V
Low-voltage systems in Georgia are defined as systems operating
at 50 volts or less.
2. When installing a fire alarm system, what is the minimum spacing
for smoke detectors in a standard residential room?
a) 5 feet
b) 30 feet
c) 50 feet
d) 75 feet
NFPA 72 standards require smoke detectors to be installed such
that no point in a room is more than 30 feet from a detector.
3. Which cable type is most commonly used for indoor security
camera installations?
, a) CAT3
b) RG59 coaxial
c) CAT5e/CAT6
d) Fiber optic
Ethernet cables like CAT5e or CAT6 are standard for IP security
cameras due to data transmission requirements.
4. A low-voltage contractor in Georgia must be licensed before:
a) Installing low-voltage wiring for compensation
b) Purchasing tools
c) Working on residential lighting fixtures
d) Only working under supervision
State law requires licensing for contractors performing low-voltage
installations for compensation.
5. What is the primary purpose of a surge protector in a low-voltage
system?
a) Increase signal strength
b) Reduce noise
c) Prevent voltage spikes from damaging equipment
d) Regulate temperature
Surge protectors divert excess voltage to prevent damage to
connected low-voltage equipment.
6. Which of the following is considered a low-voltage signaling
system?
a) 120V lighting
b) 240V HVAC
c) Doorbell system
, d) Water heater
Doorbells operate at low voltage, typically 12–24 volts.
7. For network cable installations, what is the maximum allowable
bend radius for CAT6 cable?
a) 1× the cable diameter
b) 5× the cable diameter
c) 4× the cable diameter
d) 10× the cable diameter
Exceeding the bend radius can damage twisted-pair cables and
degrade performance.
8. In Georgia, which document governs low-voltage installations?
a) National Electrical Code (NEC) Article 700
b) Georgia Plumbing Code
c) National Electrical Code (NEC) Article 725
d) International Residential Code
NEC Article 725 specifically covers Class 1, 2, and 3 low-voltage
circuits.
9. What is the typical voltage used for a residential doorbell
transformer?
a) 120V
b) 24V AC
c) 16V AC
d) 5V DC
Most residential doorbell transformers step down to 16 volts AC
for safe operation.
10. When terminating a CAT5e cable for Ethernet, the maximum
allowable untwisted wire length is:
