1Which Alaska state agency administers the Low Voltage Alarm or Signaling Device Contractor license?

A.Alaska Department of Labor

B.Alaska Department of Community & Economic Development

C.Alaska Department of Transportation

D.Alaska Building Authority

Explanation: The Alaska Department of Community & Economic Development (DCCED) administers the Low Voltage Alarm or Signaling Device Contractor license through the Division of Corporations, Business & Professional Licensing (CBPL). This agency oversees all professional licensing in Alaska.

2What is the official license classification for low voltage alarm work in Alaska?

A.Low Voltage Electrician

B.Low Voltage Alarm or Signaling Device Contractor

C.Limited Energy Systems Specialist

D.C-7 Low Voltage Contractor

Explanation: Alaska uses the designation 'Low Voltage Alarm or Signaling Device Contractor' for professionals who install, maintain, and repair low voltage alarm and signaling systems. This classification is specific to Alaska's licensing structure under DCCED.

3Under NEC Article 725, which class of remote-control circuits operates at power levels that do not exceed the limits specified in NEC 725.121?

A.Class 1

B.Class 2

C.Class 3

D.Class 4

Explanation: Class 2 circuits are limited to specific power levels defined in NEC 725.121, typically not exceeding 100 VA. These low-power circuits are commonly used in thermostats, doorbells, and security sensors. Class 2 wiring has reduced installation requirements due to the inherent safety of the low power levels.

4What NEC article covers the installation of fire alarm systems?

A.Article 725

B.Article 760

C.Article 770

D.Article 800

Explanation: NEC Article 760 specifically covers the installation of wiring and equipment for fire alarm systems, including power-limited and non-power-limited fire alarm circuits. Article 725 covers remote-control, signaling, and power-limited circuits in general, while Articles 770 and 800 cover optical fiber and communications circuits respectively.

5What is the maximum voltage for a Class 2 circuit power source?

A.30 volts

B.60 volts

C.100 volts

D.150 volts

Explanation: Class 2 circuit power sources are limited to a maximum of 100 volts as specified in NEC Article 725. However, the current is also limited, keeping the total power within safe levels. Most practical Class 2 circuits operate well below this maximum, typically at 12V or 24V DC.

6Which type of cable is required for plenum-rated installations?

A.CM cable

B.CMR cable

C.CMP cable

D.CMX cable

Explanation: CMP (Communications Plenum) cable is required for installations in plenum spaces, which are areas used for air circulation in HVAC systems. CMP cables have fire-resistant jackets that produce minimal smoke and toxic fumes when exposed to fire. Using non-plenum cable in these spaces is a code violation.

7In a fire alarm system, what is the primary purpose of an end-of-line (EOL) resistor?

A.To boost signal strength

B.To provide supervision of the circuit for opens and grounds

C.To reduce voltage to the last device

D.To filter electrical noise

Explanation: An end-of-line (EOL) resistor is placed at the last device on a fire alarm initiating or notification circuit to provide supervision. The fire alarm control panel monitors the circuit current flowing through the EOL resistor. If the circuit opens or shorts, the current changes and the panel detects a trouble condition.

8What is the maximum pulling tension typically recommended for Cat 6 UTP cable?

A.10 lbs

B.15 lbs

C.25 lbs

D.50 lbs

Explanation: The maximum pulling tension for Cat 6 UTP cable is typically 25 pounds (110 N). Exceeding this tension can stretch the conductors, damage the insulation, and alter the critical twist ratios that Cat 6 cable relies upon for its performance characteristics. Always use proper cable-pulling techniques to avoid damage.

9Which Alaska division within DCCED specifically handles contractor licensing?

A.Division of Banking & Securities

B.Division of Insurance

C.Division of Corporations, Business & Professional Licensing

D.Division of Economic Development

Explanation: The Division of Corporations, Business & Professional Licensing (CBPL) within Alaska's Department of Community & Economic Development handles all professional contractor licensing, including the Low Voltage Alarm or Signaling Device Contractor license. CBPL processes applications, administers exams, and enforces licensing requirements.

10What is the minimum bend radius for a standard 4-pair Cat 6 UTP cable?

A.1 inch

B.2 inches

C.4 times the cable diameter

D.10 times the cable diameter

Explanation: The minimum bend radius for 4-pair UTP cable is 4 times the cable's outside diameter per TIA-568 standards. For Cat 6 cable, this is approximately 1 inch. Exceeding the bend radius can cause pair untwisting, impedance mismatches, and signal degradation that impacts network performance.

About the Alaska Low Voltage Practice Exam

This is a state-focused diagnostic practice route for Alaska low-voltage and limited-energy concepts, not an official exam with one statewide format. The controlling credential may be a contractor classification, individual technician license, alarm or fire-alarm credential, telecommunications credential, or local registration. Verify the exact scope, regulator, adopted code, and exam bulletin before relying on logistics.

Exam sponsor: Alaska Department of Commerce, Community, and Economic Development — CBPL; other state or local authorities may apply by scope. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

State-focused diagnostic practice; the official assessment structure depends on the exact Alaska credential and regulator.

Time Limit

Varies by exact credential and exam provider

Passing Score

Not published as one generic-route percentage; verify the exact credential

Exam / Certification Fees

Varies by exact credential and current fee schedule
