1Which Arizona state agency issues the C-12 Low Voltage Communication Systems license?

A.Arizona Department of Real Estate

B.Arizona Registrar of Contractors (ROC)

C.Arizona Corporation Commission

D.Arizona Department of Administration

Explanation: The Arizona Registrar of Contractors (ROC) issues the C-12 Low Voltage Communication Systems license. The ROC regulates the construction industry in Arizona, processing license applications, investigating complaints, and enforcing contractor licensing laws.

2What is the Arizona C-12 license classification specifically for?

A.General electrical work

B.Low Voltage Communication Systems

C.Plumbing systems

D.HVAC systems

Explanation: The Arizona C-12 classification covers Low Voltage Communication Systems. This license allows contractors to install, alter, and repair low voltage systems including fire alarms, security systems, structured cabling, audio/video systems, and other communication systems operating at low voltage levels.

3What is the difference between the Arizona C-12 and L-67 license classifications?

A.C-12 is commercial only; L-67 is residential only

B.C-12 covers communication systems; L-67 is a limited residential low voltage classification

C.They are identical licenses

D.C-12 is for new construction; L-67 is for remodeling

Explanation: The C-12 license covers Low Voltage Communication Systems for commercial and residential projects without limitation. The L-67 is a limited residential classification. Both are issued by the Arizona Registrar of Contractors, but the L-67 has scope limitations for residential low voltage work.

4Under NEC Article 725, what are the three classifications of remote-control, signaling, and power-limited circuits?

A.Type A, Type B, Type C

B.Class 1, Class 2, Class 3

C.Level 1, Level 2, Level 3

D.Grade 1, Grade 2, Grade 3

Explanation: NEC Article 725 classifies remote-control, signaling, and power-limited circuits into Class 1, Class 2, and Class 3. Class 1 circuits can operate up to 600V and follow standard wiring methods. Class 2 and Class 3 circuits are power-limited and have reduced installation requirements due to their inherent safety.

5What NEC article governs the installation of fire alarm system wiring?

A.Article 700

B.Article 725

C.Article 760

D.Article 800

Explanation: NEC Article 760 covers fire alarm system wiring, including both power-limited fire alarm (PLFA) and non-power-limited fire alarm (NPLFA) circuits. This article addresses cable types, installation methods, separation requirements, and other provisions specific to fire alarm system wiring.

6In Arizona, what bonding requirement applies to contractors holding a C-12 license?

A.No bond required

B.A surety bond is required as determined by the ROC

C.Only a cash deposit is accepted

D.Bonding is only required for projects over $100,000

Explanation: Arizona requires C-12 licensed contractors to maintain a surety bond as determined by the Registrar of Contractors. The bond amount is based on the contractor's volume of work and provides financial protection for consumers. Failure to maintain the required bond can result in license suspension.

7What is the maximum voltage for a Class 2 power source per NEC Article 725?

A.30 volts

B.60 volts

C.100 volts

D.150 volts

Explanation: Class 2 power sources are limited to a maximum of 100 volts per NEC Chapter 9, Table 11(A). However, the current and power are also limited. Most practical Class 2 applications use 12V or 24V DC power supplies. The power limitation allows simplified wiring methods for these circuits.

8Which type of cable must be used for installations in plenum air-handling spaces?

A.CM rated cable

B.CMR riser rated cable

C.CMP plenum rated cable

D.CMX limited use cable

Explanation: CMP (Communications Plenum) rated cable must be used in plenum air-handling spaces. Plenum cable has fire-resistant and low-smoke properties that minimize toxic fume production if the cable burns. Using non-plenum cable in these spaces violates the NEC and building codes.

9What is an end-of-line (EOL) resistor used for in a fire alarm initiating device circuit?

A.To increase signal strength

B.To provide circuit supervision by maintaining a known current flow

C.To reduce voltage to devices

D.To filter noise on the circuit

Explanation: An EOL resistor is placed at the last device on a fire alarm initiating device circuit to provide supervision. The fire alarm control panel monitors the steady-state current through the resistor. An open circuit (broken wire) causes loss of current, and a short circuit causes excess current — both generate a trouble condition on the panel.

10What is the maximum horizontal cable run length per TIA-568 standards?

A.50 meters

B.75 meters

C.90 meters

D.100 meters

Explanation: TIA-568 specifies a maximum horizontal cable run of 90 meters from the telecommunications room to the work area outlet. The remaining 10 meters of the 100-meter total channel is allocated for patch cords and equipment cords at both ends. This distance limitation applies to all categories of UTP copper cable.

About the Arizona Low Voltage Practice Exam

This is a state-focused diagnostic practice route for Arizona 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: Arizona Registrar of Contractors; 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 Arizona credential and regulator.
