Burglar & Security Alarm Technician License Exam Practice Test Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary purpose of a burglar alarm system?
• To record video evidence
• To regulate building temperature
• To detect unauthorized entry
• To monitor energy consumption

Rationale: Burglar alarm systems are designed specifically to detect and

alert to unauthorized entry.

• Which sensor detects changes in heat signatures?
• Magnetic contact
• Glass-break sensor
• Passive infrared (PIR) sensor 1 / 4

• Ultrasonic sensor

Rationale: PIR sensors detect motion by sensing infrared heat changes.

3. A closed-circuit system means the alarm:

• Sends alerts to a central station
• Uses only wireless devices
• Activates only when a circuit is opened
• Is connected to a video feed

Rationale: Closed-circuit systems trigger when the circuit is broken by

opening a door/window.

• Which code governs electrical installations for alarm systems?

A. OSHA

B. NEC

C. NFPA 25

D. UL 610

Rationale: Alarm wiring and electrical requirements fall under the National

Electrical Code.

• What is the standard voltage for most low-voltage alarm systems?

A. 120V

B. 12V–24V

C. 60V

D. 240V 2 / 4

Rationale: Burglar alarms generally operate on low-voltage circuits

between 12V and 24V.

• What device detects broken window frequency patterns?
• PIR sensor
• Glass-break sensor
• Shock sensor
• Magnetic contact

Rationale: Glass-break sensors listen for specific sound frequencies created

when glass breaks.

7. Hardwired alarm systems are best suited for:

• Temporary structures
• Mobile homes
• Permanent building installations
• Portable kiosks

Rationale: Hardwired systems require permanent infrastructure and stable

construction environments.

• Which component stores keypad and sensor programming?
• Siren
• Transformer
• Control panel
• Backup battery 3 / 4

Rationale: The control panel functions as the alarm system’s central brain

and stores configurations.

9. An EOL resistor is used to:

• Increase alarm sound
• Supervise circuit integrity
• Power wireless devices
• Detect fire

Rationale: End-of-line resistors help monitor wiring tampering and circuit

continuity.

• What does UL listing indicate?
• Made in the USA
• Weather resistant
• Tested for safety and performance
• Wi-Fi compatible

Rationale: UL listing confirms products meet recognized safety and

reliability standards.

• What type of alarm communicates with a monitoring center?
• Local alarm
• Standalone system
• Central-station alarm
• Silent alarm only
