1. What is the primary purpose of an alarm system?
A. To replace law enforcement
B. To detect and alert of unauthorized entry or hazards
C. To monitor building temperature
D. To control lighting
Rationale: The main function of alarm systems is to detect intrusions, fire,
or other hazards and provide alerts for security and safety.
2. Which of the following is a key component of a burglar alarm system?
A. Air pressure sensor
B. Motion detector
C. Smoke detector
D. Fire alarm bell
,Rationale: Burglar alarms commonly use motion detectors to sense
unauthorized movement within a protected area.
3. The control panel in an alarm system primarily functions to:
A. Supply power to the sensors
B. Process signals from sensors and activate alarms
C. Store video footage
D. Control building lighting
Rationale: The control panel receives and interprets input from sensors and
triggers alarm outputs accordingly.
4. A closed-circuit alarm loop means:
A. The circuit is connected to external networks
B. The circuit is complete under normal conditions
C. The circuit is broken during normal conditions
D. The system uses wireless signals
Rationale: In a closed-circuit loop, the electrical path is complete until
interrupted by intrusion, triggering the alarm.
5. What type of sensor detects the breaking of glass?
A. Ultrasonic sensor
B. Acoustic sensor
,C. Infrared sensor
D. Temperature sensor
Rationale: Acoustic sensors detect specific sound frequencies produced
when glass breaks.
6. Which power supply component provides backup in case of main power
failure?
A. Transformer
B. Battery backup
C. Voltage regulator
D. Rectifier
Rationale: A backup battery ensures continuous operation when primary
power is lost.
7. NFPA 72 primarily governs:
A. Electrical wiring methods
B. Fire alarm systems installation and maintenance
C. Burglar alarm licensing
D. CCTV operations
Rationale: NFPA 72 is the National Fire Alarm and Signaling Code, outlining
fire alarm system standards.
, 8. What type of cable is commonly used for alarm circuits?
A. Coaxial
B. Twisted pair
C. Fiber optic
D. Flat ribbon
Rationale: Twisted pair cable reduces electromagnetic interference and is
standard for alarm wiring.
9. Which of the following provides protection against voltage surges?
A. Breaker
B. Fuse
C. Surge protector
D. Transformer
Rationale: Surge protectors divert excess voltage to prevent damage to
system components.
10. A Normally Closed (NC) contact in an alarm circuit will:
A. Be open when system is armed
B. Stay closed until an alarm condition occurs
C. Stay open under all conditions
D. Require manual reset
Rationale: NC contacts maintain a closed path until the circuit is
interrupted by intrusion or fault.
