1. Which of the following is the primary purpose of a fire alarm system?
A. To alert occupants of a fire
B. To automatically extinguish a fire
C. To detect and notify of a fire condition
D. To monitor building temperature
Rationale: The primary purpose of a fire alarm system is to detect the
presence of fire and notify occupants and emergency personnel to allow
timely evacuation and response.
2. What type of fire detector responds to smoke particles in the air?
A. Heat detector
B. Smoke detector
C. Flame detector
D. Gas detector
,Rationale: Smoke detectors sense smoke particles in the air, which are
early indicators of a fire, unlike heat or flame detectors that respond to
other fire signatures.
3. Which class of fire involves ordinary combustibles such as wood, paper,
or cloth?
A. Class B
B. Class C
C. Class A
D. Class D
Rationale: Class A fires involve ordinary combustible materials like wood,
paper, and textiles, and typically require water or multipurpose
extinguishing agents.
4. What NFPA standard governs the installation of fire alarm systems?
A. NFPA 13
B. NFPA 72
C. NFPA 101
D. NFPA 70
Rationale: NFPA 72 is the National Fire Alarm and Signaling Code, which
specifies installation, performance, and maintenance requirements for fire
alarm systems.
5. Which type of fire alarm system is supervised by a central station?
A. Local alarm system
,B. Remote station system
C. Proprietary system
D. Auxiliary system
Rationale: Remote station systems transmit alarm signals to a central
monitoring location, providing off-site supervision and rapid response.
6. Which component in a fire alarm system receives signals from initiating
devices?
A. Notification appliance
B. Power supply
C. Control panel
D. Detector base
Rationale: The fire alarm control panel (FACP) receives signals from
initiating devices like smoke detectors or pull stations and determines the
appropriate response.
7. What is the purpose of a notification appliance in a fire alarm system?
A. To detect fire
B. To monitor wiring integrity
C. To alert occupants of a fire
D. To provide backup power
Rationale: Notification appliances, such as horns, strobes, and speakers,
provide audible and/or visible alerts to building occupants during a fire
condition.
, 8. What type of initiating device is a manual pull station?
A. Automatic
B. Manual
C. Supervisory
D. Auxiliary
Rationale: Manual pull stations require human intervention to activate the
fire alarm system, unlike automatic devices that detect fire conditions
independently.
9. Which of the following is a common type of smoke detector in
commercial systems?
A. Ionization only
B. Photoelectric only
C. Both ionization and photoelectric
D. Heat detector
Rationale: Commercial fire alarm systems often use both ionization and
photoelectric smoke detectors to provide broader fire detection coverage.
10. How often must batteries in a fire alarm system be tested according to
NFPA 72?
A. Every month
B. Every 3 months
C. Annually
D. Every 5 years
