1. What is the primary purpose of a fire alarm system?
A) To extinguish fires automatically
B) To alert occupants of a fire and initiate response
C) To prevent fire from occurring
D) To inspect building wiring
Answer: B) To alert occupants of a fire and initiate response
Rationale: Fire alarm systems are designed to detect fire, notify occupants, and
prompt emergency response, not to extinguish fires.
2. According to NFPA 72, which type of fire alarm system provides automatic
detection and occupant notification?
A) Manual fire alarm system
B) Automatic fire alarm system
C) Supervisory system
D) Security alarm system
Answer: B) Automatic fire alarm system
Rationale: Automatic systems detect fire using devices like smoke or heat
detectors and notify occupants automatically.
3. What device is commonly used to detect smoke in a building?
A) Pull station
B) Heat detector
C) Smoke detector
D) Bell
Answer: C) Smoke detector
Rationale: Smoke detectors sense smoke particles and are critical for early
warning.
,4. Which type of detector responds to an increase in temperature?
A) Smoke detector
B) Heat detector
C) Carbon monoxide detector
D) Manual pull station
Answer: B) Heat detector
Rationale: Heat detectors activate when a certain temperature or rate of rise is
detected.
5. What is the purpose of a manual pull station?
A) To automatically detect smoke
B) To allow occupants to manually initiate a fire alarm
C) To extinguish a fire
D) To measure air quality
Answer: B) To allow occupants to manually initiate a fire alarm
Rationale: Pull stations provide a manual method for alarm initiation when a
fire is observed.
6. In NFPA 72, what is the minimum audible signal level for occupant
notification?
A) 50 dB
B) 60 dB
C) 75 dB
D) 85 dB
Answer: C) 75 dB
Rationale: NFPA 72 requires fire alarm signals to be audible at a minimum of 75
dB in normally occupied areas.
7. What is the purpose of a fire alarm control panel (FACP)?
A) To extinguish fires automatically
B) To control and monitor the fire alarm system
, C) To provide backup power only
D) To provide ventilation
Answer: B) To control and monitor the fire alarm system
Rationale: The FACP supervises all connected devices, initiates alarms, and
indicates system status.
8. Which type of notification appliance produces light signals for occupants?
A) Horn
B) Bell
C) Strobe
D) Pull station
Answer: C) Strobe
Rationale: Strobes provide visual signals, essential for alerting individuals who
are deaf or hard of hearing.
9. What is a common initiating device in a fire alarm system?
A) Horn
B) Smoke detector
C) Strobe light
D) Speaker
Answer: B) Smoke detector
Rationale: Initiating devices start the alarm sequence when they detect fire
conditions.
10. What type of circuit connects initiating devices to the fire alarm control
panel?
A) Notification appliance circuit
B) Signaling line circuit
C) Initiating device circuit
D) Emergency power circuit
Answer: C) Initiating device circuit
Rationale: Initiating device circuits (IDCs) connect detectors and pull stations to
the FACP.
