1. Which of the following devices is considered an initiating device in a
fire alarm system?
A) Horn/strobe
B) Smoke detector
C) Control panel
D) Notification appliance
Answer: B) Smoke detector
Rationale: Initiating devices detect fire conditions and send signals to
the control panel, while notification appliances alert occupants.
2. What is the primary purpose of a fire alarm control panel (FACP)?
A) Sound alarms
B) Activate sprinklers
C) Monitor initiating devices and control outputs
D) Detect smoke
Answer: C) Monitor initiating devices and control outputs
Rationale: The FACP receives signals from detectors and initiates
appropriate responses, including notification appliances and
suppression systems.
3. Which type of smoke detector is most sensitive to slow-smoldering
fires?
A) Ionization
B) Photoelectric
C) Heat detector
D) Carbon monoxide detector
Answer: B) Photoelectric
, Rationale: Photoelectric detectors respond faster to larger smoke
particles typical of smoldering fires.
4. Which fire alarm system class allows devices to operate independently
of the wiring loop?
A) Class A
B) Class B
C) Addressable
D) Conventional
Answer: B) Class B
Rationale: Class B circuits have devices wired in a single path, which
stops at the end-of-line resistor.
5. Which component is required at the end of a Class B initiating device
circuit?
A) Fuse
B) Breaker
C) End-of-line resistor
D) Relay
Answer: C) End-of-line resistor
Rationale: It allows the control panel to supervise the circuit for opens
and shorts.
6. What is the primary difference between an addressable and a
conventional fire alarm system?
A) Voltage
B) Wiring type
C) Individual device identification
D) Power source
Answer: C) Individual device identification
Rationale: Addressable systems assign unique addresses to each
device, allowing precise location identification.
7. What is the minimum sound level for a fire alarm notification appliance
in an occupied area?
A) 50 dBA
B) 65 dBA
C) 75 dBA
D) 90 dBA
Answer: C) 75 dBA
, Rationale: NFPA 72 requires 75 dBA at the bed or floor level in
sleeping areas.
8. Which type of fire detector responds primarily to heat?
A) Ionization smoke detector
B) Rate-of-rise heat detector
C) Carbon monoxide detector
D) Photoelectric smoke detector
Answer: B) Rate-of-rise heat detector
Rationale: Heat detectors respond to temperature increase, either at a
fixed point or by rate of rise.
9. What is the purpose of a notification appliance circuit (NAC)?
A) Detect smoke
B) Activate horns, strobes, or speakers
C) Supervise wiring
D) Monitor sprinklers
Answer: B) Activate horns, strobes, or speakers
Rationale: NACs provide power and control to notification appliances.
10. Which NFPA standard covers the installation of fire alarm
systems?
A) NFPA 13
B) NFPA 14
C) NFPA 72
D) NFPA 101
Answer: C) NFPA 72
Rationale: NFPA 72 is the National Fire Alarm and Signaling Code.
11. In a fire alarm system, a horn/strobe is considered what type of
device?
A) Initiating
B) Supervisory
C) Notification appliance
D) Control
Answer: C) Notification appliance
Rationale: Notification appliances alert occupants to evacuate.
12. Which type of smoke detector is more prone to false alarms from
cooking?
A) Photoelectric
B) Ionization
