1. Which of the following devices is used to detect smoke using a
light-scattering principle?
A. Ionization smoke detector
B. Beam detector
C. Photoelectric smoke detector
D. Heat detector
Photoelectric smoke detectors use a light source and a photodetector
to sense smoke particles scattering light. This method is effective for
detecting smoldering fires.
2. What is the primary purpose of a fire alarm control panel (FACP)?
A. To supply power to the building
B. To regulate sprinklers
C. To monitor and control fire alarm initiating devices and
, notification appliances
D. To detect gas leaks
The FACP serves as the central hub of a fire alarm system, monitoring
initiating devices such as smoke and heat detectors and activating
notification appliances when needed.
3. Which type of initiating device is most suitable for areas prone to
rapid flaming fires?
A. Ionization smoke detector
B. Heat detector
C. Photoelectric smoke detector
D. Duct detector
Heat detectors respond to high temperatures and rapid rises in
temperature, making them ideal for detecting fast-flaming fires.
4. Which signaling method is typically used for transmitting signals
from a fire alarm control panel to a remote monitoring station?
A. Wireless RF only
B. Telephone line or IP-based communication
C. Local horn/strobe only
D. Audio speaker network
,Remote monitoring of fire alarm systems usually occurs via telephone
circuits or IP networks to ensure immediate response from a central
monitoring station.
5. A duct smoke detector is installed to:
A. Detect smoke in open areas
B. Detect smoke within HVAC ductwork
C. Activate sprinkler systems
D. Monitor heat in a kitchen
Duct smoke detectors monitor the airflow within heating, ventilation,
and air conditioning ducts to prevent smoke from circulating through
the building.
6. Which fire alarm notification appliance is required to provide both
audible and visible alerts in areas with hearing-impaired
occupants?
A. Horn
B. Bell
C. Horn/strobe combination
D. Chime
Areas with hearing-impaired occupants must use notification
appliances that include visual alerts, typically a strobe, along with
audible devices.
, 7. What is the primary difference between a Class A and Class B fire
alarm circuit?
A. Voltage rating
B. Current rating
C. Circuit continuity in the event of a single open or short
D. Number of devices
Class A circuits provide a path back to the control panel if the wiring is
broken, maintaining circuit integrity, whereas Class B circuits do not.
8. Which standard specifies the installation requirements for fire
alarm systems in the United States?
A. NFPA 13
B. NFPA 72
C. NFPA 70
D. UL 864
NFPA 72, the National Fire Alarm and Signaling Code, sets the
standards for the design, installation, and maintenance of fire alarm
systems.
9. What is the main advantage of using an addressable fire alarm
system over a conventional system?
A. Lower installation cost
B. Individual device identification and status monitoring
