Question 1
What is the primary purpose of a fire alarm control panel (FACP)?
A. To provide normal building lighting
B. To distribute utility power throughout the building
C. To receive signals from initiating devices and control notification and
other connected functions
D. To regulate the building's HVAC temperature
Answer: C. To receive signals from initiating devices and control
notification and other connected functions
Rationale: The fire alarm control panel is the central processing unit of
a fire alarm system. It supervises initiating devices, processes alarm
and trouble signals, activates notification appliances, and may control
,connected emergency functions such as elevator recall or HVAC
shutdown.
Question 2
Which device is normally used to manually initiate a fire alarm?
A. Smoke detector
B. Manual fire alarm box
C. Heat detector
D. Notification appliance
Answer: B. Manual fire alarm box
Rationale: A manual fire alarm box, commonly called a pull station,
allows an occupant to initiate an alarm manually. It is an initiating
device rather than a notification appliance.
Question 3
What is the principal function of a smoke detector in a fire alarm
system?
A. To extinguish a fire
B. To detect smoke particles associated with combustion
,C. To provide emergency lighting
D. To supply standby power
Answer: B. To detect smoke particles associated with combustion
Rationale: Smoke detectors are initiating devices designed to detect
particles of combustion. Depending on the technology, they may use
photoelectric or other sensing methods to identify smoke conditions
and transmit an alarm signal to the control unit.
Question 4
A conventional fire alarm initiating circuit generally identifies:
A. The exact individual address of every detector
B. A zone or circuit condition rather than the exact device location
C. The voltage of the utility service
D. The manufacturer's serial number of every device
Answer: B. A zone or circuit condition rather than the exact device
location
Rationale: Conventional systems typically divide devices into zones or
circuits. When an initiating device operates, the panel generally
identifies the affected zone rather than communicating the unique
address of the individual device.
, Question 5
What is a major advantage of an addressable fire alarm system?
A. It eliminates the need for initiating devices
B. It identifies individual devices or points on the system
C. It does not require supervision
D. It operates without a control panel
Answer: B. It identifies individual devices or points on the system
Rationale: Addressable systems assign individual identification to
system devices or points. This allows the control panel to provide
more specific information about the location or condition of an alarm,
supervisory, or trouble signal.
Question 6
What does a supervisory signal generally indicate?
A. A condition involving a fire suppression or other supervised system
that requires attention
B. A confirmed building fire
