1. What is the primary purpose of a fire alarm control panel (FACP)?
A. To supply water to sprinkler systems
B. To provide emergency lighting
C. To monitor, control, and indicate the status of the fire alarm system
D. To regulate building temperature
Answer: C. To monitor, control, and indicate the status of the fire
alarm system
Rationale: The fire alarm control panel is the central processing and
supervisory component of a fire alarm system. It receives signals from
initiating devices, processes those signals, activates notification
appliances, and provides system status indications such as alarm,
supervisory, and trouble conditions.
, 2. Which device is specifically designed to detect visible or invisible
products of combustion?
A. Heat detector
B. Smoke detector
C. Manual pull station
D. Waterflow switch
Answer: B. Smoke detector
Rationale: Smoke detectors sense particles or products associated with
combustion. Depending on their design, they may use photoelectric or
other sensing technologies. Heat detectors respond primarily to
temperature conditions rather than smoke.
3. A fire alarm system indicates a supervisory condition. What does
this generally mean?
A. A fire has been confirmed
B. The system has completely failed
C. A monitored fire protection system condition requires attention
D. The building has lost electrical power
Answer: C. A monitored fire protection system condition requires
attention
,Rationale: A supervisory signal commonly indicates an abnormal
condition in a fire protection system, such as a sprinkler control valve
being partially or fully closed. It is different from an alarm signal and
generally does not mean that a fire has been detected.
4. What is the primary function of a manual fire alarm box?
A. Automatically detect smoke
B. Allow an occupant to manually initiate a fire alarm signal
C. Monitor sprinkler pressure
D. Shut down all electrical circuits
Answer: B. Allow an occupant to manually initiate a fire alarm signal
Rationale: Manual fire alarm boxes provide a means for people to
initiate an alarm when they discover a fire or emergency. They are
initiating devices and are typically located in accessible areas along
required means of egress.
5. Which condition is most commonly associated with a fire alarm
trouble signal?
A. Normal system operation
B. An open circuit or wiring fault
C. Activation of a manual pull station
D. Operation of a smoke detector
, Answer: B. An open circuit or wiring fault
Rationale: Trouble signals identify conditions that may impair the fire
alarm system's ability to operate properly. Open circuits, ground faults,
battery problems, loss of power, and equipment failures are common
examples.
6. What is the purpose of an end-of-line device on a conventional
fire alarm initiating circuit?
A. To increase detector sensitivity
B. To supervise the circuit for continuity
C. To amplify the alarm signal
D. To provide emergency illumination
Answer: B. To supervise the circuit for continuity
Rationale: An end-of-line device allows the control panel to monitor the
circuit for abnormal conditions. Changes in circuit resistance caused by
opens or other faults can result in a trouble indication.
7. Which type of detector responds to a rapid increase in
temperature?
A. Rate-of-rise heat detector
B. Photoelectric smoke detector
