1. Which device is primarily used to detect smoke in a fire alarm system?
a. Heat detector
b. Pull station
c. Smoke detector (correct answer)
d. Horn/strobe
Rationale:
Smoke detectors sense the presence of smoke particles in the air, providing early
warning before flames are visible.
2. What is the main function of a fire alarm control panel (FACP)?
a. Extinguish the fire automatically
b. Monitor initiating devices and control notification appliances (correct answer)
c. Provide building access
d. Measure air quality
Rationale:
The FACP receives signals from detectors and manual pull stations and activates
alarms or suppression systems as needed.
,3. In a supervised fire alarm system, how often should communication circuits be
tested?
a. Every 12 months
b. Every 6 months (correct answer)
c. Every month
d. Only after installation
Rationale:
NFPA standards require semi-annual testing of communication circuits to ensure
reliability and compliance.
4. Which of the following is considered an initiating device in a fire alarm
system?
a. Horn/strobe
b. Manual pull station (correct answer)
c. Control panel
d. Sprinkler valve
Rationale:
Initiating devices detect a fire or emergency and send a signal to the FACP; manual
pull stations allow human activation.
5. What is the purpose of a notification appliance in a fire alarm system?
a. Detect fire
b. Control sprinkler flow
c. Alert occupants (correct answer)
d. Monitor battery life
Rationale:
Notification appliances such as horns and strobes inform occupants of a fire or
emergency situation, facilitating safe evacuation.
,6. Which type of detector responds to rapid increases in temperature?
a. Smoke detector
b. Rate-of-rise heat detector (correct answer)
c. Carbon monoxide detector
d. Pull station
Rationale:
Rate-of-rise heat detectors activate when the temperature increases rapidly, even if the
maximum temperature is not reached.
7. What is the primary purpose of a supervisory signal in a fire alarm system?
a. Notify fire department
b. Indicate abnormal system condition requiring attention (correct answer)
c. Trigger sprinklers
d. Evacuate building
Rationale:
Supervisory signals alert building personnel to abnormal conditions, such as a valve
being closed, that could impair system operation.
8. Which wiring method is commonly used for connecting fire alarm devices in a
modern system?
a. Fiber optic only
b. Twisted pair only
c. Class A or Class B circuits (correct answer)
d. Coaxial cables
Rationale:
Class A and Class B circuits allow for reliable monitoring of devices, with Class A
providing end-to-end supervision in case of a break.
, 9. What is the minimum audibility level required for fire alarm notification
appliances in sleeping areas?
a. 50 dBA
b. 75 dBA (correct answer)
c. 60 dBA
d. 90 dBA
Rationale:
NFPA 72 requires a minimum of 75 dBA in sleeping areas to ensure occupants are
awakened during an emergency.
10. Which component monitors the integrity of the fire alarm wiring and
devices?
a. Pull station
b. Horn/strobe
c. Fire alarm control panel (correct answer)
d. Sprinkler head
Rationale:
The FACP continuously supervises circuits and devices to detect faults such as open
or short circuits.
11. In a sprinkler system connected to a fire alarm, which device signals the
alarm when water flows?
a. Smoke detector
b. Heat detector
c. Flow switch (correct answer)
d. Pull station
