1. What is the primary purpose of a fire alarm system?
A. Control building temperature
B. Detect and report fire-related conditions
C. Provide emergency lighting only
D. Monitor electrical consumption
Answer: Detect and report fire-related conditions
Rationale: A fire alarm system is designed to detect fire or fire-related
conditions and provide notification so occupants and emergency personnel can
respond appropriately.
2. Which component receives signals from initiating devices and processes
them?
A. Notification appliance
B. Manual pull station
C. Fire alarm control unit
D. Smoke detector
Answer: Fire alarm control unit
Rationale: The fire alarm control unit (FACU) is the central component that
receives, processes, supervises, and controls signals from system devices.
, 3. Which device is manually operated to initiate a fire alarm signal?
A. Heat detector
B. Manual fire alarm box
C. Horn
D. Strobe
Answer: Manual fire alarm box
Rationale: A manual fire alarm box, commonly called a pull station, allows a
person to manually initiate an alarm signal.
4. What type of detector responds to products of combustion suspended in
the air?
A. Smoke detector
B. Heat detector
C. Waterflow switch
D. Tamper switch
Answer: Smoke detector
Rationale: Smoke detectors sense airborne particles produced by combustion
and initiate an alarm or supervisory signal depending on the application.
5. Which device typically produces an audible alarm signal?
A. Strobe
B. Horn
C. Pull station
D. Heat detector
Answer: Horn
Rationale: A horn produces an audible notification signal intended to alert
occupants to an emergency condition.
6. What is the purpose of a visual notification appliance?
,A. Detect smoke
B. Monitor sprinkler valves
C. Provide a visible alarm indication
D. Supply standby power
Answer: Provide a visible alarm indication
Rationale: Visual notification appliances, such as strobes, provide a visible signal
for occupant notification.
7. What does a fire alarm system's initiating circuit connect?
A. Notification appliances only
B. Initiating devices to the control unit
C. Batteries to transformers
D. Building lighting to generators
Answer: Initiating devices to the control unit
Rationale: Initiating circuits or signaling line circuits connect devices such as
detectors, pull stations, and supervisory switches to the fire alarm control unit.
8. Which device detects a rise in temperature to initiate an alarm?
A. Smoke detector
B. Heat detector
C. Horn
D. Strobe
Answer: Heat detector
Rationale: Heat detectors respond to temperature conditions, such as a fixed
temperature or rapid temperature increase.
9. What does a sprinkler waterflow switch normally detect?
A. Low battery voltage
B. Movement of water through the sprinkler system
, C. Smoke concentration
D. High room temperature
Answer: Movement of water through the sprinkler system
Rationale: A waterflow switch detects sustained water movement caused by
activation of a sprinkler or another water-discharge event.
10.What is the purpose of a supervisory signal?
A. Indicate a normal system condition
B. Indicate an abnormal condition related to a fire protection system
C. Activate all building lights
D. Silence all notification appliances
Answer: Indicate an abnormal condition related to a fire protection system
Rationale: Supervisory signals indicate conditions such as a closed sprinkler
control valve that could impair fire protection.
11.What does a trouble signal generally indicate?
A. A fire has definitely occurred
B. A system fault or abnormal condition exists
C. The building is fully evacuated
D. A sprinkler has discharged
Answer: A system fault or abnormal condition exists
Rationale: Trouble signals alert personnel to faults such as open circuits, ground
faults, power problems, or equipment malfunctions.
12.Which power source normally provides primary power to a fire alarm
control unit?
A. Building electrical service
B. Portable flashlight
