1. What is the primary purpose of a fire alarm system?
A. To extinguish a fire automatically
B. To provide early notification of a fire or fire-related emergency
C. To provide electrical power to emergency equipment
D. To replace a building's sprinkler system
Answer: B. To provide early notification of a fire or fire-related
emergency
Rationale: A fire alarm system is primarily intended to detect
conditions associated with fire and provide timely notification so
occupants can evacuate and emergency personnel can respond. It
does not replace fire suppression systems.
, 2. Which component serves as the central processing unit of a
conventional fire alarm system?
A. Manual pull station
B. Notification appliance
C. Fire alarm control unit
D. Smoke detector
Answer: C. Fire alarm control unit
Rationale: The fire alarm control unit receives signals from initiating
devices, processes those signals, supervises system circuits, and
controls notification and other connected functions.
3. What condition exists when a fire alarm system detects an open
circuit on a supervised circuit?
A. Alarm
B. Supervisory
C. Trouble
D. Evacuation
Answer: C. Trouble
Rationale: An open circuit, short circuit, loss of power, or similar
abnormal condition on a supervised circuit normally produces a
,trouble indication. A trouble signal indicates that system integrity
may be compromised.
4. Which device is normally operated manually by a building
occupant who discovers a fire?
A. Heat detector
B. Manual fire alarm box
C. Waterflow switch
D. Duct detector
Answer: B. Manual fire alarm box
Rationale: A manual fire alarm box, commonly called a pull station,
allows a person to manually initiate an alarm signal when a fire or
emergency is discovered.
5. What is the primary function of a smoke detector?
A. Detect smoke particles or products of combustion
B. Measure water pressure
C. Detect electrical current
D. Suppress a fire
Answer: A. Detect smoke particles or products of combustion
, Rationale: Smoke detectors are initiating devices designed to respond
to smoke or products of combustion. They provide early warning,
particularly during the incipient stages of many fires.
6. Which type of detector responds primarily to a rise in
temperature or a fixed temperature threshold?
A. Smoke detector
B. Heat detector
C. Flame detector
D. Carbon monoxide detector
Answer: B. Heat detector
Rationale: Heat detectors operate when temperature reaches a
specified fixed point, rises at a specified rate, or satisfies another
approved heat-sensing condition.
7. What is the purpose of supervision on a fire alarm initiating
circuit?
A. To increase the voltage supplied to detectors
B. To detect certain circuit faults
C. To prevent all false alarms
D. To increase the sound level of notification appliances
Answer: B. To detect certain circuit faults
