Question 1
What is the primary purpose of a fire alarm system?
A. To suppress fires automatically
B. To detect and notify occupants of fire conditions
C. To replace sprinkler systems
D. To control building HVAC systems
Correct Answer: B
Rationale: The primary function of a fire alarm system is to detect signs of fire
such as smoke, heat, or flame and provide early warning to occupants and
emergency responders. While some systems interface with suppression or HVAC
systems, their core purpose is life safety notification, not fire suppression or
environmental control.
Question 2
Which NFPA standard governs fire alarm systems?
A. NFPA 70
B. NFPA 72
C. NFPA 101
D. NFPA 13
Correct Answer: B
,Rationale: NFPA 72 is the National Fire Alarm and Signaling Code, which covers
installation, performance, inspection, testing, and maintenance of fire alarm
systems. NFPA 70 is the National Electrical Code, NFPA 101 is Life Safety Code,
and NFPA 13 governs sprinkler systems.
Question 3
Which device is used primarily for early smoke detection?
A. Heat detector
B. Manual pull station
C. Smoke detector
D. Flow switch
Correct Answer: C
Rationale: Smoke detectors are designed to sense airborne combustion particles,
allowing early detection of fire before significant heat buildup. Heat detectors
respond later in fire development, pull stations require human activation, and
flow switches are part of sprinkler systems.
Question 4
What is the typical voltage for commercial fire alarm initiating circuits?
A. 12V DC
B. 24V DC
C. 120V AC
D. 240V AC
Correct Answer: B
Rationale: Most commercial fire alarm systems operate on 24V DC for initiating
device circuits due to safety, reliability, and compatibility with system
components. Higher voltages are generally used for building power, not
initiating circuits.
,Question 5
Which device is manually activated during an emergency?
A. Smoke detector
B. Heat sensor
C. Pull station
D. Beam detector
Correct Answer: C
Rationale: Manual pull stations allow building occupants to activate the fire
alarm system when they observe fire conditions. Smoke, heat, and beam
detectors are automatic initiating devices.
Question 6
Which system component provides audible notification?
A. Relay module
B. Notification appliance
C. Control module
D. Initiating device
Correct Answer: B
Rationale: Notification appliances such as horns, bells, and speakers provide
audible alerts to occupants. Relays and control modules manage signals, while
initiating devices detect fire conditions.
Question 7
What is the function of a fire alarm control panel (FACP)?
A. Suppress fire automatically
B. Monitor and control fire alarm system operations
, C. Provide emergency lighting
D. Operate HVAC systems
Correct Answer: B
Rationale: The FACP is the central processing unit of a fire alarm system,
receiving inputs from initiating devices and activating notification appliances
and control outputs. It does not perform suppression or HVAC control directly.
Question 8
Which type of detector responds to rapid temperature increase?
A. Ionization detector
B. Rate-of-rise heat detector
C. Beam detector
D. Photoelectric detector
Correct Answer: B
Rationale: Rate-of-rise heat detectors activate when temperature increases
quickly over a short period, indicating a developing fire. Ionization and
photoelectric detectors respond to smoke, not heat rate.
Question 9
What is supervised wiring in fire alarm systems?
A. Wiring installed by licensed electricians only
B. Wiring monitored for open or short circuit conditions
C. Wiring hidden inside conduit
D. Wiring connected to sprinkler systems
Correct Answer: B
Rationale: Supervised circuits continuously monitor wiring integrity to detect
faults such as opens, shorts, or ground faults, ensuring system reliability and
safety.
