1. A fire alarm system is primarily designed to:
A. Extinguish fires automatically
B. Detect and notify occupants of fire conditions
C. Provide emergency lighting only
D. Control HVAC systems
Correct Answer: B
Rationale: Fire alarm systems are designed to detect signs of fire such as
smoke or heat and alert occupants and monitoring services. They do not
primarily extinguish fires or serve as general building control systems.
2. Which NFPA standard governs fire alarm systems?
A. NFPA 10
B. NFPA 70
C. NFPA 72
D. NFPA 101
Correct Answer: C
Rationale: NFPA 72 is the National Fire Alarm and Signaling Code, which
, provides requirements for installation, performance, and maintenance of
fire alarm systems.
3. A conventional fire alarm system is best described as:
A. Fully addressable system
B. Wireless-only system
C. Divided into zones for detection
D. Internet-based system
Correct Answer: C
Rationale: Conventional systems divide the building into zones, making it
possible to identify general alarm areas but not specific device locations.
4. An addressable fire alarm system provides:
A. No location identification
B. Individual device identification
C. Only manual alarm activation
D. HVAC control only
Correct Answer: B
Rationale: Addressable systems allow each device to have a unique
identifier, enabling precise location of alarms.
5. A smoke detector primarily responds to:
A. Heat expansion
B. Flame radiation
C. Particulate combustion products
D. Carbon monoxide only
Correct Answer: C
Rationale: Smoke detectors detect airborne particles produced by
combustion, allowing early warning before visible flames develop.
,6. Heat detectors are best used in:
A. Clean office environments
B. Areas with high smoke but no fire risk
C. Areas where smoke detectors cause false alarms
D. Outdoor open fields only
Correct Answer: C
Rationale: Heat detectors are ideal in environments like kitchens or
garages where smoke detectors might falsely trigger due to non-fire
conditions.
7. A Class B circuit is characterized by:
A. Loop return path
B. No end-of-line resistor
C. No supervision of wiring break at all points
D. Full redundancy loop
Correct Answer: C
Rationale: Class B circuits are not fully redundant and cannot detect open
circuits beyond the last device.
8. A Class A circuit provides:
A. No fault tolerance
B. Full loop redundancy
C. Only manual activation
D. Wireless communication
Correct Answer: B
Rationale: Class A circuits return to the control panel, allowing continued
operation even if a wire break occurs.
9. The end-of-line resistor is used to:
A. Increase voltage
, B. Supervise circuit integrity
C. Amplify alarm signal
D. Reduce smoke sensitivity
Correct Answer: B
Rationale: It allows the panel to detect whether a circuit is open, closed,
or in fault condition.
10.Notification appliances include:
A. Only control panels
B. Smoke detectors
C. Horns, strobes, and speakers
D. Circuit breakers
Correct Answer: C
Rationale: Notification appliances alert occupants through audible and
visual signals such as horns and strobes.
11.A fire alarm control panel (FACP) is responsible for:
A. Supplying sprinkler water
B. Monitoring and controlling system inputs and outputs
C. Cooling electrical rooms
D. Generating building power
Correct Answer: B
Rationale: The FACP is the central processing unit of the fire alarm system,
managing detection and notification signals.
12.A pull station is classified as:
A. Automatic detection device
B. Manual initiating device
C. Notification appliance
D. Power supply device
