1. Which NFPA standard primarily governs the installation of fire alarm
systems used for life safety?
A. NFPA 70
B. NFPA 13
C. NFPA 72
D. NFPA 101
Rationale: NFPA 72 is the National Fire Alarm and Signaling Code and
is the principal standard for design, installation, and maintenance of
fire alarm systems.
2. What type of initiating device is most effective at detecting a
smoldering fire in its early stage?
A. Ionization smoke detector
B. Photoelectric smoke detector
C. Heat detector
D. Manual pull station
Rationale: Photoelectric detectors respond well to larger smoke
particles from smoldering fires, providing earlier warning in such
conditions.
3. According to NFPA 72, what is the minimum decibel level required for
notification appliances in sleeping areas above ambient sound?
A. 5 dB
B. 10 dB
, C. 15 dB
D. 20 dB
Rationale: NFPA 72 requires notification appliances to produce at
least 15 dB above the average ambient sound level in sleeping areas.
4. What is the primary purpose of a fire alarm control unit (FACU)?
A. Supply backup power
B. Monitor sprinkler flow
C. Receive and process initiating signals
D. Provide voice communication
Rationale: The FACU monitors initiating devices, processes signals,
and controls notification and signaling functions of the system.
5. In a supervised fire alarm circuit, what condition will indicate a wiring
fault?
A. Alarm signal
B. Trouble signal
C. Supervisory signal
D. Silence
Rationale: A trouble signal is used to indicate faults like open or
short circuits in supervised fire alarm wiring.
6. Requirements for emergency power supply in fire alarm systems are
found in which section of NFPA 72?
A. Chapter 5
B. Chapter 10
C. Chapter 12
D. Annex A
Rationale: Chapter 10 of NFPA 72 details the requirements for power
supplies, including primary and secondary power for fire alarm
systems.
7. What is the minimum spacing for smoke detectors in a typical corridor
according to NFPA 72?
A. 10 ft
B. 30 ft
C. 50 ft
D. 75 ft
, Rationale: NFPA 72 generally allows a maximum spacing of 30 ft
between smoke detectors in corridors to achieve effective coverage.
8. What type of circuit is used to power notification appliances like horns
and strobes?
A. Initiating Device Circuit
B. Notification Appliance Circuit
C. Supervisory Circuit
D. Ground Fault Loop
Rationale: Notification Appliance Circuits are designated to power
audible and visible notification devices in fire alarm systems.
9. A system that transmits signals and supervisory information to a
remote monitoring location is known as:
A. Local system
B. Central control system
C. Remote station system
D. Proprietary system
Rationale: Remote station systems send signals to a remote
monitoring facility for off-premises supervision.
10. What initiates a supervisory signal in a fire alarm system?
A. Manual pull station activation
B. Detector alarm
C. Sprinkler valve tamper
D. Strobe activation
Rationale: Tamper conditions on sprinkler valves typically generate
supervisory signals indicating a change in system readiness.
11. The term “Addressable device” refers to a device that:
A. Has a unique location listed on plans
B. Uses analog current levels
C. Can be individually recognized by the system
D. Operates on battery only
Rationale: Addressable devices communicate specific ID information
to the fire alarm control unit for individual device status.
12. What is the maximum allowable voltage drop on a NAC at
maximum load?
A. 1 V
