1. Which NFPA standard primarily governs fire alarm and signaling systems?
A. NFPA 13
B. NFPA 25
C. NFPA 72
D. NFPA 101
Italicized rationale: NFPA 72 is the National Fire Alarm and Signaling Code
that covers design, installation, testing, and maintenance.
2. What is the primary purpose of a fire alarm control unit (FACU)?
A. Detect smoke
B. Receive signals and initiate outputs
C. Notify occupants directly
D. Supply primary power
Italicized rationale: The FACU processes input signals and controls
notification and auxiliary functions.
3. Which device is classified as an initiating device?
A. Horn
B. Strobe
C. Smoke detector
D. Annunciator
Italicized rationale: Initiating devices detect fire-related conditions.
,4. Addressable fire alarm systems differ from conventional systems because
they:
A. Use AC power only
B. Identify individual device locations
C. Eliminate control panels
D. Do not require wiring
Italicized rationale: Addressable systems assign unique addresses to
devices.
5. What is the minimum standby power duration for a protected premises fire
alarm system (non-voice)?
A. 4 hours
B. 12 hours
C. 24 hours
D. 72 hours
Italicized rationale: NFPA 72 requires 24 hours of standby plus 5 minutes
of alarm.
6. Which circuit connects initiating devices to the FACU?
A. NAC
B. IDC
C. SLC
D. RAC
Italicized rationale: Initiating Device Circuits carry signals from detectors
and switches.
7. A Class A circuit is characterized by:
A. One-way wiring
B. Return path to the panel
C. No supervision
D. Wireless operation
Italicized rationale: Class A circuits provide redundancy with a return loop.
8. Which detector is best suited for detecting flaming fires?
A. Ionization smoke
B. Photoelectric smoke
C. Flame detector
, D. Heat detector
Italicized rationale: Flame detectors sense ultraviolet or infrared radiation
from flames.
9. Manual pull stations are required to be installed at what maximum height
to the operable part?
A. 36 inches
B. 48 inches
C. 54 inches
D. 60 inches
Italicized rationale: NFPA 72 limits pull station height to 48 inches.
10.What color is typically used for fire alarm notification appliance circuits?
A. Blue
B. Red
C. Yellow
D. Green
Italicized rationale: Red wiring commonly identifies fire alarm circuits.
11.Which document specifies inspection and testing frequencies for fire alarm
systems?
A. NEC
B. NFPA 72
C. NFPA 13
D. IBC
Italicized rationale: NFPA 72 includes detailed ITM requirements.
12.What is the function of an end-of-line resistor?
A. Increase voltage
B. Supervise circuit integrity
C. Reduce current
D. Provide backup power
Italicized rationale: EOL resistors allow the panel to detect opens and
shorts.
