1. Which document provides the highest-level guidance for
integrating fire alarm systems with mass notification systems?
A. NFPA 72 Annex A
B. NFPA 101
C. NFPA 72 Chapter 24
D. UFC 4-021-01
D
Unified Facilities Criteria provide the overarching design
requirements for mass notification interfacing.
2. During a performance-based design for smoke detection, which
analysis approach is most appropriate?
A. Prescriptive analysis
B. Fire modeling using CFD
C. Historical incident review
D. Vision-based smoke obscuration assessment
B
CFD modeling allows quantitative evaluation of smoke movement
and detector activation times.
,3. A large campus fire alarm network uses peer-to-peer
communication. Which topology is most resilient to single-node
failure?
A. Bus
B. Ring
C. Star
D. Mesh
D
Mesh networks support multiple communication paths, reducing
vulnerability.
4. For a high-value archival facility, which detection method offers
the lowest nuisance alarm rate while providing early warning?
A. Beam smoke detection
B. Aspirating smoke detection (Class A sensitivity)
C. Spot ionization
D. Heat detection
B
Aspirating systems with high sensitivity provide early detection
with tuned nuisance filtering.
5. Which NFPA 72 chapter governs documentation requirements for
complex life safety systems?
A. Chapter 7
B. Chapter 10
C. Chapter 14
D. Chapter 18
A
Chapter 7 outlines design, recordkeeping, and documentation
requirements.
, 6. What is the primary purpose of a signal line circuit isolator?
A. Increase circuit capacity
B. Convert SLC to NAC
C. Separate shorted segments
D. Reduce address counts
C
Isolators confine short circuits to maintain system operation.
7. Which detector technology is best for detecting flaming fires in a
high-airflow turbine room?
A. Photoelectric spot
B. UV flame detector
C. CO detector
D. Aspirating smoke detector
B
UV flame detectors respond rapidly to open flames even with
airflow.
8. What is the maximum recommended delay time for releasing
systems under NFPA 2001?
A. 10 s
B. 30 s
C. 60 s
D. 90 s
B
NFPA 2001 requires a minimum 30-second pre-discharge warning
unless hazards exist.
9. Which item must appear on a Level IV design submittal but not on
Level I installations?
A. Wiring diagrams
B. Sequence of operations matrix
