1. What is the primary purpose of a performance-based fire alarm
system design?
A. To minimize installation costs
B. To meet prescriptive code requirements only
C. To achieve specific fire safety objectives
D. To reduce inspection frequency
Answer: C
Rationale: Performance-based design focuses on achieving defined fire
protection goals rather than strictly following prescriptive code
requirements.
,2. Which document provides minimum requirements for fire alarm
system installation?
A. NEC
B. NFPA 13
C. NFPA 72
D. NFPA 101
Answer: C
Rationale: NFPA 72 is the National Fire Alarm and Signaling Code
governing installation, testing, and maintenance.
3. What is the maximum allowable voltage drop for most fire alarm
circuits?
A. 5%
B. 10%
C. 15%
D. 20%
Answer: B
Rationale: NFPA 72 recommends limiting voltage drop to 10% to ensure
proper device operation.
,4. Which type of detector is best suited for detecting smoldering fires?
A. Ionization
B. Photoelectric
C. Heat
D. Flame
Answer: B
Rationale: Photoelectric detectors are more sensitive to larger smoke
particles from smoldering fires.
5. What is the function of an addressable fire alarm system?
A. Identify zones only
B. Identify individual devices
C. Reduce wiring costs only
D. Eliminate control panels
Answer: B
Rationale: Addressable systems allow pinpoint identification of
individual devices.
6. Which circuit type allows multiple devices to communicate with the
control panel using digital signals?
, A. IDC
B. NAC
C. SLC
D. EOL
Answer: C
Rationale: Signaling Line Circuits (SLC) are used in addressable systems
for communication.
7. What is the purpose of an end-of-line resistor?
A. Increase current
B. Monitor circuit integrity
C. Reduce voltage
D. Boost signal
Answer: B
Rationale: It allows the panel to supervise wiring continuity.
8. What is the typical spacing for spot-type smoke detectors on
smooth ceilings?
A. 20 ft
B. 30 ft
