Fire Alarm Installer Licensing Exam – 100 Practice
Questions (With Answers & Explanations)
1. What is the primary standard governing fire alarm system
installation in the U.S.?
A. NFPA 54
B. NFPA 90A
C. NFPA 72
D. NFPA 10
NFPA 72 is the National Fire Alarm and Signaling Code and governs
installation and maintenance of fire alarm systems.
2. A fire alarm control panel (FACP) must be connected to which type
of circuit for primary power?
A. Shared lighting circuit
B. Dedicated branch circuit
C. GFCI-protected branch circuit
D. Any 20-amp circuit
A dedicated branch circuit ensures uninterrupted power and prevents
accidental shutoff.
3. What is the minimum secondary power requirement for most
commercial fire alarm systems?
A. 8 hours
B. 24 hours standby + 5 minutes alarm
C. 12 hours
,D. 48 hours
NFPA 72 requires 24 hours standby plus 5 minutes alarm for most
building types.
4. Smoke detectors installed on ceilings must be located at least how
far from walls?
A. 1 inch
B. 4 inches
C. 12 inches
D. 18 inches
NFPA 72 requires at least 4 inches clearance to avoid dead air spaces.
5. Heat detectors operate based on:
A. Ionization
B. Photoelectric scattering
C. Temperature changes
D. CO levels
Heat detectors respond only to temperature changes, not smoke.
6. A spot-type smoke detector covers a maximum of:
A. 900 sq. ft
B. 300–625 sq. ft depending on spacing
C. 150 sq. ft
D. 1000 sq. ft
NFPA 72 lists typical spacing of 30 feet (≈900 sq ft), but actual usable
area is reduced to 300–625 based on various conditions.
, 7. Which detector is best for smoldering fires?
A. Ionization smoke detector
B. Heat detector
C. Photoelectric smoke detector
D. Beam detector
Photoelectric detectors excel at detecting larger particles from
smoldering fires.
8. Manual pull stations must be mounted at what height?
A. 36–42 inches
B. 42–48 inches
C. 52–56 inches
D. 60 inches
NFPA 72 specifies 42–48 inches from the finished floor for accessibility.
9. What color must a manual pull station be?
A. Blue
B. Yellow
C. Green
D. Red
NFPA requires red for easy visibility and standardization.
10. Notification appliances producing audible alarms must have a
minimum level of:
A. 55 dBA
B. 15 dBA above ambient
C. 25 dBA above ambient
