1. What is the primary purpose of a fire sprinkler system?
A. To detect fire and sound an alarm
B. To suppress fire and minimize property damage
C. To ventilate smoke from buildings
D. To provide water for firefighting hoses
Correct Answer: B. To suppress fire and minimize property damage
Rationale: Sprinkler systems are designed to automatically control or extinguish
fires, protecting life and property. Detection and alarming are primarily handled by
fire alarm systems, not the sprinkler system itself.
2. Which type of sprinkler head is most commonly used in commercial buildings?
A. Dry pendant
B. Upright
C. Sidewall
D. Pendent
Correct Answer: D. Pendent
Rationale: Pendent sprinklers hang down from the ceiling and are the most
common type used in commercial spaces with finished ceilings. Upright sprinklers
are more common in areas with exposed piping or open ceilings .
,3. What is the minimum water supply pressure required for a standard wet-pipe
sprinkler system in a light hazard occupancy?
A. 7 psi
B. 15 psi
C. 20 psi
D. 30 psi
Correct Answer: B. 15 psi
Rationale: Massachusetts requires a minimum residual pressure of 15 psi for light
hazard fire sprinkler systems. A pressure of 7 psi is insufficient for any system,
while higher pressures of 20 psi or 30 psi exceed the minimum requirement .
4. What is the most common type of sprinkler system in use today?
A. Dry-pipe system
B. Pre-action system
C. Wet-pipe system
D. Deluge system
Correct Answer: C. Wet-pipe system
Rationale: Wet-pipe systems are the most common because they are the simplest,
most reliable, and least expensive to maintain. Water is always present in the pipes,
allowing for immediate discharge upon sprinkler activation .
5. What component keeps water out of a dry-pipe system until a sprinkler
activates?
A. Backflow preventer
B. Dry-pipe valve
C. Pressure relief valve
D. Check valve
,Correct Answer: B. Dry-pipe valve
Rationale: The dry-pipe valve is a specialized valve that holds water back from the
system piping. The piping is filled with pressurized air or nitrogen. When a
sprinkler opens, the air pressure drops, allowing the valve to open and water to
flow into the system .
6. Which fire sprinkler system is designed to operate in freezing temperatures?
A. Wet-pipe
B. Dry-pipe
C. Pre-action
D. Deluge
Correct Answer: B. Dry-pipe
Rationale: Dry-pipe systems are designed for unheated areas where water in pipes
would freeze and cause damage. The pipes are filled with pressurized air, and
water is held back by the dry-pipe valve until a fire activates a sprinkler .
7. What device triggers a sprinkler head to discharge water?
A. Smoke detector
B. Heat-sensitive element
C. Pressure switch
D. Manual pull station
Correct Answer: B. Heat-sensitive element
Rationale: Sprinkler heads are activated by heat, not smoke. A fusible link (metal
alloy) melts or a glass bulb breaks when the surrounding air reaches a
predetermined temperature, releasing a cap and allowing water to flow .
8. Which NFPA standard covers the installation of fire sprinkler systems?
A. NFPA 13
, B. NFPA 25
C. NFPA 72
D. NFPA 70
Correct Answer: A. NFPA 13
Rationale: NFPA 13, the Standard for the Installation of Sprinkler Systems, is the
primary code governing the design, installation, and water supply requirements for
fire sprinkler systems .
9. Which NFPA standard covers the inspection, testing, and maintenance of
sprinkler systems?
A. NFPA 13
B. NFPA 25
C. NFPA 72
D. NFPA 70
Correct Answer: B. NFPA 25
Rationale: NFPA 25, the Standard for the Inspection, Testing, and Maintenance of
Water-Based Fire Protection Systems, establishes the minimum requirements for
the ongoing inspection, testing, and maintenance of sprinkler systems .
10. What is the maximum spacing for standard pendent sprinklers in a light-hazard
occupancy per NFPA 13?
A. 10 ft
B. 12 ft
C. 15 ft
D. 20 ft
Correct Answer: C. 15 ft
