1. Which of the following NFPA standards specifically governs the
installation of fire sprinkler systems?
A. NFPA 10
B. NFPA 13
C. NFPA 70
D. NFPA 25
Rationale: NFPA 13 is the standard for the installation of sprinkler
systems, detailing design criteria and installation requirements.
2. What is the primary purpose of a fire sprinkler system?
A. To extinguish the fire before arrival of fire department
B. To alarm occupants of a fire
C. To control or suppress fire at its early stage
D. To pressurize exits for safe egress
Rationale: The main objective of a sprinkler system is to control or
suppress fire early to limit spread and damage.
,3. Which type of sprinkler head is most commonly used in standard light
hazard occupancies?
A. Dry pendant
B. Standard upright or pendent
C. Deluge
D. ESFR
Rationale: Standard upright or pendent sprinkler heads are typical in
light hazard occupancies due to design and cost efficiency.
4. In wet pipe systems, where is water maintained?
A. Only in the riser
B. In the mains and branches
C. In the entire system piping up to sprinkler heads
D. Only in the branches
Rationale: A wet pipe system holds water throughout all piping ready
for immediate discharge upon activation.
5. What does the term “coverage area” refer to for a sprinkler head?
A. Distance between risers
B. Distance from wall to wall
C. The maximum area a sprinkler is rated to protect
D. Total building footprint
Rationale: Coverage area is the maximum floor area that an
individual sprinkler is designed to cover effectively.
6. What type of system uses open nozzles and a separate fire detection
system?
A. Wet pipe
B. Dry pipe
C. Deluge
D. Preaction
, Rationale: Deluge systems have open nozzles and rely on a separate
detection system to open valves.
7. Which component prevents backflow into the potable water supply?
A. Check valve
B. Control valve
C. Backflow preventer
D. Pressure gauge
Rationale: A backflow preventer stops contaminated water from
reversing into the clean water supply.
8. What is the minimum temperature rating for sprinklers in unheated
storage areas?
A. 100°F
B. 155°F
C. 175°F
D. 325°F
Rationale: Higher temperature-rated sprinklers are necessary in
unheated spaces to avoid false activation due to cold temperatures.
9. Which system type requires air in the piping to hold the dry valve
closed?
A. Wet pipe
B. Dry pipe
C. Deluge
D. Preaction
Rationale: Dry pipe systems use pressurized air to keep the valve
closed until a sprinkler opens.
10. What is an ESFR sprinkler designed to do?
A. Provide ceiling-only coverage
B. Control smoke
C. Suppress high-challenge fires in storage applications
