FDNY S-11 Exam Practice Questions with Correct Answers
1.
What is the primary purpose of a residential sprinkler system?
A. Detect carbon monoxide
B. Control or suppress a developing fire
C. Ventilate smoke
D. Replace fire alarms
Correct Answer: B
Rationale: Residential sprinklers automatically discharge water
when exposed to sufficient heat and are designed to control or
suppress developing fires.
2.
What normally activates an automatic sprinkler?
A. Smoke
B. Heat
C. Sound
D. Light
Correct Answer: B
Rationale: Automatic sprinklers operate when their heat-responsive
element reaches its operating temperature.
3.
When one sprinkler operates, what normally happens to the other
sprinklers?
A. They all immediately open
B. They all close
C. They remain closed unless individually heated
D. They are permanently disabled
Correct Answer: C
Rationale: Each sprinkler operates independently when its own
heat-responsive element reaches its operating condition.
4.
,What is the function of a sprinkler's heat-responsive element?
A. Measure water pressure
B. Release the sprinkler when sufficiently heated
C. Detect smoke
D. Control building electricity
Correct Answer: B
Rationale: The heat-responsive element holds the sprinkler closed
until the specified operating condition is reached.
5.
What does a glass-bulb sprinkler use for activation?
A. A fusible link
B. A heat-sensitive liquid-filled bulb
C. A smoke chamber
D. An electrical relay
Correct Answer: B
Rationale: Glass-bulb sprinklers contain a heat-sensitive liquid that
expands and breaks the bulb at its rated temperature.
6.
What happens when a fusible-link sprinkler reaches its operating
temperature?
A. The link releases
B. The pipe drains
C. The alarm stops
D. The water supply closes
Correct Answer: A
Rationale: Heat causes the fusible link to release the sprinkler
mechanism, allowing water to discharge.
7.
What is the purpose of an escutcheon?
A. Measure pressure
B. Cover the opening around a sprinkler
,C. Operate a valve
D. Detect water flow
Correct Answer: B
Rationale: An escutcheon provides a finished cover around the
opening where a sprinkler penetrates a ceiling or wall.
8.
What does a pressure gauge indicate?
A. Water pressure
B. Room occupancy
C. Smoke concentration
D. Sprinkler temperature rating
Correct Answer: A
Rationale: A pressure gauge indicates pressure at the point where it
is connected.
9.
What is the purpose of a sprinkler control valve?
A. Control water entering the sprinkler system
B. Detect smoke
C. Measure room temperature
D. Operate fire extinguishers
Correct Answer: A
Rationale: The control valve regulates the water supply to the
sprinkler system.
10.
Why should a sprinkler control valve normally remain in its required
open position?
A. To allow water to reach sprinklers
B. To prevent water from entering
C. To reduce alarm volume
D. To increase room temperature
Correct Answer: A
, Rationale: Closing the control valve can prevent water from reaching
sprinklers during a fire.
11.
What is a wet-pipe sprinkler system?
A. Piping normally containing water
B. Piping containing only air
C. Piping containing foam only
D. Piping with no water source
Correct Answer: A
Rationale: A wet-pipe system normally contains water under
pressure throughout the sprinkler piping.
12.
What is the principal concern with water-filled sprinkler piping
exposed to freezing conditions?
A. Water can freeze and damage piping
B. Sprinklers become smoke detectors
C. Water becomes nonconductive
D. Pressure always increases safely
Correct Answer: A
Rationale: Freezing water expands and can damage piping, fittings,
and other components.
13.
What is the purpose of a dry-pipe arrangement in areas subject to
freezing?
A. Keep water out of vulnerable piping until operation
B. Eliminate all sprinklers
C. Increase room temperature
D. Remove the water supply
Correct Answer: A
Rationale: Dry-pipe arrangements can help protect areas where
water-filled piping could freeze.
