1. What is the primary purpose of a fire sprinkler system?
A. To detect smoke
B. To extinguish all fires instantly
C. To control or suppress fire growth
D. To ventilate smoke from a building
Answer: C
Rationale: Fire sprinkler systems are designed primarily to control or
suppress fire growth, not necessarily extinguish every fire completely.
They limit heat and flame spread until firefighters arrive.
2. Which component automatically activates a sprinkler head?
A. Smoke detector
B. Heat-sensitive element
,C. Manual pull station
D. Fire alarm panel
Answer: B
Rationale: Sprinkler heads activate when a heat-sensitive element (such
as a glass bulb or fusible link) reaches its rated temperature and breaks
or melts.
3. What is the standard color coding for sprinkler head temperature
rating?
A. Blue for low temperature
B. Red for ordinary temperature
C. Orange for high temperature
D. Yellow for extra-high temperature
Answer: B
Rationale: Red glass bulbs typically represent ordinary temperature
ratings (around 155°F). Color codes indicate activation temperature
ranges.
4. What is the purpose of a fire department connection (FDC)?
A. To drain the sprinkler system
,B. To allow firefighters to pump water into the system
C. To detect water flow
D. To shut down the alarm system
Answer: B
Rationale: The FDC allows fire department pumpers to supplement or
supply water to the sprinkler or standpipe system.
5. A wet pipe sprinkler system contains what type of piping?
A. Air under pressure
B. Nitrogen only
C. Water at all times
D. Foam concentrate
Answer: C
Rationale: Wet pipe systems are filled with water at all times, making
them the most common and fastest to respond.
6. Which system is best suited for freezing environments?
A. Wet pipe system
B. Dry pipe system
, C. Deluge system
D. Pre-action system
Answer: B
Rationale: Dry pipe systems use pressurized air or nitrogen in the pipes
and water is released only when a valve opens, preventing freezing.
7. What triggers a dry pipe valve to open?
A. Smoke detection
B. Loss of air pressure
C. Manual activation only
D. Electrical signal
Answer: B
Rationale: When air pressure drops due to a sprinkler opening, the dry
pipe valve allows water into the system.
8. A deluge system is characterized by:
A. Closed sprinkler heads
B. Water-filled pipes at all times
C. Open sprinkler heads
D. Air-filled piping only
