system?
A. Provide water for domestic plumbing
B. Detect smoke only
C. Control or suppress a developing fire
D. Ventilate the building
Rationale: Sprinkler systems are designed primarily to control
or suppress fires and limit fire growth until occupants can
escape and/or firefighters arrive.
Correct answer: C. Control or suppress a developing fire
2. Which NFPA standard is primarily associated with the
installation of automatic sprinkler systems?
A. NFPA 10
B. NFPA 13
C. NFPA 20
D. NFPA 72
Rationale: NFPA 13 provides the principal requirements for the
installation of sprinkler systems.
Correct answer: B. NFPA 13
3. What is the primary function of a sprinkler head?
,A. Detect carbon monoxide
B. Start the fire pump manually
C. Discharge water when its operating element activates
D. Drain the entire system
Rationale: An automatic sprinkler activates when its heat-
responsive element reaches its operating temperature.
Correct answer: C. Discharge water when its operating
element activates
4. What normally activates an individual standard automatic
sprinkler?
A. Smoke
B. Flame
C. Heat
D. Carbon monoxide
Rationale: Automatic sprinklers are generally heat activated
rather than smoke activated.
Correct answer: C. Heat
5. In a wet-pipe sprinkler system, the piping normally
contains:
A. Air only
B. Nitrogen only
C. Water under pressure
D. Carbon dioxide
Rationale: Wet systems maintain water throughout the
sprinkler piping, allowing rapid water discharge when a
,sprinkler operates.
Correct answer: C. Water under pressure
6. What type of sprinkler system uses air or nitrogen in the
piping under normal conditions?
A. Wet pipe
B. Dry pipe
C. Deluge
D. Standpipe
Rationale: Dry-pipe systems use pressurized air or nitrogen to
hold water behind a dry-pipe valve.
Correct answer: B. Dry pipe
7. What is a major advantage of a wet-pipe system?
A. It requires no water supply
B. It operates only manually
C. Water is immediately available at the sprinklers
D. It cannot freeze
Rationale: Water is already present in the distribution piping,
providing rapid water delivery after sprinkler activation.
Correct answer: C. Water is immediately available at the
sprinklers
8. Which sprinkler system is generally suitable for areas
subject to freezing where ordinary wet piping would be
exposed to freezing temperatures?
, A. Wet pipe
B. Dry pipe
C. Deluge
D. Open-nozzle wet system
Rationale: Dry-pipe systems keep water out of piping in
normally freezing areas.
Correct answer: B. Dry pipe
9. What distinguishes a deluge system from a conventional
wet-pipe system?
A. It has no water supply
B. Open sprinklers or nozzles are used and water is released
through the system when the valve operates
C. It uses only compressed air
D. It cannot be manually activated
Rationale: Deluge systems use open discharge devices and a
valve arrangement that permits water to flow through all
connected outlets when activated.
Correct answer: B. Open sprinklers or nozzles are used and
water is released through the system when the valve operates
10. What is a preaction system designed to reduce?
A. Pipe diameter
B. Water pressure
C. The possibility of accidental water discharge
D. Fire pump capacity
