1. What is the primary purpose of an automatic sprinkler
system?
A. To provide domestic water
B. To detect smoke only
C. To control or suppress a developing fire
D. To ventilate a building
Answer: C. To control or suppress a developing fire
Rationale: Automatic sprinklers discharge water when exposed
to sufficient heat and are designed to control or suppress fires.
2. Which NFPA standard is primarily associated with the
installation of automatic sprinkler systems?
A. NFPA 13
B. NFPA 70
C. NFPA 72
D. NFPA 101
,Answer: A. NFPA 13
Rationale: NFPA 13 establishes requirements for the design and
installation of automatic sprinkler systems.
3. What activates a typical sprinkler head?
A. Smoke
B. Heat
C. Carbon monoxide
D. Manual alarm signal
Answer: B. Heat
Rationale: A standard automatic sprinkler operates when its
heat-sensitive element reaches its rated activation
temperature.
4. What is the purpose of a sprinkler's heat-sensitive element?
A. To measure water pressure
B. To prevent water from entering the piping
C. To release the sprinkler when heated
D. To test the fire pump
Answer: C. To release the sprinkler when heated
Rationale: The heat-sensitive element holds the sprinkler
closed until the designated temperature is reached.
,5. Which component normally controls water entering a
sprinkler system?
A. Main control valve
B. Drain fitting
C. Inspector's test valve
D. Sprinkler deflector
Answer: A. Main control valve
Rationale: The main control valve controls the water supply to
the sprinkler system.
6. Why should a sprinkler control valve normally remain
open?
A. To increase building temperature
B. To maintain the water supply available for fire protection
C. To drain the system
D. To prevent alarms from operating
Answer: B. To maintain the water supply available for fire
protection
Rationale: A closed control valve can prevent water from
reaching sprinklers during a fire.
7. What is the primary purpose of an alarm valve or waterflow
alarm arrangement?
, A. To regulate building temperature
B. To signal water movement caused by sprinkler operation
C. To remove air from the system
D. To measure pipe thickness
Answer: B. To signal water movement caused by sprinkler
operation
Rationale: Waterflow caused by sprinkler operation can
activate an alarm indicating a possible fire.
8. What is the purpose of an inspector's test connection?
A. To simulate operation of a sprinkler
B. To replace the fire pump
C. To permanently drain the building
D. To increase pipe diameter
Answer: A. To simulate operation of a sprinkler
Rationale: The inspector's test connection allows waterflow
and alarm functions to be tested without opening an actual
sprinkler.
9. Which sprinkler system type normally contains pressurized
water in the piping?
A. Dry-pipe system
B. Wet-pipe system
