ALABAMA FIRE SPRINKLER FITTER EXAMINATION
COMPLETE QUESTIONS AND DETAILED SOLUTIONS
LATEST UPDATE THIS YEAR JUST RELEASED
1.
When installing a wet-pipe sprinkler system, which component
primarily controls the flow of water into the system piping?
A. Inspector's test connection
B. Alarm check valve
C. Main drain
D. Fire department connection
Answer: B. Alarm check valve
Rationale: The alarm check valve permits water to enter the sprinkler
system while preventing unwanted reverse flow and initiating
waterflow alarm functions when sprinklers operate.
2.
Why must sprinkler pipe be properly supported and secured
throughout an installed fire sprinkler system?
A. To improve water temperature
B. To reduce pipe movement and maintain system integrity
C. To increase sprinkler temperature ratings
D. To eliminate the need for hangers
,Answer: B. To reduce pipe movement and maintain system integrity
Rationale: Proper supports prevent excessive movement, stress,
sagging, and mechanical damage that could compromise piping
connections or sprinkler performance during operation.
3.
What is the primary purpose of an inspector's test connection installed
on a sprinkler system?
A. To supply permanent building water
B. To simulate operation of a single sprinkler
C. To drain underground piping
D. To regulate system pressure
Answer: B. To simulate operation of a single sprinkler
Rationale: The inspector's test connection allows technicians to
simulate sprinkler waterflow and verify alarms, valves, and associated
monitoring equipment without activating an actual sprinkler.
4.
Which type of sprinkler system normally contains pressurized air or
nitrogen above water in the system piping?
A. Wet pipe
B. Dry pipe
C. Deluge
D. Standpipe
,Answer: B. Dry pipe
Rationale: Dry-pipe systems use pressurized air or nitrogen to hold
water behind a dry-pipe valve until system operation releases the valve.
5.
Why is compressed air or nitrogen used in dry-pipe sprinkler systems
before the system operates?
A. To cool sprinkler piping
B. To prevent water from entering piping prematurely
C. To increase water temperature
D. To lubricate sprinkler fittings
Answer: B. To prevent water from entering piping prematurely
Rationale: Pressurized gas maintains the dry system condition and
keeps water on the supply side of the dry-pipe valve until activation
occurs.
6.
Which sprinkler system is designed to discharge water simultaneously
through all open sprinklers when the system operates?
A. Wet pipe
B. Dry pipe
C. Deluge
D. Preaction
, Answer: C. Deluge
Rationale: Deluge systems have open sprinklers and rely on a deluge
valve, allowing water to flow through all connected discharge outlets
simultaneously.
7.
What is the primary function of a fire department connection on a
sprinkler installation?
A. To drain system water
B. To allow firefighters to supplement system water supply
C. To test individual sprinklers
D. To reduce hydraulic pressure
Answer: B. To allow firefighters to supplement system water supply
Rationale: The fire department connection provides firefighters with an
external connection for supplying additional water to the sprinkler or
standpipe system.
8.
When grooved sprinkler pipe is installed, why must the groove
dimensions and coupling installation be correct?
A. To change sprinkler temperature ratings
B. To ensure a reliable mechanical pipe connection
C. To eliminate system testing
D. To increase water density automatically
