Massachusetts Sprinkler Fitter Licensing
Exam Questions And Correct Answers
(Verified Answers) Plus Rationales
1. A wet-pipe sprinkler system is best described as one that:
A. Is filled with air until activated
B. Contains water in the piping at all times
C. Requires a heat exchanger for operation
D. Uses dry chemical agents for fire suppression
A wet-pipe sprinkler system maintains water in its piping at all times
to provide the fastest discharge when a sprinkler head activates.
2. The purpose of a dry-pipe valve in a sprinkler system is to:
A. Regulate water pressure for high-rise installations
B. Filter debris entering the system
C. Separate water from pressurized air to prevent freeze in piping
D. Increase flow rate to hose valves
A dry-pipe valve isolates the water and allows the piping to be filled
with air to prevent freezing, releasing water only upon activation.
3. NFPA standards require that sprinkler system standby power must be
provided for:
A. All residential systems only
B. Systems in Type III construction
C. Fire pumps where automatic starting is required
D. Ordinary hazard systems without pumps
Standby power ensures that required fire pumps automatically start
during power loss to maintain system functionality.
4. The minimum required pressure for a fire department connection
(FDC) is typically measured at:
A. The system riser
, B. The highest sprinkler head
C. The base of the fire pump suction
D. The outlet of the jockey pump
Minimum FDC pressure ensures adequate flow into the system,
typically referenced at the pump suction to guarantee delivery.
5. When installing a sprinkler head near structural steel, the fitter must:
A. Place it at least 6 inches away
B. Avoid mounting within 6 inches of objects that could impede spray
C. Install it directly adjacent for support
D. Use the nearest branch line available
Sprinkler coverage requires clearance; obstructions like steel should
not be within 6 inches to allow proper spray patterns.
6. A pendent sprinkler head is designed to:
A. Spray horizontally along the ceiling
B. Be installed in walls only
C. Hang downward from the branch line
D. Direct water upward
Pendent sprinklers hang down and discharge water in a pattern
suitable for open areas.
7. The primary function of a check valve in a sprinkler system is to:
A. Reduce supply pressure
B. Filter incoming water
C. Prevent backflow of water
D. Increase hydrant pressure
Check valves allow flow in only one direction, ensuring water does
not return to source.
8. A fire pump controller must be located:
A. Outside the pump room
B. Near the fire pump driver
C. At the system riser
D. In the main electrical panel
Controller proximity to the driver ensures immediate control and
indicator visibility for the fire pump.
9. The minimum number of sprinkler heads between the alarm check
valve and the inspector’s test connection is:
, A. One
B. Two
C. Three
D. Four
Two heads are required to ensure that the inspector’s test simulates
system flow beyond just one head.
10. A backflow preventer in a sprinkler system is installed to:
A. Increase flow rate
B. Reduce system pressure
C. Protect potable water supply from contamination
D. Divert water to auxiliary services
Protecting potable water from contamination by sprinkler system
water is the main purpose of a backflow preventer.
11. An antifreeze loop in a sprinkler system must be:
A. Less than 5 feet long
B. Approved and tested for concentration and temperature
C. Filled with any glycol solution available
D. Installed at every branch line
Antifreeze systems require approved solutions and testing to ensure
proper freeze protection without compromising operation.
12. Which component of a fire sprinkler system maintains system
pressure between the pump start and fire department supply?
A. Alarm valve
B. Backflow preventer
C. Jockey pump
D. Suction strainer
A jockey pump maintains normal system pressure by compensating
for minor leaks and pressure fluctuations.
13. The minimum distance between a sprinkler deflector and the
ceiling in a standard installation is:
A. ½ inch
B. 1 inch
C. 3 inches
D. 6 inches
