1. A wet-pipe sprinkler system is most appropriate for which of the
following environments?
A. Unheated warehouse
B. Residential home
C. Industrial freezer
D. Museum storage room
B. Residential home
Wet-pipe systems are suitable for areas where freezing is not a
concern because water is constantly in the pipes, allowing immediate
discharge in case of fire.
2. The primary function of a dry-pipe valve in a sprinkler system is to:
A. Allow antifreeze solution to circulate
B. Prevent water from entering until needed
C. Regulate system water pressure continuously
D. Control the flow of fire pump suction
B. Prevent water from entering until needed
, Dry-pipe valves keep water out of the piping in areas subject to
freezing, releasing water only when a sprinkler activates.
3. Which NFPA standard governs the installation of underground fire
sprinkler mains?
A. NFPA 13
B. NFPA 14
C. NFPA 24
D. NFPA 25
C. NFPA 24
NFPA 24 specifically addresses the installation of private fire service
mains and their appurtenances.
4. In a deluge sprinkler system, the sprinklers are:
A. Closed with individual thermal elements
B. Open at all times
C. Filled with antifreeze
D. Designed only for residential use
B. Open at all times
Deluge systems have open sprinklers and are activated by a separate
detection system, delivering large volumes of water rapidly.
5. A common method for protecting dry-pipe systems in cold
environments is:
A. Installing antifreeze loops
B. Using electric heat tracing
C. Insulating the piping
D. All of the above
D. All of the above
Antifreeze, heat tracing, and insulation are all techniques to prevent
freezing in dry-pipe systems.
, 6. When performing hydrostatic testing on a sprinkler system, the
pressure must be maintained for:
A. 5 minutes
B. 30 minutes
C. 2 hours
D. 24 hours
B. 30 minutes
NFPA standards require hydrostatic tests to hold the test pressure for
at least 30 minutes to check for leaks.
7. The minimum allowable spacing between standard pendent sprinklers
in a storage occupancy is typically:
A. 12 feet
B. 15 feet
C. 20 feet
D. 25 feet
B. 15 feet
NFPA 13 specifies maximum spacing for sprinklers in ordinary hazard
storage to ensure adequate coverage.
8. Which type of fire pump is typically preferred for high-rise buildings?
A. Centrifugal
B. Vertical turbine
C. Positive displacement
D. Rotary vane
B. Vertical turbine
Vertical turbine pumps are preferred in high-rise buildings due to
their ability to lift water from deep sumps and maintain high
pressure.
9. A pre-action sprinkler system requires:
A. Immediate water flow when a sprinkler opens
