1. What is the primary purpose of an automatic fire sprinkler
system?
a. To provide drinking water during emergencies
b. To control or suppress a developing fire
c. To remove smoke from a building
d. To provide water for cleaning
Answer: b. To control or suppress a developing fire
Rationale: Automatic sprinkler systems are designed primarily to
control or suppress fires in their early stages. Sprinklers discharge
water when exposed to sufficient heat, helping limit fire growth,
protect occupants, and reduce property damage.
, 2. Which component of a sprinkler system is designed to open when
exposed to a predetermined temperature?
a. Alarm valve
b. Fire pump
c. Sprinkler head
d. Check valve
Answer: c. Sprinkler head
Rationale: A sprinkler head contains a heat-responsive element that
releases when the surrounding temperature reaches its operating
point. This allows water to discharge at the location of the developing
fire.
3. What is the primary function of a fire department connection
(FDC)?
a. To drain the sprinkler system
b. To allow firefighters to supplement water to the fire protection
system
c. To shut off the building water supply
d. To test smoke detectors
Answer: b. To allow firefighters to supplement water to the fire
protection system
,Rationale: The FDC provides firefighters with an external connection
through which they can pump additional water into a sprinkler or
standpipe system. This supplements the available water supply during
firefighting operations.
4. Which type of sprinkler system normally contains water under
pressure in the piping before a sprinkler operates?
a. Dry-pipe system
b. Preaction system
c. Wet-pipe system
d. Deluge system
Answer: c. Wet-pipe system
Rationale: A wet-pipe sprinkler system contains water in the
distribution piping under normal conditions. When a sprinkler
operates from heat, water immediately discharges from that
sprinkler.
5. Which sprinkler system is commonly used where piping may be
exposed to freezing temperatures?
a. Wet-pipe system
b. Dry-pipe system
, c. Deluge system
d. Wet standpipe only
Answer: b. Dry-pipe system
Rationale: Dry-pipe systems contain pressurized air or nitrogen in the
piping rather than water. When a sprinkler operates, the pressure
changes allow the dry-pipe valve to open and water to enter the
piping.
6. What is the principal purpose of a dry-pipe valve?
a. To regulate building heating
b. To separate the water supply from the normally dry distribution
piping
c. To measure water temperature
d. To remove sediment from the system
Answer: b. To separate the water supply from the normally dry
distribution piping
Rationale: The dry-pipe valve holds back the water supply while the
system piping is maintained with pressurized air or nitrogen. When
the valve trips, water enters the distribution piping.
7. What type of sprinkler system normally uses open sprinklers or
open nozzles?
