1. What is the primary purpose of an automatic fire sprinkler
system?
A. To provide domestic water for occupants
B. To cool electrical equipment
C. To control or suppress a developing fire
D. To replace portable fire extinguishers
Rationale: Automatic sprinklers are designed to detect heat and
discharge water over the fire area. Their primary purpose is to control
or suppress fire growth, limit property damage, and help protect life
until the fire is extinguished or emergency personnel arrive.
2. Which component of a sprinkler system is designed to open
automatically when exposed to a predetermined temperature?
,A. Alarm check valve
B. Sprinkler head
C. Fire department connection
D. Main control valve
Rationale: A sprinkler head contains a heat-sensitive operating
element, such as a fusible link or glass bulb. When the surrounding
temperature reaches its rated activation temperature, the element
releases and allows water to discharge.
3. What is the main function of a fire department connection (FDC)?
A. To drain the sprinkler system
B. To regulate domestic water pressure
C. To allow the fire department to supplement the sprinkler system
with water
D. To activate individual sprinkler heads
Rationale: The FDC provides firefighters with a connection through
which they can pump additional water into the sprinkler system. This
can supplement the available water supply during a fire.
4. What type of sprinkler system contains water in the piping above
the closed sprinkler heads under normal conditions?
,A. Dry-pipe system
B. Deluge system
C. Preaction system
D. Wet-pipe system
Rationale: A wet-pipe system is filled with pressurized water during
normal operation. When a sprinkler activates from heat, water
immediately flows from that sprinkler.
5. Which sprinkler system is generally used where piping may be
exposed to freezing temperatures?
A. Wet-pipe system
B. Dry-pipe system
C. Domestic water system
D. Wet standpipe system
Rationale: Dry-pipe systems contain pressurized air or nitrogen
instead of water in portions of the piping subject to freezing. When a
sprinkler opens, the dry-pipe valve operates and allows water to enter
the piping.
6. In a dry-pipe sprinkler system, what normally holds the dry-pipe
valve closed?
, A. Gravity
B. Electrical current
C. Air or nitrogen pressure
D. Domestic water pressure alone
Rationale: A dry-pipe valve uses the differential between system air
pressure and water pressure to remain closed. When a sprinkler
operates, the air pressure drops, allowing the valve to open and water
to enter the system.
7. What is the primary purpose of a fire sprinkler alarm valve?
A. To increase domestic water pressure
B. To control water flow and provide an alarm indication when water
flows
C. To prevent every sprinkler from opening
D. To drain the fire pump
Rationale: An alarm valve controls the flow of water into a wet-pipe
sprinkler system and can operate mechanical or electrical alarm
devices when sustained water flow occurs.
8. What does a sprinkler's temperature rating indicate?
A. The maximum water pressure allowed in the pipe
B. The minimum ambient temperature of the building
