1. What is the primary purpose of an automatic sprinkler system
installed in a building?
A. To provide a permanent source of potable water
B. To detect and control or suppress a developing fire by automatically
discharging water through operating sprinkler heads
C. To replace all required fire alarm notification appliances
D. To provide normal domestic-water pressure
Answer: B
An automatic sprinkler system is designed to respond automatically to
heat from a developing fire and discharge water through operating
sprinklers to control or suppress the fire, thereby limiting fire growth and
protecting occupants and property.
2. Which component normally initiates water discharge from an
individual automatic sprinkler?
,A. Fire alarm control panel
B. Sprinkler head whose heat-responsive element operates at its rated
temperature
C. Manual fire alarm box
D. Supervisory switch
Answer: B
A standard automatic sprinkler is individually operated by its heat-
responsive element. When the element reaches its operating temperature,
the sprinkler opens and permits water to discharge over the protected
area.
3. What is the primary function of the sprinkler deflector?
A. To regulate the building's water pressure
B. To distribute discharged water in the required spray pattern over the
protected area
C. To detect smoke
D. To supervise the control valve
Answer: B
The deflector shapes and distributes water discharged from the sprinkler
orifice into the pattern for which the sprinkler is listed. Proper orientation
and clearance are therefore essential to performance.
4. Why is sprinkler orientation important during installation?
A. The sprinkler's listed discharge pattern and thermal response depend on
correct installation orientation
B. Orientation affects only the appearance of the piping
C. Any sprinkler can be installed in any orientation
D. Orientation determines the building's occupancy classification
Answer: A
,Sprinklers are listed for specific orientations and installation
arrangements. Installing a sprinkler contrary to its listing can alter its
water-distribution pattern or thermal response and compromise
protection.
5. What is the primary purpose of a sprinkler system control valve?
A. To detect smoke
B. To control the water supply to a sprinkler system or portion of the system
C. To produce the sprinkler discharge pattern
D. To operate the fire alarm notification appliances
Answer: B
A control valve regulates the water supply to the sprinkler system or a
designated portion of it. Because a closed valve can disable protection,
required control valves are generally supervised or otherwise secured in
their proper position.
6. Why must a sprinkler control valve normally remain in its required
open position?
A. Closing the valve can prevent water from reaching sprinklers during a fire
B. Closing the valve increases sprinkler sensitivity
C. Closing the valve improves water distribution
D. The valve position affects only maintenance records
Answer: A
A closed control valve can interrupt the water supply to the protected area
and render the sprinkler system ineffective. Proper valve position is
therefore a critical life-safety condition.
7. What is the purpose of a valve supervisory switch?
A. To monitor the position of a supervised control valve and transmit an
abnormal condition when the valve moves from its required position
, B. To open sprinkler heads automatically
C. To measure water temperature
D. To replace the waterflow alarm
Answer: A
A valve supervisory switch monitors the position of a control valve. When
the valve is moved from its required position, the switch can transmit a
supervisory signal to the fire alarm system.
8. What is the principal function of a sprinkler waterflow alarm device?
A. To detect qualifying movement of water in the sprinkler system and
initiate the required alarm signal
B. To regulate the water supply pressure
C. To close the sprinkler control valve
D. To detect smoke in occupied spaces
Answer: A
A waterflow device responds to qualifying water movement associated
with sprinkler operation and initiates the required alarm or signaling
function through the connected fire alarm system or other approved
arrangement.
9. Which device is commonly used to test the operation of a waterflow
alarm without flowing water through an operating sprinkler?
A. Inspector's test connection
B. Main drain valve
C. Pressure-reducing valve
D. Backflow preventer
Answer: A
