1. A sprinkler system is being installed in a commercial building. Before
beginning work, the contractor should first verify that the installation
conforms to:
A. The manufacturer's preference only
B. The approved construction documents and applicable NYC requirements
C. The building owner's verbal instructions
D. The pipe supplier's catalog
Answer: B. The approved construction documents and applicable NYC
requirements
The installation must follow the approved plans, applicable codes, and
required standards.
2. During installation, a pipe is found to conflict with a structural beam
shown differently in the field than on the approved plans. What is the
proper action?
A. Cut the beam to make room
B. Relocate the beam
C. Stop and resolve the conflict through the proper design/approval process
D. Install the pipe without regard to the beam
Answer: C. Stop and resolve the conflict through the proper design/approval
process
Field conditions that differ from approved documents must be properly
resolved rather than handled by unauthorized modifications.
3. A sprinkler pipe is supported from a ceiling assembly. The most
important consideration when selecting the support arrangement is that
it:
A. Is decorative
B. Can support the piping system and withstand expected loads
,C. Is attached only to ceiling tile
D. Uses the smallest available hanger
Answer: B. Can support the piping system and withstand expected loads
Sprinkler piping supports must provide adequate structural support and
maintain the required stability of the system.
4. A sprinkler branch line is being installed. Which condition is most likely
to create an obstruction problem?
A. Correct pipe alignment
B. A sprinkler located beneath an obstruction that interferes with its discharge
pattern
C. Proper pipe supports
D. Correct fitting installation
Answer: B. A sprinkler located beneath an obstruction that interferes with its
discharge pattern
Sprinkler discharge must not be improperly obstructed because obstruction
can prevent the required distribution of water.
5. Before concealed sprinkler piping is covered by construction, the
contractor should ensure that:
A. The system has been inspected as required and necessary testing has been
completed
B. The ceiling is painted
C. All valves are removed
D. The water supply is permanently disconnected
Answer: A. The system has been inspected as required and necessary testing
has been completed
Required inspections and tests must occur before concealed portions become
inaccessible.
6. A control valve serving a sprinkler system is installed in a location where
it cannot be easily reached. What is the principal problem?
A. The pipe is too short
B. The valve cannot be readily operated during an emergency
,C. The valve is too large
D. The sprinkler heads will discharge too quickly
Answer: B. The valve cannot be readily operated during an emergency
Fire protection control valves must be accessible for operation, inspection, and
maintenance.
7. A contractor discovers that a sprinkler control valve has been left
partially closed. What should be done?
A. Leave it as found
B. Fully open the valve as required and verify its proper supervisory condition
C. Remove the valve
D. Paint the valve
Answer: B. Fully open the valve as required and verify its proper supervisory
condition
Control valves must be maintained in their required operating position so the
system remains capable of supplying water.
8. A pipe joint begins leaking during a pressure test. What is the correct
response?
A. Increase the test pressure
B. Ignore the leak if it is small
C. Correct the defective joint and repeat the required test
D. Cover the joint with insulation
Answer: C. Correct the defective joint and repeat the required test
A failed joint must be repaired and the system retested to verify integrity.
9. Which tool is most appropriate for checking whether a threaded pipe
connection has been properly tightened?
A. Level only
B. Appropriate pipe wrench and inspection of the completed connection
C. Hammer only
D. Tape measure only
, Answer: B. Appropriate pipe wrench and inspection of the completed
connection
Threaded joints require proper assembly using suitable tools without damaging
the fittings or pipe.
10.A grooved sprinkler piping system is being assembled. Before coupling
two pipe sections, the contractor should verify that:
A. The pipe ends and grooves are clean and properly prepared
B. The gasket is removed
C. The coupling bolts are missing
D. The pipe ends are intentionally damaged
Answer: A. The pipe ends and grooves are clean and properly prepared
Proper preparation of grooved components is essential for a reliable
mechanical joint.
11.A sprinkler system contains a backflow prevention assembly. Its purpose
is primarily to:
A. Increase building temperature
B. Prevent unwanted reverse flow into the potable water supply
C. Reduce sprinkler coverage
D. Drain the roof
Answer: B. Prevent unwanted reverse flow into the potable water supply
Backflow protection prevents contaminated or nonpotable water from flowing
back into the potable water system.
12.A sprinkler system requires a drain connection. The drain should be
arranged so that:
A. Water cannot be discharged
B. The system can be properly drained and the discharge handled safely
C. The valve is permanently sealed
D. The drain terminates inside electrical equipment
Answer: B. The system can be properly drained and the discharge handled
safely
