1. What is the primary purpose of inspecting a fire protection system?
A. To increase insurance premiums
B. To verify that the system remains capable of performing its intended function
C. To replace all system components annually
D. To eliminate the need for maintenance
Answer: To verify that the system remains capable of performing its intended

Rationale: Inspection is intended to identify conditions that could impair the
operation or reliability of a fire protection system.
, 2. Which Delaware agency has primary responsibility for licensing fire
protection companies and individuals?
A. Delaware Department of Transportation
B. Delaware State Fire Marshal's Office
C. Delaware Department of Agriculture
D. Delaware Department of Labor
Answer: Delaware State Fire Marshal's Office
Rationale: The Office of the State Fire Marshal licenses companies and

systems in Delaware.
3. Which organization publishes many of the nationally recognized fire
protection standards used in inspection work?
A. OSHA
B. NFPA
C. EPA
D. ANSI only
Answer: NFPA
Rationale: The National Fire Protection Association develops numerous fire
protection codes and standards, including standards governing inspection and
testing.
4. What is the difference between inspection and testing?
A. Inspection is visual or physical examination, while testing evaluates operation
or performance
B. Testing is always visual and inspection is always electrical
C. They are exactly the same activity
D. Inspection is performed only after a fire
Answer: Inspection is visual or physical examination, while testing evaluates
operation or performance
,Rationale: Inspection identifies condition, while testing determines whether
equipment or system functions as intended.
5. What should an inspector do before beginning an inspection?
A. Immediately operate every valve
B. Review available system information and identify the scope of work
C. Remove alarm batteries
D. Drain the sprinkler system
Answer: Review available system information and identify the scope of work
Rationale: Understanding the system, previous deficiencies, records, and
inspection scope helps the inspector perform a complete and safe inspection.
6. What is a major concern when a control valve is found partially closed?
A. Reduced system water pressure and impaired sprinkler operation
B. Increased lighting
C. Improved alarm operation
D. Increased battery life
Answer: Reduced system water pressure and impaired sprinkler operation
Rationale: A partially closed water supply control valve can restrict water flow
and seriously impair a sprinkler or standpipe system.
7. What is the purpose of a waterflow alarm?
A. To prevent water from entering the system
B. To indicate movement of water through the sprinkler system
C. To regulate building temperature
D. To test emergency lighting
Answer: To indicate movement of water through the sprinkler system
Rationale: Waterflow devices respond to sustained water movement associated
with sprinkler operation or another water-demand condition.
, 8. What component typically detects a sprinkler system waterflow condition?
A. Waterflow switch
B. Smoke detector
C. Heat detector only
D. Door contact
Answer: Waterflow switch
Rationale: Waterflow switches are designed to detect water movement and
initiate the appropriate alarm signal.
9. What is the primary function of a sprinkler head?
A. Detect smoke only
B. Automatically discharge water when its operating element reaches its rated
temperature
C. Supply electrical power
D. Monitor fire alarm batteries
Answer: Automatically discharge water when its operating element reaches its
rated temperature
Rationale: Automatic sprinklers are designed to operate individually when
exposed to sufficient heat.
10.Why should sprinkler heads be kept free of obstruction?
A. Obstructions can interfere with the intended water distribution pattern
B. Obstructions increase electrical conductivity
C. Obstructions make the alarm louder
D. Obstructions improve water pressure
Answer: Obstructions can interfere with the intended water distribution pattern
Rationale: Storage, construction, paint, or other obstructions can prevent proper
sprinkler discharge from reaching the protected area.
