1. The primary purpose of a wet-pipe sprinkler system is to:
A. provide a supply of water for occupant use
B. detect fires and sound an alarm
C. deliver water automatically to a fire area
D. prevent steam explosions
Answer: C. deliver water automatically to a fire area
Explanation: Wet-pipe systems maintain water in the piping under
pressure and activate automatically at the sprinkler nearest the fire,
delivering water to control or suppress the fire. The system's primary
function is fire suppression, not detection, occupant use, or explosion
prevention.
2. Which NFPA standard governs the installation of sprinkler systems?
,2|Page
A. NFPA 70
B. NFPA 101
C. NFPA 13
D. NFPA 25
Answer: C. NFPA 13
Explanation: NFPA 13 is the Standard for the Installation of Sprinkler
Systems, covering design and layout requirements. NFPA 25 covers
inspection, testing, and maintenance. NFPA 70 is the National Electrical
Code. NFPA 101 is the Life Safety Code.
3. In a dry-pipe sprinkler system, the purpose of the dry pipe valve is to:
A. heat the piping to prevent freezing
B. release water into the supply main
C. seal the water supply until a sprinkler operates
D. maintain constant water pressure in the system
Answer: C. seal the water supply until a sprinkler operates
Explanation: The dry-pipe valve holds water back at the supply side.
When a sprinkler opens, the valve trips and allows water to flow into
the piping, which is necessary in systems installed in areas subject to
freezing.

4. The function of a deluge valve is to:
A. restrict flow to sprinklers
B. allow large-volume water flow when activated by a detection system
C. slow down water hammer
D. control system pressures during testing
Answer: B. allow large-volume water flow when activated by a
detection system
Explanation: Deluge systems have open sprinklers and use a deluge
valve controlled by a detection system to rapidly deliver large volumes
of water over a protected area. All sprinklers discharge simultaneously
when the system is activated.
5. What is the typical pressure source for fire pump installations?
A. air compressor
B. household well pump
C. electric or diesel driven fire pump
D. gravity only
Answer: C. electric or diesel driven fire pump
, 4|Page
Explanation: Fire pumps are commonly driven by electric motor or diesel
engine to boost water supply and pressure for the fire protection
system. These are the standard prime movers for fire pump
installations.
6. Sprinkler response classification includes:
A. standard, quick, and residential
B. stainless steel only
C. non-response
D. industrial response
Answer: A. standard, quick, and residential
Explanation: Sprinklers are classified by their response characteristics.
Quick-response sprinklers have a Response Time Index (RTI) of 50 or
less. Standard-response sprinklers have an RTI of 80 or more.
Residential sprinklers are a type of quick-response sprinkler with specific
performance criteria.
7. The K-factor of a sprinkler is used to:
A. indicate the temperature rating
B. calculate the flow rate from a sprinkler at a given pressure
C. define the thread type
D. determine the color of the sprinkler frame
