1. What is the primary purpose of a fire sprinkler system?
A. Increase building aesthetics
B. Suppress or control fires
C. Ventilate smoke
D. Detect gas leaks
Fire sprinkler systems are designed to suppress or control fires
automatically.
2. NFPA 13 is the standard for:
A. Fire alarm systems
B. Fire extinguisher installation
C. Installation of sprinkler systems
D. Emergency lighting
NFPA 13 specifically governs the design and installation of
sprinkler systems.
3. The minimum spacing between sprinkler heads is determined by:
A. Ceiling color
B. Type of sprinkler and coverage area
C. Room occupancy
D. Building height
, Sprinkler spacing depends on design criteria such as type of
sprinkler, hazard classification, and coverage.
4. Which type of sprinkler is commonly used for residential
applications?
A. Dry pendant
B. Quick-response sprinkler
C. Pre-action sprinkler
D. Deluge sprinkler
Quick-response sprinklers are widely used in residential areas for
fast activation.
5. A wet pipe sprinkler system:
A. Requires heating
B. Contains water in the pipes at all times
C. Uses air pressure
D. Activates manually only
Wet pipe systems maintain water in the pipes and discharge
automatically when sprinklers operate.
6. What is the main advantage of a dry pipe sprinkler system?
A. Lower cost
B. Faster response
C. Prevents freezing in unheated areas
D. Requires less maintenance
Dry pipe systems keep air in the pipes, preventing freezing in cold
areas.
7. A pre-action sprinkler system requires:
A. Manual activation only
B. A separate detection system to activate the water
C. Constant water in pipes
D. Heat to activate
, Pre-action systems are used where accidental discharge must be
avoided; they require detection before water flows.
8. Which class of fire is best suppressed by water?
A. Class A
B. Class B
C. Class C
D. Class D
Class A fires (ordinary combustibles like wood, paper) are
effectively suppressed with water.
9. Fire pump installation is required when:
A. There is no water supply
B. Sprinkler heads are too high
C. Required pressure and flow cannot be maintained by the
water supply
D. Only in residential buildings
Fire pumps boost water pressure to meet sprinkler and hose
system requirements.
10. The purpose of a check valve in a fire sprinkler system is to:
A. Increase flow
B. Prevent backflow
C. Reduce water pressure
D. Alert the fire department
Check valves prevent water from flowing backward into the supply
system.
11. The main function of a deluge sprinkler system is to:
A. Protect only electrical equipment
B. Deliver large amounts of water quickly over a wide area
