automatically, preventing fire spread and property damage.
2. Which standard governs the installation of automatic sprinkler
systems?
A. NFPA 10
B. NFPA 13
C. NFPA 72
D. NFPA 25
Rationale:
NFPA 13 provides comprehensive requirements for the design and
installation of automatic sprinkler systems.
3. What type of sprinkler head activates individually when exposed to
heat?
A. Deluge sprinkler
B. Pre-action sprinkler
, C. Standard upright or pendent sprinkler
D. Foam sprinkler
Rationale:
Standard sprinklers have a heat-sensitive element that activates only when
the temperature around that specific head reaches a set point.
4. Which of the following sprinkler systems is typically dry until
activated?
A. Wet pipe system
B. Dry pipe system
C. Deluge system
D. Pre-action system
Rationale:
Dry pipe systems are filled with pressurized air or nitrogen and only release

environments.
5. What is the minimum water pressure required at a sprinkler head for
effective operation?
A. 10 psi
B. 20 psi
C. 7 psi
D. 15 psi
Rationale:
NFPA 13 specifies a minimum pressure of 7 psi at the sprinkler head to
ensure proper water distribution.
6. What device prevents backflow in a sprinkler system?
A. Check valve

A. Ordinary hazard
B. High hazard
C. Areas with sensitive equipment
