Which of the following is the primary purpose of a fire protection system?
A. Reduce water consumption
B. Prevent or minimize fire damage
C. Increase building value
D. Maintain indoor air quality
Rationale: The main goal of fire protection systems is to prevent fire
occurrence or minimize damage and loss from fires.
1. What type of fire extinguisher should be used for electrical fires?
A. Water
B. Foam
C. CO2
D. Wet chemical
Rationale: CO2 extinguishers do not conduct electricity, making
them safe for electrical fires.
2. In a sprinkler system, the main function of the riser is to:
A. Store water
B. Act as a drain
C. Distribute water to sprinkler heads
D. Prevent corrosion
Rationale: The riser carries water from the main supply to the
sprinkler network.
3. Which NFPA standard covers installation of fire alarm systems?
A. NFPA 13
, B. NFPA 25
C. NFPA 72
D. NFPA 101
Rationale: NFPA 72 provides the requirements for fire alarm and
signaling systems.
4. What is the recommended spacing between standard sprinkler heads in
an ordinary hazard area?
A. 6–8 feet
B. 8–10 feet
C. 12–15 feet
D. 18–20 feet
Rationale: NFPA 13 specifies spacing of 12–15 feet for ordinary
hazard areas to ensure adequate coverage.
5. What type of detection device responds to heat rather than smoke?
A. Ionization detector
B. Heat detector
C. Photoelectric detector
D. Flame detector
Rationale: Heat detectors are triggered by high temperatures or rapid
temperature rise.
6. Which component in a fire alarm system is responsible for transmitting
signals to the monitoring center?
A. Notification appliance
B. Control panel
C. Manual pull station
D. Detector
Rationale: The control panel processes signals from detectors and

involving cooking oils and fats.
9. What is the primary purpose of a fire pump in a sprinkler system?
A. Reduce water pressure
B. Purify water
C. Maintain adequate water pressure and flow
D. Prevent corrosion
Rationale: Fire pumps increase water pressure to ensure proper
operation of sprinkler systems during fire events.
10. The minimum number of exits required for a room with an
occupant load of 50 is:
A. 1
B. 2
C. 3
D. 4
Rationale: NFPA and building codes require at least two exits for
rooms with more than 49 occupants.
11. Which type of sprinkler head is designed to operate only at a
specific temperature?
A. Dry pipe
B. Deluge
C. Standard response
D. Pre-action
Rationale: Standard response sprinkler heads activate when their
fusible element reaches a designated temperature.
12. In a dry pipe system, what fills the pipes before activation?
A. Water
B. Air or nitrogen
C. Foam
D. CO2
Rationale: Dry pipe systems contain pressurized air or nitrogen;
water enters the pipes only when the system activates.
13. Which type of fire alarm initiates signals automatically when
smoke or heat is detected?
