and maintenance (ITM) procedures is critical. This assessment emphasizes the application of professional
judgment to ensure life safety and property protection in accordance with the highest industry standards.
SECTION ONE: QUESTIONS 1 – 100
1. In a standard wet-pipe fire sprinkler system, what is the primary purpose of the main drain valve?
A. To provide a water supply for the fire department connection.
B. To allow for the removal of water from the system for maintenance.
C. To test the operation of the fire alarm system.
D. To control the flow of water to the sprinkler heads.
🟢 B. To allow for the removal of water from the system for maintenance.
🔴 Explanation: The main drain valve is installed at the system's riser to facilitate draining the entire
system for repairs, maintenance, or winterization. It is not a test valve for the fire alarm, nor does it
control the flow to individual heads; its primary function is to empty the system of water.
2. According to the Hawaii State Fire Code, which type of fire extinguisher is the minimum
requirement for a commercial kitchen cooking with grease?
A. Class A
B. Class B
C. Class C
D. Class K
,🟢 D. Class K
🔴 Explanation: Class K extinguishers are specifically designed for fires involving cooking oils and fats
(vegetable or animal) commonly found in commercial kitchens. They utilize a wet chemical agent that
saponifies the burning oil to prevent re-ignition.
3. What is the maximum allowable spacing for standard, 165°F (74°C) temperature-rated, standard-
response sprinkler heads in a light-hazard occupancy, assuming a standard pendant sprinkler with a
5/8-inch orifice?
A. 10 feet (3.0 m)
B. 15 feet (4.6 m)
C. 20 feet (6.1 m)
D. 25 feet (7.6 m)
🟢 B. 15 feet (4.6 m)
🔴 Explanation: The National Fire Protection Association (NFPA) 13 standard limits the maximum
spacing for standard spray sprinklers in light-hazard occupancies to 15 feet (4.6 m). This is a
fundamental design parameter to ensure adequate water distribution.
4. A fire alarm control panel (FACP) receives a signal from a smoke detector. Which type of initiating
device circuit is typically used to transmit this signal?
A. Notification Appliance Circuit (NAC)
B. Signaling Line Circuit (SLC)
C. Power Supply Circuit (PSC)
D. Audio Loop Circuit (ALC)
🟢 B. Signaling Line Circuit (SLC)
🔴 Explanation: In modern addressable fire alarm systems, initiating devices like smoke detectors are
connected to a Signaling Line Circuit (SLC). This circuit allows the FACP to communicate with each
device, receive status signals, and identify the specific device that has been activated.
5. In accordance with NFPA 70 (National Electrical Code), what is the minimum size of a copper
conductor required for a fire pump power feeder?
A. 8 AWG
B. 6 AWG
C. 2 AWG
D. The size is determined by the fire pump motor horsepower and voltage.
🟢 D. The size is determined by the fire pump motor horsepower and voltage.
🔴 Explanation: The minimum conductor size is not a fixed value but must be calculated based on the
electrical load (motor horsepower and voltage) and the length of the feeder to ensure it can handle
the locked-rotor current without excessive voltage drop, as per NFPA 70 and NFPA 20 requirements.
6. A contractor is installing a fire sprinkler system in a building with an estimated water demand of
1,500 GPM. The local water supply provides a residual pressure of 65 psi at the street main. What is
the most likely next step for the contractor?
, A. Proceed with installation, as 65 psi is sufficient for all systems.
B. Install a fire pump to increase the system pressure.
C. Immediately connect to the adjacent fire hydrant.
D. Reduce the size of the pipe in the system to increase pressure.
🟢 B. Install a fire pump to increase the system pressure.
🔴 Explanation: A demand of 1,500 GPM generally requires a pressure much higher than 65 psi at the
sprinkler head to achieve the required density. A fire pump is necessary to boost the water supply
pressure to meet the system's hydraulic demands.
7. Which of the following is the MOST important consideration when designing a fire alarm system
for a high-rise building?
A. The color of the alarm pull stations.
B. The number of stairwells in the building.
C. The integration of the alarm system with the smoke management system.
D. The location of the nearest fire hydrant.
🟢 C. The integration of the alarm system with the smoke management system.
🔴 Explanation: In high-rise buildings, life safety heavily depends on smoke control and evacuation
strategies. The fire alarm system must interface with smoke management systems to control the
spread of smoke, ensure safe egress, and provide clear communication to building occupants.
8. What does the acronym "AHJ" stand for in the context of fire codes?
A. American Housing Journal
B. Authority Having Jurisdiction
C. Automatic Hydraulic Jack
D. Annual Hazard Inspection
🟢 B. Authority Having Jurisdiction
🔴 Explanation: AHJ is a fundamental term referring to the organization, office, or individual
responsible for enforcing the requirements of a code or standard, or for approving equipment,
materials, an installation, or a procedure (e.g., the local fire marshal).
9. A contractor installs a fire sprinkler system and submits an "as-built" drawing. What is the
primary purpose of this document?
A. To serve as a marketing tool for the company.
B. To provide a record of the exact installation for future maintenance and modifications.
C. To apply for a building permit.
D. To calculate the total cost of the project.
🟢 B. To provide a record of the exact installation for future maintenance and modifications.
🔴 Explanation: The as-built drawing is a crucial record that reflects the "as-installed" system, detailing
the exact location of pipes, fittings, hangers, and devices. It is an essential reference for the building
owner, facility managers, and future contractors for maintaining, inspecting, or modifying the system.
