FDNY S14 Supervision of Multi-Zone Standpipe System Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary purpose of a multi-zone standpipe system?
• Provide water for domestic use
• Manage HVAC demands
• Deliver firefighting water pressure across varying building heights
• Reduce sprinkler demand

Rationale: A multi-zone standpipe divides tall buildings into pressure-

controlled zones to ensure usable firefighting pressure on all floors.

• Which NFPA standard governs standpipe systems?

A. NFPA 10

B. NFPA 14 1 / 4

C. NFPA 25

D. NFPA 72

Rationale: NFPA 14 is the installation standard for standpipe and hose

systems.

3. A Class I standpipe system provides outlets for:

• Occupants only
• Office staff
• Firefighters using 2½-inch hose connections
• Automatic sprinklers only

Rationale: Class I systems are intended for trained fire personnel using

large-diameter hose connections.

• Who may supervise an S-14 standpipe system during non-fire

emergency periods?

• Any staff member
• Certificate of Fitness holder
• Only FDNY
• Building visitors

Rationale: FDNY requires a certified individual to supervise standpipe

operations.

5. In a multi-zone standpipe, pressure-reducing devices are installed to:

• Increase flow
• Prevent leaks
• Limit excessive outlet pressure
• Test valves

Rationale: Upper zones may experience high pressures requiring regulated

control at outlets.

• The required minimum residual pressure at the most remote 2½-inch

outlet is:

• 25 psi
• 65 psi
• 100 psi
• 10 psi

Rationale: NFPA 14 requires 65 psi residual at the hydraulically most

remote hose valve.

7. Standpipe risers must be kept:

• Uninsulated
• Free of obstructions
• Hidden behind storage
• Closed at both ends 3 / 4

Rationale: Access must be maintained for emergency operations and

inspections.

8. Automatic standpipe systems receive water from:

• Portable pumps
• Street main and fire pump
• HVAC equipment
• Domestic tanks only

Rationale: Automatic systems supply water immediately from pressurized

sources.

9. Manual standpipe systems require:

• Built-in pump activation
• Gravity tanks only
• Fire department pumper connection for pressure
• No water source

Rationale: Manual systems depend entirely on FDNY apparatus for

pressure.

• A standpipe zone typically covers how many stories in super-tall

buildings?
