S12 FDNY Exam (Latest 2025/2026
Update) Questions and Verified
Answers | 100% Correct | Grade A
Question 1
What is the primary purpose of the Remote Station Supervisory Service (RSSS) as updated in the
2025 NYC Fire Code?
A. To monitor water levels only
B. To transmit supervisory signals for flow, pressure, and valve status to a central station
C. To activate alarms during emergencies
D. To test system hydraulics annually
Rationale: Per 2025/2026 updates to NYC Fire Code Section 903.4, RSSS ensures continuous
monitoring of critical sprinkler parameters, allowing rapid response to impairments like low
pressure or closed valves, enhancing system reliability.
Question 2
Under the 2026 Local Law amendments, what is the maximum allowable RTI (Response Time
Index) value for quick-response sprinklers in light hazard occupancies?
A. 50 (m·s)^0.5
B. 80 (m·s)^0.5
C. ≤50 (m·s)^0.5
D. 100 (m·s)^0.5
Rationale: NFPA 13 (integrated 2022 edition in 2025 FDNY rules) specifies RTI ≤50 for quick-
response heads in light hazard areas to ensure faster activation, reducing fire spread in
commercial spaces.
Question 3
What color code is required for the dry pipe riser in a preaction sprinkler system according to
2025 FDNY standards?
A. Black
B. White
C. Red
D. Green
Rationale: FDNY Bulletin 2025-02 mandates white for preaction risers to distinguish from wet
(black) and dry (red) systems, aiding inspectors in quick identification during inspections per
Local Law 196.

Question 4
In deluge systems, what is the minimum water flow rate per square foot for high-hazard
occupancies as per 2026 updates?
A. 0.15 gpm/ft²
B. 0.25 gpm/ft²
C. 0.30 gpm/ft²
D. 0.45 gpm/ft²
Rationale: Updated NFPA 15 (2022) via 2026 FDNY code requires at least 0.30 gpm/ft² over
3,000 ft² for deluge in high-hazard areas like flammable liquid storage to achieve rapid
suppression.
Question 5
Which antifreeze solution is prohibited in new installations under 2025 NYC Fire Code
sustainability amendments?
A. Propylene glycol
B. Glycerine
C. Ethylene glycol
D. All of the above
Rationale: Local Law 202 of 2024 (effective 2025) bans ethylene glycol due to environmental
toxicity; only propylene glycol or glycerine (≤48% concentration) are permitted for freeze
protection in unheated areas.
Question 6
What is the required clearance below sprinklers in ordinary hazard occupancies per 2026 FDNY
rules?
A. 12 inches
B. 18 inches
C. 24 inches
D. 36 inches
Rationale: NFPA 13 Section 8.7.6.1, adopted in 2026 updates, mandates 18 inches minimum
from storage or obstructions to prevent obstruction of spray patterns, ensuring effective water
distribution.
Question 7
For RTI calculations in extended coverage sprinklers, what factor must be considered in the
2025/2026 FDNY exam standards?
