FSDNY S-98 Exam Preparation: Randomized Scenario-Based MCQ Bank
Important Disclaimer: The actual FDNY S-98 Certificate of Fitness exam contains 80 multiple-
choice questions with a 160-minute time limit and a 70% passing score . There is no publicly
available official question bank containing 300 items. The questions below are synthesized from
verified exam content domains (NFPA 72, NYC Fire Code, electrical requirements, and
inspection procedures) to provide comprehensive coverage for study purposes. They are
formatted as scenario-based randomized MCQs with summarized rationales in italics.
Summarized Exam Coverage
The S-98 exam covers fire alarm system inspection, testing, and servicing per NFPA 72 (2016),
NYC Fire Code Chapter 9, Fire Department Rules, NYC Electrical Code, and Building Code
Section 907. Key domains include: initiating devices, notification appliances, secondary power
supplies, supervising station operations, inspection frequencies, records retention, and NYC-
specific installation requirements .
Randomized Scenario-Based MCQs (1–300)
1. A technician is inspecting a newly installed manual fire alarm box in a warehouse corridor.
The box is partially blocked by a stacked pallet. According to NFPA 72, the box must be
conspicuous, unobstructed, and:
A) Locked
B) Accessible
C) Painted red
D) Equipped with a break-glass cover
, Page 2 of 134
Answer: B
Rationale: NFPA 72 requires manual fire alarm boxes to be conspicuous, unobstructed, and
accessible so occupants can operate them without delay.
2. During a design review, an engineer asks how far a person should travel to reach the nearest
manual fire alarm box. What is the maximum travel distance?
A) 50 feet
B) 75 feet
C) 100 feet
D) 150 feet
Answer: C
Rationale: NFPA 72 limits travel distance to the nearest manual fire alarm box to 100 feet.
3. A technician is connecting waterflow switches to a single initiating device circuit (IDC). What
is the maximum number of waterflow switches permitted on one IDC?
A) 3
B) 5
C) 8
D) 10
, Page 3 of 134
Answer: B
Rationale: NFPA 72 restricts waterflow switches on a single IDC to no more than five.
4. An inspector is reviewing fire pump supervision. Which of the following is NOT required to be
supervised as a supervisory signal?
A) Pump running
B) Pump power failure
C) Pump phase reversal
D) Pump controller in auto mode
Answer: A
Rationale: Pump running is an alarm condition, not a supervisory signal. Supervisory signals
monitor off-normal conditions like power loss or phase reversal.
5. After the initial acceptance inspection, how often must nickel-cadmium and sealed lead-acid
batteries be inspected?
A) Monthly
B) Quarterly
C) Semi-annually
D) Annually
, Page 4 of 134
Answer: C
Rationale: After the first inspection, these battery types require semi-annual inspection.
6. A newly installed smoke detector has never been functionally tested. Within what time frame
must the first functionality test be performed?
A) 30 days
B) 6 months
C) 1 year of installation
D) 2 years
Answer: C
Rationale: The first functionality test of a smoke detector must occur within one year of
installation.
7. A technician is testing initiating device circuits on a conventional system. What is the
minimum number of detectors that must be tested on each initiating conventional device
circuit?
A) One
B) Two
