S-95 FDNY COMPREHENSIVE EXAM 2026
QUESTIONS WITH ANSWERS GRADED A+
◉ Smoke detectors. Answer: MUST BE: (1) cleaned not less than once
every six (6) months
(2) tested for smoke entry not less than once a year.
◉ Smoke, beam, and duct detectors. Answer: (1) Activated by detection
of particles of combustion
(2) causes Fire Alarm
(3) normally resets when the reset button is pressed at the FACP if the
condition activating the detector has been cleared.
Must be protected from the entrance of foreign particles that may be
airborne. Ex: Dust from cutting wood, sheet rock or sanding may trigger
a false alarm.
◉ Heat detectors. Answer: (1) Activated by abnormally high
temperature (fixed temperature detector) or rapid temperature rise (rate
of rise detector).
(2) causes Fire Alarm
,◉ Fixed temperature heat detectors. Answer: After activation most
detectors will NOT self restore and will require replacement by a
qualified service technician.
◉ Rate of rise heat detectors. Answer: will normally self-restore after
activation.
◉ Water-flow device. Answer: (1) Activated by Flow of water in a
sprinkler system
(2) causes fire alarm signal
(3) Device should return to normal when water ceases to flow.
◉ Manual Pull Station. Answer: (1) Activated by manually pulling
handle
(2) causes fire alarm
(3) Return handle to normal position. A key or other method may be
required to reset the station to a normal condition.
◉ Primary power source. Answer: shall be generated electric power not
exceeding 277/480 volts, supplied by utility company power or isolated
plant
◉ Duties performed by CoF S-95. Answer: (1) Visual inspection of

department via an FDNY approved central station company.
◉ 3 Types of Signals Initiated by FACP. Answer: *Fire Alarm Signal
*Supervisory Signal
*Trouble Signal
◉ Fire Alarm Control Panel (FACP). Answer: a system component that
monitors inputs and control outputs through various circuits. Its primary
purpose is to process signals received from initiating devices and to
activate appropriate signals and outputs.
*There are 3 types of signals initiated by it.
◉ Fire Alarm Signal. Answer: A signal initiated by a fire alarm initiating
device such as a manual fire alarm pull station, smoke detector, water-
flow switch, or other device in which activation is indicative of the
presence of a fire or fire signature.
◉ Supervisory Signal. Answer: indicates that a system or device being
monitored has been compromised or is in an abnormal state.
