S-95 FDNY Test Questions and Answers
(2026/2027) | Updated Review | A+ Verified
• What Can A S95 Holder do? -✓✓Only visual inspections on smoke alarms
• Primary Purpose of Fire Alarm Systems -✓✓on a premise is to warn tenants and
transmit signals indicating a fire condition to the FDNY aka Central station
• Fire Alarm Control Panel (FACP) -✓✓Monitors inputs and controls output
through various types of circuits.The Panel activates the building audible and
visual device connected to the fire alarm (horn/strobes)
• Three Types of Signals -✓✓Fire Alarm Signal, Supervisory Signals, and Trouble
Signals
• Fire Alarm Signal -✓✓Manual fire alarm pull station, smoke detector, water
flow switch in the
presence of a fire or fire signature.
• Supervisory Signals -✓✓Signals which Indicate that a system or device being
monitored has been compromised or is in an abnormal state. Will audibly and
visually annunciate at the FACP to indicate the condition needs to be investigated
and corrected. The FACP will also send a signal to an FDNY approved central
station.
• Trouble Signals -✓✓Battery failure, AC failure, ground fault, open or short
circuit on a wire, phone line failure, internal component failure.
• Alarm Silence Switch or Button -✓✓Is used to silence the building audible and
visual
devices after evacuation is complete while the source of alarm is being
investigated. Never reset the fire alarm system until the condition is verified by the
FDNY personnel.
• System Reset Switch Or Button -✓✓Reset fire alarm system after condition is
cleared. Should return to normal condition after resetting. Often required to clear
supervisory conditions, does not clear trouble conditions.
, • Smoke detectors must be -✓✓Cleaned once every 6 months. Test for smoke
entry every once a year
• Primary Power -✓✓shall be generated electric power not exceeding 277/480
volts
• Secondary Power Source -✓✓Batteries shall not be a sub for connection to the
secondary source
• Manual Pull Station~Manually pulling handle -✓✓Return handle to normal
position. A key or other method may be required to reset the station to normal
• Smoke, beam, and duct detectors~ Detection of particles of combustion -
✓✓Smoke detectors will normally reset when the reset button is pressed at the
FACP if the condition activating the detector has been cleared
• Heat detectors~ Abnormally high temperature -✓✓After activation most Fixed
temperature heat detectors will not self restore and will require replacement by a
qualified service technician. Rate of rise detectors will normally self- restore after
activation.
• Water-Flow device~ Flow of water in a sprinkler system -✓✓Device should
return to normal when water ceases to flow.
• Smoke Detectors -✓✓Smoke Detectors is a device that detects visible and
invisible particles of combustion. Smoke detectors detect most fires much more
rapidly than heat detectors. Smoke detectors are subject to mechanical damage
they shall be protected.
• Ionization detectors -✓✓use an ionization chamber and a source of ionizing
radiation to detect smoke.
better at detecting the smaller amounts of particles of combustion.
• Photoelectric detectors -✓✓Respond to smoke, which obscures a light beam in
the device. Useful where potential fires may produce a great deal of smoke before
bursting into flames
