S-95 (FDNY) Questions and Answers
Analog (intelligent) Smoke Detectors : Correct Answer- shall be cleaned no later than one
(1) week from receipt of an indication of the need for cleaning.
Smoke detectors : Correct 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 : Correct 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 : Correct 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 : Correct Answer- After activation most detectors will
NOT self restore and will require replacement by a qualified service technician.
Rate of rise heat detectors : Correct Answer- will normally self-restore after activation.
Water-flow device : Correct 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 : Correct 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 : Correct 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 : Correct Answer- (1) Visual inspection of smoke detectors
(2) Visual inspection of other fire alarm system components
Primary purpose of fire alarm systems : Correct Answer- to warn building occupants and
transmit signals indicating a fire condition to the fire department via an FDNY approved
central station company.
3 Types of Signals Initiated by FACP : Correct Answer- *Fire Alarm Signal
*Supervisory Signal
*Trouble Signal
Fire Alarm Control Panel (FACP) : Correct 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 : Correct 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 : Correct Answer- indicates that a system or device being monitored has
been compromised or is in an abnormal state.
*The FDNY will receive this signal but it's NOT dispatched to respond.
