S-95 (Supervision of Fire Alarm Systems)
TEST QUESTIONS AND ANSWERS BEST FOR
EXAM PREP AND GUARANTEED PASS.
What is the purpose of elevator lobby smoke detectors?
When activated they will recall elevators automatically to the designated
landing
What are duct smoke detectors?
They are used to help prevent smoke from spreading from the fire area to other
parts of the building by shutting down the HVAC system
Why should duct detectors be tested?
To ensure that device samples the air stream
Why is the HVAC system and the FAS interfaced?
So that in the event of a fire alarm signal the alarm will shut down air handling
system area
How do sampling type smoke detectors work?
They work by using a sampling tube to draw in a sample of air from the hazard
area to the detector where the presence of visible or invisible combustion
products is determined
What is the purpose of spot type detectors?
The purpose is for location and spacing
What should be the maximum air sample transport time from farthest
sampling point?
No more than 120 seconds
,What are addressable system smoke detectors?
They are detectors that provide an alarm indication to a control unit as well as
signal the location of the alarm
What are intelligent system smoke detectors?
They are detectors that send information about smoke condition to control
unit
It also indicates location and provides environmental change information to
panel
What is the purpose of smoke detectors with control output functions?
The control output function regulate the different devices on the circuit
What are smoke dampers?
They open and close when required to provide fresh air or to stop smoke
passage
What are fire dampers?
They close when a rise in temperature occurs and stay shut to stop fire from
passing through a barrier
What is an elevator recall?
This when the fire alarm system integrates with elevator control to recall
elevator cars to a designated landing floor in the even of an alarm
What is a door release ( where connected to FACP)?
This is when the FAS will actuate a relay to release door holders so those will
automatically close to provide a smoke barrier between two areas
What are heat detectors?
They are sensors that detect abnormally high temp or rate of temperature rise
, What are the two types of heat detectors?
They are rate of rise and fixed temperature
Who can test heat detectors?
Only authorized fire alarm technicians
What are rate of rise heat detectors?
They are detectors that activate alarm when the room temperature increase at
a rapid rate
Does rate of rise detector have to be replaced after activation?
No
What is a fixed temperature heat detector?
They are detectors that activate alarms when the detector components melt
at a preset temperature level
How do heat detectors work?
The 2 electrical contacts are brought together after fusible element melts,
which activated alarm
What is the purpose of sprinkler water flow alarm initiating device?
They are use to detect the flow of water in a fire sprinkler system and to send
an alarm signal
What premises are carbon monoxide detectors required?
They are required in any building that has fossil (gas/oil) fuel burning
equipment
What is a carbon monoxide detector?
