CH. 12 Water-Based Fire Suppression
Systems (I)
Which type of automatic sprinkler is designed to direct 40 to 60 percent of its discharge
in a downward direction? - answer Old-style/conventional
Which of the following statements about water flow control valves in automatic sprinkler
systems is MOST accurate? - answer They must be indicating-type valves.
Which classification of standpipe and hose systems is designed to be used by both fire
department personnel and trained building occupants? - answer Class III
Most fires in sprinkler-equipped structures are controlled by the operation of: -
answerone or two of the sprinklers.
Which fire pump is very useful for lifting water from a source below the pump? -
answerVertical turbine
Which method is the MOST accurate for determining the pipe diameters of automatic
sprinkler system pipes? - answerHydraulic calculations
Which classification of standpipe and hose systems is primarily for use by firefighters
trained in handling large handlines (2½-inch [65 mm] hose)? - answerClass I
Which type of standpipe system contains unpressurized air in pipes and has no
permanent water supply? - answerManual-dry
Which operating valve is provided in automatic sprinkler systems to limit the flow of
water to one direction? - answerCheck valves
Which type of automatic sprinkler is mounted horizontally from a wall face so that the
deflector causes the water to be distributed in an arc over the protected area? -
answerSidewall
Which automatic sprinkler system is typically provided in areas where freezing
temperatures are likely to occur? - answerDry-pipe sprinkler system
What is a primary concern for residential sprinkler systems installed according to
NFPA® 13? - answerLife safety
, Which fire protection system discharges water over the area or surface of electrical
equipment to be protected through an arrangement of pipes and nozzles? -
answerWater-spray fixed system
Which stationary fire pump's main advantage is its compactness? - answerVertical split-
case
For a fire suppression system to be effective, it must be reliable and: - answerautomatic.
Which fire protection system requires a proportioner? - answerFoam-water system
Which of the following is a factor that determines the minimum waterflow required for an
automatic sprinkler system? - answerHazard being protected
Which of the following is a reason for use of pressure regulating devices at hose
outlets? - answerPrevent pressures that make fire hose difficult or dangerous to handle
Which fire protection system is considered a replacement for fixed fire suppression
systems that used halogenated hydrocarbon agents? - answerWater-mist system
All sprinklers discharge water simultaneously in: - answerdeluge sprinkler systems.
Which automatic sprinkler system is continually charged with air under pressure
combined with a detection system that controls the operation of the waterflow control
valve? - answerCombined dry pipe and preaction sprinkler system
Which are vertical sections of pipe that connect the underground supply to the rest of
the piping in the system? - answerSystem risers
Which pressure-regulating device at a hose outlet is preferred for managing excessive
pressure and is considered to be the most reliable method of pressure control? -
answerPressure-control devices
Which sprinkler system device activates preaction and deluge systems by smoke, heat,
or rate-of-rise detectors in the protected area? - answerElectronic heat detector
Which of the following is the main function of a stationary fire pump? - answerIncrease
the pressure of the water that flows through it
Which of the following drivers provides steam pressure to drive both horizontal and
vertical split-case pumps directly? - answerSteam turbine
Which valve is used to drain water from piping when pressure is relieved in the pipe? -
answerDrain valves
