Questions and CORRECT Answers
ALARM NOTIFICATION APPLIANCE - CORRECT ANSWER - A fire alarm system
component, such as a bell, horn, speaker, light, text display or vibration device that issues an
audible, tactile, and/or visual alert.
ALARM SIGNAL - CORRECT ANSWER - A signal indicating an emergency requiring
immediate action, such as a signal indicative of fire.
ANTIFREEZE SPRINKLER SYSTEM - CORRECT ANSWER - A wet pipe sprinkler
system employing automatic sprinklers that are attached to a piping system that contains an
antifreeze solution
and is connected to a water supply. The antifreeze solution is discharged, followed by water,
immediately upon operation of sprinklers opened by heat from a fire.
AUTOMATIC BALL DRIP - CORRECT ANSWER - An automatic drain valve
horizontally installed at the low point in the piping between the lower check valve and the Fire
Department connection of automatic sprinkler systems. Water pressure from a Fire Department
pumper automatically closes this valve. It automatically re-opens when pressure ceases,
permitting this piping to drain and thereby preventing freezing.
CENTRAL STATION - CORRECT ANSWER - A facility that receives alarm signals
from a protected premises and retransmits or otherwise reports such alarm signals to the
department.
COMBINATION STANDPIPE AND SPRINKLER SYSTEM - CORRECT ANSWER -
A system where the water piping services both 21⁄2 in. (65 mm) outlets for fire
department use and outlets for automatic sprinklers.
CONCEALED SPRINKLER - CORRECT ANSWER - A recessed sprinkler with a cover
plate.
, CONTROL MODE SPECIFIC APPLICATION SPRINKLERS (CMSA) - CORRECT
ANSWER - Control mode sprinkler systems are designed to control a fire until its original
fuel source is depleted or until fire-fighting activities can commence. A fire is controlled by
cooling the ceiling-level air temperatures, reducing the fire's rate of heat release and pre-wetting
adjacent combustibles.
CONTROL VALVE - CORRECT ANSWER - A valve controlling flow to water-based
fire protection systems. Control valves do not include hose valves, inspector's test valves, drain
valves, trim valves for dry pipe, preaction and deluge valves, check valves, or relief valves.
OS&Y Valve - CORRECT ANSWER - (Outside Stem and Yoke valve) an indicating type
of control valve used for fire sprinkler system.
Curb Valve - CORRECT ANSWER - a non-indicating gate valve equipped with a cast
iron extension box flushed with a sidewalk with an operating nut of 1 1⁄4 inch, this valve is
operated using a special curb key wrench. This valve controls the municipal water supply serving
the fire sprinkler system.
CORROSION-RESISTANT SPRINKLER - CORRECT ANSWER - A sprinkler
fabricated with corrosion resistant materials, or special coatings to be used in an atmosphere that
would corrode standard sprinklers.
DEFICIENCY - CORRECT ANSWER - A condition in which the application of the
component is not within its designed limits or specifications.
CRITICAL DEFICIENCY - CORRECT ANSWER - A deficiency that, if not corrected,
can have an effect on the performance of the fire protection system.
NON CRITICAL DEFICIENCY - CORRECT ANSWER - A deficiency that does not
have an effect on the performance of the fire protection system, but correction is needed for the
proper inspection, testing, and maintenance of the system(s).
