50 FL CV FIRE PROTECTION SYSTEM
CONTRACTOR EXAM 2026 COMPLETE STUDY
GUIDE
◉ Air sampling-type detector. Answer: A detector that consists of a
piping or tubing distribution network that runs from the detector to
the area(s) to be protected.
◉ Alarm check valve. Answer: AA valve that uses a clapper to
prevent backflow of water from the sprinkler system and initiates an
alarm when water flows through the system.
◉ Annunciator. Answer: A unit containing one or more indicator
lamps, alphanumeric displays, or other equivalent means in which
each indication provides status information about a circuit,
condition or location.
◉ Autoignition temperature. Answer: The lowest temperature at
which a combustible material ignites in air without a spark or flame.
◉ Automatic dry standpipe system. Answer: A standpipe system
permanently attached to a water supply capable of supplying the
system demand at all times, containing air or nitrogen under
, pressure, the release of which opens a dry pipe valve to allow water
to flow into the piping system and out of the opened hose valve.
◉ Backflow prevention device. Answer: A device or means designed
to prevent backward flow of liquids into the potable water system
◉ Bollards. Answer: Freestanding post typically filled with concrete
that is installed to protect fire hydrants.
◉ BTU. Answer: British Thermal Unit - the quantity of heat required
to raise the temperature of 1lb of water 1 degree.
◉ Butterfly Valve. Answer: Control valve that uses a flat circular
plate in a pipe that rotates 90 degrees across the cross section of the
pipe to control the flow of water.
◉ Candela. Answer: luminous intensity
◉ Carbon dioxide extinguishing system. Answer: A self-contained
and engineered suppression system that consists of liquid carbon
dioxide stored in container(s), activation devices, releasing
mechanisms, piping, fittings, and special spray nozzles; these
systems protect flammable and combustible liquid storage, chemical
storage, electrical hazards, marine/shipboard operations, industrial
