FDNY S12 EXAMS SCRIPT 2025/2026 QUESTIONS AND
SOLUTIONS GRADED A+
✔✔Non Critical Deficiency - ✔✔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
✔✔Deluge Valve - ✔✔A water supply control valve intended to be operated by
actuation of an automatic detection system that is installed in the same area as the
discharge devices. Each deluge valve is intended to be capable of automatic and
manual operation.
✔✔Deluge Sprinkler System - ✔✔A sprinkler system employing open sprinklers that are
attached to a piping system that is connected to a water supply through a valve that is
opened by the operation of a detection system installed in the same areas as the
sprinklers. When this valve opens, water flows into the piping system and discharges
from all sprinklers attached.
✔✔Dry Pipe Sprinkler System - ✔✔A sprinkler system employing automatic sprinklers
that are attached to a piping system containing air or nitrogen under pressure. The
release of the air or nitrogen results in the water pressure opening a valve known as a
very pipe valve, resulting in the flow of water into the piping system and out of the fused
sprinklers heads.
✔✔Dry Sprinkler - ✔✔A sprinkler secured in an extension nipple that has a seal at the
inlet to prevent water from entering the nipple until the sprinkler operates. May be
configured with an upright pendent or sidewall sprinkler.
✔✔Discharge device - ✔✔A device designed to discharge water or foam-water solution
in a pr
✔✔Early Suppression Fast Response Sprinkler - ✔✔A type of fast response sprinkler
that is listed for its capability to provide fire suppression of specific high challenge fire
hazards
✔✔Extra Large Orifice Sprinklers - ✔✔A sprinkler head with an orifice size equal to or
greater than 1 inch. this sprinkler is used for protection of high piled storage in
warehouses and less pressure is required to achieve a given discharge density
✔✔Extended Coverage Sprinklers - ✔✔A type of spray sprinkler with a max area of
coverage of 400 square feet for light hazard occupancies to a max of 144 square feet
for extra hazard occupancies
✔✔Fire Alarm System - ✔✔any system of components and circuits arranged to monitor
and annunciate the status of fire alarm or supervisory signal-initiating services
