Antifreeze Sprinkler System - 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
/.Combination Standpipe And Sprinkler System - Answer-A system where the water
piping services both 2 ½" outlets for FD use and outlets for automatic sprinklers
/.Deluge Sprinkler System - Answer-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 - Answer-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, (as from the opening of a sprinkler) results in the water
pressure opening a valve known as a dry pipe valve, resulting in the flow of water into
the piping system and out of the fused sprinklers heads.
/.Fire Alarm System - Answer-Any system, including any interconnected fire alarm sub-
system, of components and circuits arranged to monitor and annunciate the status of
fire alarm or supervisory signal-initiating devices
/.Fire Extinguishing System - Answer-Approved devices, equipment and system of
devices and equipment which detects a fire and discharges an approved fire
extinguishing agent onto or in the area of a fire. Such term includes automatic systems
and, where such systems are authorized by this code or the building code, manually
activated systems
/.Fire Protection System - Answer-Approved devices, equipment and systems or
combinations of systems used to detect a fire, activate an alarm, extinguish or control a
fire, control or manage smoke and products of a fire or any combination thereof,
including fire extinguishing systems, fire alarm systems, sprinkler systems and
standpipe systems
/.Hydraulically Calculated Systems - Answer-A method of sizing automatic sprinkler
piping using a prescribed amount of water to be distributed over a specific area
