FDNY S12
Alarm Notification Appliance - ANS -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 - ANS -a signal indicating an emergency requiring immediate action, such as a signal indicative of fire
\Antifreeze Sprinkler System - ANS -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; discharged followed by water,
immediately upon operation of sprinklers opened by heat from a fire
\Automatic Ball Drip - ANS -An automatic drain valve horizontally installed at the low point in the piping between the lower
check valve and the FD connection of automatic sprinkler systems. Water pressure from a FD pumper automatically
closes this value. It automatically re-opens when pressure ceases, permitting this piping to drain and thereby preventing
freezing
\Central Station - ANS -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 - ANS -a system where the water piping services both 2.5 in. outlets for fire
department use and outlets for automatic sprinklers
\Concealed Sprinkler - ANS -A recessed sprinkler with a cover plate
\Control Valve - ANS -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, reaction and deluge valves, check valves, or relief
valves
\Controle Mode Specific Application Sprinklers - ANS -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
\Corrosion-Resistant Sprinkler - ANS -A sprinkler fabricated with corrosion resistant materials, or special coatings to be
used in an atmosphere that would corrode standard sprinklers
\Critical Deficiency - ANS -A deficiency that can have an effect on the performance of the fire protection system
