sprinkler system, standpipe, or other system. (Formally known as a Siamese connection) - ANS -Fire Department
Connection
\A device capable of removing all solids of sufficient size from water - ANS -Strainer
\A device designed to reduce, regulating, controlling or restricting water pressure - ANS -Pressure Regulating Devices
\A device that relieves excess water or air pressure from fire protection piping systems - ANS -Pressure Relief Valve
\A hose consisting of only a woven jacket that is usually of linen yarns and is of such quality that the yarn swells when
wet, tending to seal the hose - ANS -Unlined Hose
\A hose with a jacket covered and lined with synthetic rubber or plastic - ANS -Covered Hose
\A method of sizing automatic sprinkler systems indicating the design density, required Gallons per min, and pressure for
system to function properly - ANS -Hydraulic Calculated Systems
\A non-collapsible hose used under positive pressure having an elastomeric or thermoplastic tube, a braided or spiral
reinforcement, and an outer protective cover - ANS -Booster Hose
\A pilot operated pressure reducing valve that may be used with a fire or booster pump designed for the purpose of
preventing the incoming water supply from dropping below a set pressure - ANS -Pressure Control Valve
\A raised series of beams (usually steel) bearing on posts or walls to support mechanical equipment (usually on rooftops)
- ANS -Dunnage
\A sprinkler having special deflectors that are designed to discharge most of the water away from the nearby wall - ANS
-Sidewall Sprinkler
\A sprinkler head that directs 40% to 60% of water initially downwards with the deflector in either upright or pendant
position - ANS -Old style/Conventional Sprinklers
\A sprinkler head with a red frame has a temperature classification of? - ANS -Extra High (325 - 375°F)
, \A sprinkler head with a white frame has a temperature rating of? - ANS -175 - 225°F
\A sprinkler head with an orifice size from 3/4" - less than 1" - ANS -Large Orifice Sprinkler
\A standpipe system having piping containing water at all times - ANS -Wet standpipe system
\A standpipe system that is vertically subdivided as required by code into multiple zones in order to limit the maximum
operating pressure. Each zone will have it's own individual automatic water supply. - ANS -Standpipe, Multi-Zone

\A type of control valve for a sprinkler system in which the position of the center screw indicates whether the valve is open
or closed. - ANS -OS&Y (Outside Stem and yolk) Valve

\Allows full unobstructed flow and automatically closes when pressure is decreased. Fully closed when pressure reaches
zero and prevents back flow. - ANS -Swing Check Valve
\An automatic ball drip on a standpipe FDNY connection that leaks under normal conditions is - ANS -An indication of a
defective check valve
\Automatic ball drip device shall be - ANS -Installed in the horizontal position
