OS & Y valve - ANS indicating type of control valve used for fire sprinkler system deluge valve - ANS 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. INTENDED USE IS MANUAL AND AUTO deluge sprinkler system - ANS 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 IT OPENS, water flows into the piping system and discharges from all sprinklers attached. Early suppresion fast response sprinklers - ANS fast response sprinkler that is listed for its capability to provide fire suppression of specific high challenge fire hazards extra large orifice sprinklers - ANS = or 1 inch less pressure to achieve a given discharge density extended coverage sprinkler - ANS 400 max square feet discharge fire pump - ANS a provider of liquid flow and pressure dedicated to fire protection. A fire pump is a part of a fire sprinklers system water supply and can be powered by electric, diesel or steam. connected to public water source or tank. provides higher pressure to sprinkler system Glass bulb sprinkler - ANS operated by heat breaking a glass bulb filled with a non freezing liquid with diameters that vary form 3 mm for quick response to 5 mm for standard response hose valve - ANS valve to additional hose connection hydraulic placard - ANS sign attached to a hydraulically calculated sprinkler system indicating the design density, required gallons per minute and pressure for the system to operate properly hydraulically calculated systems - ANS method of sizing auto sprinkler piping using a prescribed amount of water to be distributed over a specific area. impairment coordinator - ANS in charge of safety during out of service systems intermediate level sprinkler - ANS sprinkler equipped with integral shields to protect the operating elemtn form discharge from sprinklers installed at higher elevations large orifice sprinkler - ANS sprinkler head with orifice size equal or greater than 3/4 and less than 1 inch listed device - ANS A fire protection component that has been tested to perform under parameters specified for its use by a nationally recognized testing agency. Underwriter's Laboratory (UL) and Factory Mutual (FM) are the two most common. Master Pressure Reducing Valve - ANS A pressure reducing valve installed to regulate pressures in an entire fire protection system and/or standpipe system zone. Main Drain - ANS The primary drain connection located on the system riser and also utilized as a flow test connection. Microbiologically Influenced Corrosion (MIC) - ANS Corrosion caused by the presence of microbes in the water supply that over time attack the interior of metallic piping and cause leaks, pitting, and blockages. Old-Style/Conventional Sprinkler - ANS A sprinkler that directs 40% to 60% of the water initially in a downward direction and is designed to be installed with the deflector in either the upright or pendent position. Pendent Sprinkler - ANS A sprinkler designed to be installed in such a way that the water stream is directed downward against the deflector. Pintle Screws - ANS A visual indicating device required for sprinklers manufactured prior to 1999 identifying small orifice sprinklers and large orifice sprinklers where orifice size is different than the nominal thread size of the sprinkler head. Pipe Schedule Systems - ANS A method of sizing piping based upon the number of sprinkler heads and the occupancy of the protected area. Preaction Sprinkler System - ANS A sprinkler system employing automatic sprinklers that are attached to a piping system that contains air that may or may not be under pressure, with a supplemental detection system installed in the same areas as the sprinklers. Pressure Control Valve - ANS 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 pressure from dropping below a set pressure. Pressure-Reducing Valve - ANS A valve designed for the purpose of reducing the downstream water pressure under both flowing (residual) and nonflowing (static) conditions. Pressure Relief Valve - ANS A valve designed for the purpose of releasing excess air or water pressure from the Fire Protection Piping System. Pressure Tank - ANS A tank using air pressure to supplying water for water-based fire protection systems. Tank contents to be maintained at one third air to two thirds water. Quick Response Sprinkler Head - ANS A sprinkler having a fusible link with a response time index (RTI) of 50 or less. Recessed Sprinkler - ANS A sprinkler in which all or part of the body, other than the shank thread, is mounted above the ceiling. Residential Sprinkler - ANS A type of fast response sprinkler that has been specifically tested to enhance survivability in the room of fire origin and listed for use in dwelling units.
