Underwriter's Laboratory (UL) and Factory Mutual (FM) are the two most common. Master Pressure Reducing Valve - ¥ VA pressure reducing valve installed to regulate pressures in an entire fire protection system and/or standpipe system zone. Main Drain - V /The primary drain connection located on the system riser and also utilized as a flow test connection. Microbiologically Influenced Corrosion (MIC) - // 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. Conventional Sprinkler - /WA sprinkler that directs 40% to 60% of the water initially ina downward direction and is designed to be installed with the deflector in either the upright or pendent position. Pendent Sprinkler - / VA sprinkler designed to be installed in such a way that the water stream is directed downward against the deflector. 17 Quick Response Sprinkler Head - /WA sprinkler having a fusible link with a response time index (RTI) of 50 or less. Recessed Sprinkler - / WA sprinkler in which all or part of the body, other than the shank thread, is mounted above the ceiling. Residential Sprinkler - / WA 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. Response Time Index (RTI) - YW A measurement of the thermal sensitivity of a sprinkler head expressed in (meters-seconds) 1/2. Supervisory signal - / VA signal indicating the need for action or the use of such device in connection with the supervision of fire alarm systems or the maintenance features of related systems. Small orifice sprinklers - /V/A sprinkler head with and orifice size smaller than 1/2" Solder Link Sprinkler - //A sprinkler operated by the melting of a metal link, they vary in size and configuration for quick response and standard response sprinklers. The smaller the size of the link, the faster the sprinkler operates. Spray Sprinkler - //A type of sprinkler listed for its capability to provide fire control for a wide range of fire hazards. The most commonly used sprinkler since 1953. 19 Standard Response Sprinkler Head - VA sprinkler having a fusible link with a response time index (RTI) of 80 or more. Supervisory signal-initiating device - / VAn initiating device, such as a valve supervisory switch, that triggers a supervisory signal. Testing - VA procedure used to determine the status of a system as intended by conducting periodic physical checks on water based fire protection systems such as waterflow tests, fire pump tests, alarm tests, and trip tests of dry pipe, deluge, or preaction valves. These tests follow up on the original acceptance test at intervals specified in the appropriate chapter of NFPA #25, 2002 edition. Upright Sprinkler - /A sprinkler designed to be installed in such a way that the water spray is directed upwards against the deflector. Water Spray Fixed System - V VA special fixed pipe system connected to a reliable fire protection water supply and equipped with water spray nozzles for specific water discharge and distribution over the surface or area to be protected. The piping system is connected to the water supply through an automatically or manually actuated valve that initiates the flow of water. An automatic valve is actuated by operation of automatic detection or manual release equipment installed in the same areas as the water spray nozzles. (In special cases, the automatic detection system may also be located in another area.) PREACTION SPRINKLER SYSTEMS - / designed for situations where there is danger of serious water damage. Water damage is usually caused by damaged sprinklers or broken piping. Under normal conditions there is no water in the piping. The air in the piping may or may not be is under pressure. A preaction valve prevents the water from entering the system. The valve is automatically opened when a fire detection system discovers that there is a fire or smoke condition. The preaction valve is tripped by 20
