  4. Supervisory signal-initiating device - answers> An initiating device, such as a valve supervisory switch,that triggers a supervisory signal.
  5. Testing - answers> A 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.
  6. Upright Sprinkler - answers> A sprinkler designed to be installed in such a way that the water spray is directed upwards against the deflector.
  7. Water Spray Fixed System - answers> A 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.)
  8. PREACTION SPRINKLER SYSTEMS - answers> 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 the fire detection system before any of the

sprinkler heads open. A supervisory device signals when the valve is opened. The preaction valve can also be operated manually.

  1. DELUGE SPRINKLER SYSTEMS - answers> equipped with open sprinkler heads designed to wet down an entire area involved in a fire. This system is needed when there is danger of a fire rapidly spreading throughout the building. The deluge system will slow down the spread of the fire. Deluge systems are suitable for hazardous occupancies. This includes buildings in which flammable liquids or other hazardous materials are handled or stored.
  2. The sprinkler heads in the deluge system are open at all times. Under normal conditions there is no water in the piping. The air in the piping is not under pressure. A closed control valve prevents water from flowing into the system. A fire detection device automatically opens the control valve when a fire is identified. A supervisory device signals when the valve is opened. When the valve is opened water flows into the system. The water is then discharged out all of the sprinkler heads. The water control valve may also be opened manually.
  3. NON-AUTOMATIC DRY SPRINKLER SYSTEMS - answers> ll pipes are normally dry. Water is supplied when needed by pumping water into the system through the Fire Department connection. Some of these systems are supplied by manual operation of a water control valve and may be equipped with sprinklers with or without fusible links.
  4. There are several non-automatic systems: 1) Perforated pipe systems - a single line of piping drilled at intervals for water discharge. These systems are usually found in basements or other areas difficult to reach in fire fighting operations. 2) Open fixed spray nozzles for transformer vaults or other hazardous areas; 3) exterior exposure sprinklers (or window sprinklers) use open sprinkler heads to form an external water curtain on the walls of a building, and 4) Foam supply systems are used for the protection of special hazardous occupancies.
  5. Curb Valves - answers> Gate valves of the non-indicating type are provided in water distribution systems. Gate valves allow the sprinkler system to be shut off for repairs or maintenance. Such valves are normally a non-rising stem type. They are operated using a special key wrench. A valve box is located over the valve to keep dirt from the valve. The valve box also provides a convenient access point for the valve wrench to the valve nut. A complete record should be made for each valve in the system. This record should include the exact location, the date it was installed, the make, the direction of opening, number of turns to open, and any maintenance that was performed.
  6. The control valve for the building may also be on the outside wall or attached to an upright post, known as a post indicator valve (PIV). The building or section of the building controlled by the valve is usually marked on the post. The position of this valve (open or closed) is shown through a telltale opening in the post. On some posts, a padlock must first be opened to release the operating wrench or wheel handle.
  1. Pressure Maintenance Pumps (Jockey Pumps) - answers> Pressure maintenance pumps,
  2. Some times referred to as jockey, or makeup pumps, are often found on sprinkler systems. These pumps are designed to automatically operate when there is a slight drop in pressure due to the leakage in the system or a pressure surge. The jockey pump restores the pressure in the fire protection system to the desired level. When the drop of pressure in the system greater than the capacity of the jockey pump the fire pump is activated.
  3. Booster pumps/special service pumps - answers> Booster pumps are sometimes used in sprinkler systems. They small pumps with limited power are usually located in the basement or taking suction from gravity tanks. The booster pump is used when the water pressure available at the highest sprinkler head does not quite meet the needs of the sprinkler system. This small pump increases the water pressure in the sprinkler system until it reaches acceptable levels. The booster pump should not be confused with the fire pump or the jockey pump.
  4. Sprinkler system piping - answers> Branch lines are directly connected to sprinkler heads.
  5. Cross mains or loop mains are directly connected to branch lines. Feed mains are directly connected to cross mains or loop mains. Risers are able to supply feed mains or cross mains directly.
  6. rti - answers> response time index
  7. full flow test - answers> performed every 5 years:
  8. open main valve to let debris escape, then close

  12. at inspectors test note time that water flows steadily.
  13. test terminated when clean water flows (shit valve)
  14. compare to past tests
  15. fire hydrant - answers> A valve connection on a water supply system having one or more outlets and that is used to supply hose and fire department pumps with water.
  16. Control valve - answers> A valve controlling flow to water base fire protection system. Control valve do not include hose valves
