These tests follow up on the original acceptance test at intervals specified in the appropriate chapter of NFPA #25, 2002 edition.
Upright Sprinkler - ANSWERS-A sprinkler designed to be installed in such a way that the water spray is directed upwards against the deflector.
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.
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.
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.
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.
Pumper Connections for Fire Department Use - ANSWERS-Fire Department connections must always be accessible. Each connection shall be fitted with a lower check valve. The lower check valve prevents the backflow of the private water supply into the Fire Department connection. The figure below shows the main features of a Fire Department connection.
Fire Pumps - ANSWERS-used as a main water supply source for sprinkler systems. They may also be used in combination with gravity tanks to supply sprinkler system. Fire pumps are designed to take the water from a supply source and then discharge the water into the fire protection system under pressure.
Waterflow Alarm Valves - ANSWERS-The basic design of most water-flow alarm valves is that of a check valve which lifts from its seat when water flows into a sprinkler system. This alarm then starts an audible signal to alert the occupants in the building that the sprinkler system has been activated.
Vane type waterflow - ANSWERS-Switches have a paddle inserted inside the main supply piping perpendicular to the direction of flow. Upon waterflow, the paddle switch transmits an alarm. Vane type waterflow switches cannot be installed to monitor waterflow in dry pipe sprinkler systems.
Alarm Retarding Devices - ANSWERS-An alarm check valve that is exposed to changing water supply pressure needs an alarm retarding device. This is required to prevent false alarms when the check valve clapper is lifted from its seat by a temporary pressure surge. Vane type water flow switches sensitivity can also be adjusted to changing water pressures.
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.
Sprinkler system piping - ANSWERS-Branch lines are directly connected to sprinkler heads.
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.
rti - ANSWERS-response time index
full flow test - ANSWERS-performed every 5 years:
- open main valve to let debris escape, then close
- system air a nd water pressrue recorded.
- relieve pressure by opening inspector test valve (use stopwatch)
- at dry pipe valve note aire pressure which valve trips an note time
- at inspectors test note time that water flows steadily.
- test terminated when clean water flows (shit valve)
compare to past tests

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.
Fire Pump - ANSWERS-A pump that is a provider of liquid flow and pressure dedicated to fire protection. A fire pump is a part of a fire standpipe system's water supply and can be powered by electric, diesel or steam. The pump intake is either connected to the public underground water supply piping or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at higher pressure and volume to the standpipe system risers and hose standpipes.
