The preaction valve can also be operated manually.<\/p>\n\n\n\n

DELUGE SPRINKLER SYSTEMS
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.
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.<\/p>\n\n\n\n

NON-AUTOMATIC DRY SPRINKLER SYSTEMS
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.<\/p>\n\n\n\n

Curb Valves
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.<\/p>\n\n\n\n

Fire Pumps
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.<\/p>\n\n\n\n

Waterflow Alarm Valves
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.<\/p>\n\n\n\n

Vane type waterflow
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.<\/p>\n\n\n\n

Alarm Retarding Devices
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.<\/p>\n\n\n\n

The Centrifugal Pump
The centrifugal fire pump is the standard pump currently used in fire protection systems. This is the preferred pump because it is reliable, compact, requires low maintenance, and it can be powered by a variety of drivers including: electric motors, internal combustion engines, and steam turbines<\/p>\n\n\n\n

The Vertical Turbine Pump
A vertical turbine pump is really a modified centrifugal pump that has the capability to draw water from streams, ponds, wells etc. Unlike the standard centrifugal pump, the vertical turbine pump does not need the suction supply to be under pressure for it to operate. Instead it draws the water into the pump by suction. The water is drawn into the pump. When it reaches the rotating impellers the water pressure is increased and then forcefully discharged into the fire protection system.<\/p>\n\n\n\n

Pump Activation
A fire pump can be started automatically or manually. The pump can be started automatically by an electric controller or an engine controller. These controllers activate the pump when there is a drop of water pressure or water flow in the fire protection system.<\/p>\n\n\n\n

Pressure Maintenance Pumps (Jockey Pumps)
Pressure maintenance pumps,
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.<\/p>\n\n\n\n

Booster pumps\/special service pumps
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.<\/p>\n\n\n\n

Sprinkler system piping
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.<\/p>\n\n\n\n
