What is a Fire Sprinkler System?

• A fire sprinkler system may be a series of
  sprinkler heads connected to a pipe that's full
  of water. That easy huh! If do not assume so.
• A fire sprinkler system may be a well-designed
  system designed to place or management fires in
  properties. Every system is singly designed for
  the building during which it's visiting be put
  in. each side of the building and its contents is
  taken into account within the style. But, to know
  a sprinkler system, we want to get back to
  basics.
• The Water Supply
• A sprinkler system is completely dependent on its
  water supply. The water supply will vary from a
  affiliation to the citys main to the
  installation of tanks and large pumps. For the
  aim of this text, we are only going to deal with
  the citys main supply.

• The citys main supply the water to the system
  via a suitably sized connection. This connection
  is normally device at the purpose of connection
  in order that it are often isolated if the need
  arises. The size of this connection is decided by
  the flow and pressure needed for the right
  operation of the system. This is often determined
  by the hydraulic style - more on that later.
• It goes while not saying that the water supply is
  that the most important a part of a fire
  sprinkler system - no water supply, no fire
  sprinkler system.
• I have been concerned within the style of various
  fire sprinkler systems over my forty years within
  the industry and it all starts with the water
  supply. The primary issue to determine before you
  proceed with either the design or installation is
  that the quality of the water supply. Ive got
  known of instances once systems couldn't be put
  in because the water supply wasn't sufficient and
  wasn't capable of being improved by the use of
  pumps, reservoirs etc.
• The control Valve Set
• Once you have the water supply to the building
  you need a control valve set.
• This contains another isolation valve for the
  purpose of quickly shutting them down the system
  within the event of a false activation or after a
  real activation in order to allow the system to
  be reset. It also allows for the system to be
  shut down for maintenance purposes.

• At this point, there is also an alarm valve which
  is a modified check valve. This serves the
  purpose of keeping the system charged with water
  and, owing to its special design, allowing for a
  hydraulic gong (water motor alarm) to activate
  when the system operates. This gives a local
  warning of the activation.
• Located on this alarm valve is a large drain port
  (which is also valved) which allows the system to
  be drained as and when necessary.
• We also have a DBA (Direct Brigade Alarm) which
  is an electrical device that monitors the state
  of the Fire Sprinkler System. It notifies the
  fire brigade when the system activates and also
  has a defect function that warns the service
  agent of any pressure drop or other potential
  problems.
• If the system is controlled above towns main
  pressure then there will also be a small system
  booster pump. There are also many other smaller
  accessory valves.

• The installation consisting of pipes and
  sprinklers
• Above the control valves, the system covers the
  entirety of the building with pipe and sprinkler
  heads. Each pipe is hydraulically calculated to
  make the most of the available water supply. The
  pipe weaves from the valves to its final point in
  varying sizes. The larger pipes are called mains
  and the smaller pipes are called ranges.
• Each pipe is supported with seismically designed
  supports to maximize its ability to face up to
  earthquakes and other destructive forces.
• There are now many alternative types of sprinkler
  heads and these need to be selected carefully to
  make sure they will do the necessary job. For
  instance, a sprinkler in an office may look, and
  act, dramatically different from one in a storage
  warehouse.
