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.
