Fire Sprinkler system

Fire Sprinkler SystemWhat is Fire Sprinkler System?
A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected.
It was used only in factories and large commercial buildings in past.
In recent times, systems for homes and small buildings are available at a cost-effective
price.
Sprinkler systems save lives in the event of a fire. Along with other active and passive fire
protection measures, a well-maintained fire sprinkler system installation can help suppress
smoke and flames, and lessen the spread of the fire, reducing damages and giving
everyone time to exit the building safely while fire services arrive.
Types of Fire Sprinkler System
There are four main types of commercial fire sprinkler services, each adapted to the needs of various facilities to maximize response time and ensure the protection
of employees and assets.
Wet Pipe System
Wet sprinkler systems—or traditional fire sprinklers—are the most common across
residential and commercial buildings. When a fire begins, the heat activates the
nearest sprinkler head, releasing pressurized water stored in the pipes. Each sprinkler
head is activated independently, reducing water damages in the event of a false alarm.
Wet pipe systems are an inexpensive, low-maintenance option appropriate for offices,
schools, and commercial properties.
Dry Pipe System
As opposed to wet pipe systems, dry pipe systems do not store water in their pipes.
Instead, they are filled with pressurized air or nitrogen, which is released if a fire
activates the valves in the sprinkler head. The pipes then fill with water and discharge
it over the smoke or flames. While this system is more complex and costly than a wet
pipe system, it is the most appropriate for cold climates where there is a high risk of
frozen pipes halting an emergency fire response.

Pre-Action System
Pre-action systems are another form of dry pipe sprinkler, but require a two-step
activation. When heat or smoke is detected, the pre-action valve will open and allow
water into the pipes. Then, sprinkler heads can be individually activated to release
water over the fire. This two-step process enables facilities to shut off the system in
case of a false alarm, protecting their assets from water damage. Pre-action systems
are especially useful in places where accidental discharge could lead to irreparable
damages, such as museums, libraries, and data centers.

Deluge System
Deluge sprinkler systems are another version of a dry pipe system. However, as
opposed to all previous options, the sprinkler heads in this system are always open.
They do not have a heat-sensing element in the sprinkler head itself, and require an
external smoke or heat sensor to activate. Once heat is detected, water fills the pipes
and is released to all open sprinkler heads, creating a flooding effect across the entire
area. This system is most often used in industries with flammable liquids that are likely
to spread rapidly.
