Fire sprinkler systems: a guide to designs, colour codes and suppliers


Take a gander at the roof of any open building and you’ll see that fire sprinkler systems are all around. To the untrained onlooker, one sprinkler framework is likely particularly the same as another.

Despite what might be expected, there are a few distinct kinds of fire sprinkler systems. Indeed, even the extinguishant shifts as indicated by the building’s condition and temperature settings. Every arrangement is shading coded.

The sprinkler framework we know about today has its underlying foundations in Hiram Stevens Maxim’s nineteenth century plan. After its patent ran out, Henry S Parmalee went up against the outline in 1874 to secure his piano processing plant. For more visit nyc sprinkler code.

Unexpectedly, as opposed to being known for fire sprinklers, Hiram Stevens Maxim’s greatest commitment to building was the ‘flying machines’ ride at Pleasure Beach Blackpool from 1904.

Back to present day sprinkler systems: there are eight diverse shading codes and eight assortments of sprinkler taps. This article expects to give you a straightforward reference direct.

Sprinkler tap plans

The eight kinds of sprinkler taps:


Flat sidewall

Vertical sidewall

Recessed pendant

Covered pendant



Covered even sidewall

A sprinkler tap as most laypersons would remember them would be the ordinary, upright variants. Traditional systems have a round arrangement of circulation which focuses to the ground like a shower head.

Also outlined, however with spouts pointing downwards, pendant sprinkler systems work comparably, yet are recessed, disguised and less nosy.

The covered pendant tap is circumspect, with a confuse to veil the spout. They are prevalent in workplaces and open structures.

Flat and vertical sidewall sprinklers (counting covered level sidewall forms) have a larger number of capacities than standard sprinkler systems.

Sprinkler shading codes

And also the spout, another key piece of any sprinkler framework is the knob. The globule can change in thickness. Hues fluctuate as per temperature settings, as point by point in the table underneath.

The shading codes seen above identify with the glass globule shading. Normal sprinkler systems have orange or red knobs. Halfway, yellow or green. High temperature globules are hued in blue up to 246 degrees Celsius, at that point purple up to 302 degrees Celsius, and dark for anything above. These fall in the Very Extra High and Ultra High classifications.

Sorts of fire sprinkler systems

There are four principle sorts of fire sprinkler systems which are in like manner utilize:

Wet Pipe;

Dry Pipe;



Wet Pipe

Wet Pipe sprinkler systems are the most widely recognized sort of sprinkler systems being used. They are found in workplaces and houses and are purported, as the water-based extinguishant is put away under strain in its funnels. Enactment is prompt.

Dry Pipe

Where funnels are probably going to solidify, dry pipe sprinkler systems are a contrasting option to the standard wet pipe systems. Nitrogen gas or pressurized air is put away in the channels, which are enacted before being trailed by water. Not at all like its wet pipe counterparts, there is a slight deferral.


Storm sprinkler systems are regularly utilized as a part of regions where quick fire harm is a noteworthy concern. For instance, distribution center stacking coves and tall structure windows. They are comparable in configuration to wet pipe establishments however with one noteworthy distinction: the spout is constantly open. Another distinction is the means by which a downpour based sprinkler is activated. This is by means of an extraordinary alert that opens a water discharge valve.


The pre-activity sprinkler framework is a mix of wet pipe and dry pipe sprinkler systems. They are regularly utilized as a part of regions at high danger of water harm. Water isn’t put away in the funnels until a fire location framework distinguishes a fire. Right off the bat, the gadget opens a valve inside the funnels that discharges the water. This happens before the opening of the sprinkler heads. On opening, its reaction time is as quick as a standard wet pipe sprinkler framework.

Who makes fire sprinkler systems?

The world’s driving producer in fire sprinkler systems is Tyco Fire Protection Products. They are a multinational organization shaped in 1960 by Arthur J. Rosenberg with fire assurance and security items the pillar of their business. Their HQ is arranged in Cork, Republic of Ireland.

Another central maker is Wormald International. They are an Australian organization, whom at one time, were a backup of Tyco International. They were framed in 1889 by siblings, Joseph Dawson Wormald and Henry Percy Wormald. Both left Edinburgh for Australia to import Mather and Platt’s systems, fabricated in Newton Heath, Manchester. Subsequent to being a backup of Tyco, they were purchased by New York City based private value organization, Evergreen Capital, L.P. (Australia, Fiji) in 2016.

There is additionally various free organizations. A large number, situated in the UK, are individuals from the British Automatic Fire Sprinkler Association. The expert body was framed in 1974 and has affiliations with abroad bodies like the American Fire Sprinkler Association.
