Fire sprinklers have two major components that operate in response to a fire: the fire sprinkler heads which are connected via a series of pipes to a fire pumps. Water pressure is kept in the head by a series of valves in the pump. and is kept in the heads by little vials of colored liquid.
During a fire, the liquid inside the sprinkler heads heats up and starts to expand, eventually causing the vial to burst. Water that was kept in the pipes pours out of the sprinkler heads.
The water pouring out of the sprinkler heads causes the pressure in the fire pump to drop. In response, the pump kicks on and pumps more water from the municipal water supply to keep the sprinkler flowing.
NOTE: this is how "wet pipe" fire sprinklers, the most common types of fire sprinklers, work. Other sprinklers (dry pipe, deluge and pre-action) are slightly different.

What types of liquid in sprinkler?
Sprinkler systems used in buildings to put out fires quickly use water.
What are the reasons for fire sprinkler systems?
Fire sprinklers are used to protect buildings from fires by dousing them with water provided by a fire pump. Water fights fire by removing the heat, cooling down burning surfaces and interrupting the combustion process.
Why do sprinkler systems use wax plugs?
I'm guessing it's because wax melts with heat i.e. fire and so allows a path for water to exit the sprinkler and put out the fire.
How would put out a fire on a jumbo jet?
How big of a fire is it? If it's a small fire, like a trash can or something, airliners have handheld fire extinguishers. For an engine fire or a cargo compartment fire, airliners have fixed fire suppression systems--the plane has plumbing, sprinkler heads and tanks of fire extinguishing agent. But those huge fires you see when a plane crashes? Aircraft crash fires are primarily fuel fires--Class B. The best agent is Aqueous Film Forming Foam, or AFFF, which was invented by the US Navy to fight fires on aircraft carriers. It works extremely well.
What is a quick response fire sprinkler?
A quick response fire sprinkler is a fire sprinkler designed to react immediately upon sensing a fire. Typically quick response fire sprinklers are heat activated, where heat from a fire melts a fusible link that allows the fire extinguishant (usually water in the case of fire sprinklers) to put out the fire quickly. Fire sprinkler systems are an important part of a building's total fire protection system, which should also include fire alarms, fire extinguishers and, where appropriate, specialized fire suppression systems.
How do you put fluid in the fire sprinkler?
Fire sprinkler systems are either fed directly from city water mains or from a private cistern (often seen on roofs of old buildings), perhaps with a fire pump run from an internal combustion engine or electric with generator backup.
What does deluge mean in a fire sprinkler system?
A deluge fire sprinkler system, unlike most ordinary systems, mean that the sprinkler heads do not have individual heat-sensitive valves. The sprinkler heads in a deluge system have no valves of their own, meaning they are always open and water will be sprayed out of them when the supply valve is turned on. There are limited uses for deluge systems, such as in a tire storage warehouse where it is important to put out a fire quickly and the massive flow of water will not cause major damage.
Will all types of fire extinguisher bottles put out all categories of fires?
Not all fire extinguishers will put out all fires. You must check your fire extinguisher to make sure that is equipped for all fires since different fires must be put out different ways.
What is the purpose of the fire extinguisher?
To put out a fire...
What does a fire services officer do?
put out fires
Where can I find a reasonably priced company that installs residential sprinkler systems?
I currently do not have a sprinkler system and am wanting to put a system in. Where can I find a company that will put in a system for me at a reasonable price?
What should you put on a fire?
You should put different things on a fire depending on what is causing the fire. Water is good for fires with nonmetallic combustible sources such as paper or wood. For electrical, grease, or metallic fires you will need fire extinguishers made for those types of fires.
