What is the most common extinguishing material used in fire sprinkler systems?
Ordinary water is used in most fire sprinkler systems. Most fire sprinkler systems are connected directly to the same water you get from the fire hydrant, which is also often the source for drinking water as well.

What is a sprinkler?
An irrigation sprinkler is a device that applies water to plants, mimicking the effect of rain, as it is done in lawn, garden and agricultural irrigation. A fire sprinkler is a device that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been reached.
Where can one find more information about fire sprinklers?
Over 40 million fire sprinkler heads are fitted each year. A fire sprinkler is a component of a fire sprinkler system that discharges water onto fires in the area once the effects of a fire have been detected, such as excessive increase in temperature.
What does a fire department connection do?
Fire department connections are actually used in fire sprinkler systems.When any fire occurs water is discharged from the sprinkler heads that have fused, and are discharging water to supress and extinguish the fire. The fire department connection is used by the fire department to add to the water supply to the sprinklers and/or charge the interior hydrant connection withn the building (if any).
What is the difference between deluge and other fire sprinkler systems?
In a deluge system the water comes out of all sprinkler heads at once, compared with most fire sprinkler systems in which each sprinkler head has its own heat-sensitive trigger. There are major design differences in how much water you need for a deluge system and what safety interlocks are built into the system to prevent accidental water damage.
How do fire sprinkler systems put out fires?
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.
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.
Why does a fire engine need to supply water to a fire sprinkler system?
A "fire department connection" (FDC) is often required on a sprinkler or standpipe system in case the ordinary supply of water fails to provide enough pressure for any reason. That way, a fire engine's pump can be used to pressurize the system with water from other sources.
What is a Fire Sprinkler alarm valve?
Some fire sprinkler systems have a valve for testing the water-flow alarm by allowing water to flow to the alarm, or through the alarm-sensing pipe, without activating any sprinklers in the rest of the system.
How much water does a wet pipe fire sprinkler spray per minute?
25-150 gallons per minute is standard depending on the type of sprinkler head. Residential sprinklers will be closer to 25. That flow is for a SINGLE sprinkler head. Typically the fire will be extinguished by just activating one sprinkler head.
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.
