Standard wet-pipe fire extinguishers (the kind that you'll find in most buildings) have 2 components: the fire pump and the pipe system. Within the pipes there is pressurized water, held in place by the sprinkler heads. This water is supplied to the pipes by the fire pump.
If you look carefully at a fire sprinkler head, you'll notice what appear to be glass bulbs filled with a colored liquid. The liquid in these bulbs is extremely heat sensitive, and the heat from a fire in the building will cause it to expand and burst the bulb. This releases the pressurized water from the pipes into the room with the fire. Another type of sprinkler valve uses a "fusible link" that is calibrated to melt and open the valve when it is hot enough.
The release of water by the sprinkler head causes a drop of water pressure in the fire sprinkler system, which sends a signal to the fire pump that it needs to kick on and supply more water pressure to the sprinklers so they can continue to put out the fire. Once the fire is extinguished, the only way to turn the sprinklers off is to shut them off at the pump. This is usually only done with permission of the fire department.
Some fire sprinklers work by turning on the whole system at the signal of smoke or fire and dousing the entire area with water.
Fire sprinklers are often found in public buildings. They are connected to smoke detectors, so when the detectors go off, the fire sprinklers do as well.

The glass tube in a fire sprinkler expands less than the liquid inside the tube when exposed to heat. This difference in expansion causes the glass tube to break and activate the sprinkler system in the event of a fire.
Yes, the size of the hole in a spinning sprinkler can affect how fast the sprinkler will spin. A larger hole will allow more water to flow out, increasing the force that drives the rotation of the sprinkler. Conversely, a smaller hole will reduce the force and may result in a slower spinning speed.
The most common types of liquid used in sprinklers are water and foam. Water is the primary liquid used for fire suppression, while foam is often used for flammable liquid fires and in locations where water may cause damage. Additionally, some sprinkler systems may use other liquids such as dry chemicals for specific fire hazards.
Not quite. Heat is a result of combustion, but fire is actually chemical energy.
Fire, all fire, every fire consists of 3 things: Heat, Fuel & Oxygen. When all 3 are together in the right mix you have fire, if one or more elements is not sufficient then you cannot have fire. You therefore need as much heat as necessary along with the fuel & oxygen to maintain the fire. The specific answer is that the balance of the 3 must be correct. Quantifying that, however, is a different matter.
Since hot air is lighter than cool air, heat, especially the high heat from a fire, moves up to the fire sprinkler heads on the ceiling the ceiling rapidly. When the heat gets too great, heat sensitive bulbs contained in the sprinkler heads burst and release pressurized water from behind the bulbs.

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.
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.
Automatic Sprinkler of Connecticut LLC specializes in the simplest and most cost-effective types of automatic fire sprinkler systems, wet pipe sprinklers. Wet pipe sprinklers are the most common type of sprinkler system and are very reliable. They use water from a pressurized supply line to activate the sprinklers in case of smoke or heat detection, quickly suppressing any fires while minimizing damage.
=== === If its a yard sprinkler, no. If its a fire sprinkler, yes.
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.
Fire sprinkler systems are effectively already zoned - you don't need to do anything special. When your fire sprinkler system detects a fire, it doesn't set off all the sprinkler heads at once. Instead, each fire sprinkler head goes off when the temperature underneath it reaches a specific temperature, meaning only the ones affected by the fire will go off.
A sprinkler bell valve in a fire protection system controls the flow of water to sprinkler heads. It opens when the system detects a fire, allowing water to flow and extinguish the fire.
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.
The maximum distance between fire sprinkler, per NBC, depends on the sprinkler system. The size of the sprinkler and the number of sprinklers need to be considered when installing.
Most standard fire sprinklers are activated by heat. There's a small bulb of liquid that keeps the water back in the pipes before a fire begins. When a fire breaks out, that liquid will heat up and eventually cause the bulb to burst, releasing the water from behind it.
