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.

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.
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.
=== === If its a yard sprinkler, no. If its a fire sprinkler, yes.
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.
Yes, you can determine if the fluid in a glass bulb fire sprinkler is appropriate by visually inspecting the bulb for any signs of damage or leakage. The liquid inside the bulb should be at a specific level, typically indicated by a mark on the bulb itself. Additionally, manufacturers often provide specifications regarding the fill volume, which can be compared against the measured amount if the bulb is tested or replaced. If in doubt, it is best to consult with a fire protection professional or replace the sprinkler.
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.
modern automatic sprinklers use a glass bulb that is filled with a fluid that boils and expands at a preset temperature. the glass bulb has a small bubble in the fluid. when a fire causes the fluid to boil, it shatters the glass bulb, which is keeping the waterway seal of the sprinkler in place. When the seal is gone, water can flow through the sprinkler orfice, and extinguish the fire. older sprinkler models use a link and lever arrangement, with a link of solder that melts at a preset temperature. The link and levers of the sprinkler mechanically hold the waterway seal of the sprinkler closed. When the link melts, the mechanical seal is gone, and water can flow through the orfice.
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.
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.
68 degree centigrade needs to break the red bulb in the fire sprinkler.
