The low melting point of a material used in automatic sprinkler systems helps it to quickly release water when exposed to heat, activating the sprinkler system. This property ensures rapid response and effective fire suppression.
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.
Cincinnati, Ohio, tackled this problem when it established the nations first paid fire department in 1853. By 1900, most cities had full-time professional fire departments. The introduction of the automatic fire sprinkler in 1874 and the replacement of wood as a building material with brick, stone, or concrete also made cities safer. Answer People had buckets on their upper floors to be used in case of fire. Not sure what the source of water would have been.

No, sprinklers in a deluge system are "open"; no valve in the sprinkler, and an automatic valve turns on the water to all open sprinklers when a fire condition is detected.
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).
water and no air Also, buildings can be designed with smoke and fire barriers to slow or completely stop the spread of fire and smoke. Heat-activated sprinkler heads can be used to douse a local fire and keep it from spreading. Automatic fire extinguishers are often used in dangerous processes (including commercial kitchens) to stop the spread of fire in the duct system or other hazardous materials.

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.
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.
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.
