Who invented a fire sprinkler system to protect his piano factory?
Henry Parmalee.
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.
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.
Will you get a discount on homeowners insurance if you install a sprinkler system?
=== === If its a yard sprinkler, no. If its a fire sprinkler, yes.
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.
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.
How long before a water motor gong should go off in fire sprinkler system?
A water gong is typically arranged to alarm the instant water in the sprinkler system begins flowing, certainly within a few seconds, as the pressure drops on the sprinkler side, allowing water pressure to turn the clapper in the gong.
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.

Which type of fire sprinkler system is installed wherever the system is subject to freezing?
To avoid problems of freezing water and broken pipes, a "dry sprinkler" system can be installed. The sprinkler heads can be sealed shut with temperature-sensitive valves, as in most wet systems, but the pipes are put under air pressure instead of water pressure, until one of the heads is activated by a fire. Water rushes into the system and sprays out of the open sprinkler head(s) within seconds, if all goes according to plan.
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 in the piping of a dry sprinkler system?
Normally it is filled with compressed air. A dry sprinkler system is used in areas exposed to temperatures that would freeze water. When a fire is sensed the soft metal link of a sprinkler head melts , releases the compressed air which in turn opens a valve to a fire main allowing the system to flood with water and extinguish the fire. Parking ramps in the northern US have dry systems, for example, because of the weather.
