What is usage of Jacky pump in fire system?
Did you mean Jockey Pump which is a small pump connected to a fire sprinkler system and intended to maintain pressure in a fire protection piping system to an artificially high level so the operation of a single fire sprinkler will cause a drop in pressure that will be sensed by the fire pumps automatic controller, causing the fire pump to start. The Jockey Pump is essentially a portion of the fire pumps control system.

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.
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.
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.
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 creates water pressure in the house?
High water pressure from the street or well, but there's an exception: City water pressure (from the street) may need to have the pressure reduced to the home. Some homes have pressure regulators for this purpose, some do not. The same goes for well systems that use a pressure pump (an often a pressure tank); the outlet pressure is set so that the pressure to the home doesn't go too high or too low. An exception for homes with fire sprinkler systems. There is a check valve from the main water supply that feeds the fire sprinkler system. As temperatures drop at night, the water in the fire sprinkler pipes contracts slightly and additional water from the main water line goes into the fire sprinkler system. During the day, the water in the fire sprinkler pipes heats up and expands slightly, but has no where to go because of the check valve. This action can cause a very high pressure in the fire sprinkler pipes if there isn't also a pressure relief valve in the system. Numerous older homes do not have a pressure relief valve for the fire sprinkler system and risk having a pipe or joint burst. The bottom line: if you suspect that you have high water pressure in the home, consult a local plumber or building contractor for the appropriate solution.

How do you add zones to a fire sprinkler system?
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.
Which type of fire sprinkler system is most common and easiest to install?
Wet pipe sprinkler
What other country aside from the US is noted for its interest in developing the automatic fire sprinkler system?
England is noted for its interest in developing the automatic fire sprinkler system.

68 degree centigrade needs to break the red bulb in the fire sprinkler.
