Fire extinguishing system

A fire extinguishing system for installing with an electrical device receiving electrical power from an electrical circuit having at least one electrical circuit protective device therein, the system comprising:

• a pipe fitting having an inflow end and at least one outflow end;
• a fire extinguisher sprinkler head installed to said at least one outflow end of said pipe fitting;
• a water flow sensor communicating with said inflow end of said pipe fitting, for transmitting an electrical signal when water flows through said pipe fitting;
• and
• an electrical circuit shutoff electrically communicating with said water flow sensor, for disconnecting electrical power to the electrical device when water flow occurs through said pipe fitting.

A fire extinguishing system for installing with an electrical device receiving electrical power from an electrical circuit having at least one electrical circuit protective device therein, the system comprising:

• a pipe fitting having an inflow end and at least one outflow end;
• a fire extinguisher sprinkler head installed to said at least one outflow end of said pipe fitting;
• a water flow sensor communicating with said inflow end of said pipe fitting, for transmitting an electrical signal when water flows through said pipe fitting;
• and
• a water shutoff control, for shutting off water flow from said fire extinguisher sprinkler head and including:
• a valve disposed in the pipe fitting;
• and
• one of a timer control connected to the valve for shutting off water flow from said fire extinguisher sprinkler head after a predetermined elapsed period of time has passed or at least one fire sensor connected to the valve for shutting off water flow from said fire extinguisher sprinkler head after the fire has been extinguished.
