Fire extinguishing system
First Claim
1. 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;
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; and
a water shutoff control connected to the pipe fitting, for shutting off water flow from said fire extinguisher sprinkler head when a predetermined condition is met.

Abstract
A fire extinguishing system is adapted particularly for incorporation with a clothes dryer in a home laundry area, for extinguishing any fire occurring from ignition of lint or other combustible material. The system may also be installed with other large, heat producing appliances (kitchen stove, etc.) for extinguishing any fire resulting therefrom. The system includes one or more conventional, heat activated fire extinguisher spray heads connected to the main water line of the structure. Each extinguisher head is secured in a fitting including an automatically actuated water shutoff valve, which closes after the fire has been extinguished to reduce water damage to the surrounding area. The system also includes an automatic disconnect or shutoff for at least the electrical circuit associated with the appliance which causes activation of the extinguisher head, and may further include an automatically actuated local (household) and/or distant (fire department) alarm.
