ABSTRACT:
A fire extinguishing system for a Christmas tree including a base defining a water reservoir and having a submersible pump and container holding a fire extinguishing foam material mounted in the reservoir. A venturi block mixes the fire extinguishing foam material with water pumped from the reservoir upon detection of a fire condition by sensors scattered throughout the tree which mixture is discharged through a spray head mounted at the top of the tree. A relay connected to the fire sensors simultaneously closes an electric circuit to the pump and opens an electric circuit to the Christmas tree lights when the fire condition is sensed.
