Abstract: Fire fighting apparatus has a fire retardant or fire quenching system mounted on a structure operative in response to detection of fire to take water from a reserve supply in the absence of main water line or supply flow or pressure. The reserve supply may be a reservoir such as a pool or it may be unpressurized water in the main water line. Detection is achieved via remote temperature or smoke sensors as examples as well as remote actuators such as telephone or portable signal transmitting units. Power is supplied by battery connection to motors, pump, and relays for oprating the apparatus and valves are selectively disposed in an interconnecting pumping network with the pump and motor to conduct water from the reserve supply.
