Abstract

A fire suppression system having a plumbing assembly, an engine, a hose, an air-bleed valve, and a controller is provided. The controller includes a one-touch activation control. The controller is also configured to automatically activate the air-bleed valve to remove air within the hose to prevent user injury and damage to the fire suppression system. A fire suppression system that automatically configures the fire suppression system to output a predetermined fire suppression fluid composition upon actuation of a one-touch activation control is also provided. In addition, an integrated control system is provided to automatically configure a fire truck'"'"'s interlock and shift pump operation.

Claims

1. A fire suppression system comprising:

a plumbing assembly that includes;

a water tank,

a pump having an input and an output in fluid communication with the water tank,

a master intake valve in fluid communication with the input of the pump, and

a one-way check valve in fluid communication with the water tank, the pump, and

the master intake valve and being located between the water tank and both the pump and the master intake valve;

an engine for driving the pump;

a hose that includes;

a second end, and

a first end for connecting to a water supply;

an air-bleed valve in fluid communication with the hose and the master intake valve and positioned between the second end of the hose and the master intake valve, the air-bleed valve including a level sensor for detecting the presence of air within the hose; and

a controller operatively connected to the air-bleed valve, the engine, and the pump, the controller including a one-touch activation control to activate the controller,

wherein the controller is configured to activate the air-bleed valve to remove air from the hose and to prevent increases in pump pressure by the pump by preventing the engine from increasing engine speed when the controller receives a signal from the air-bleed valve indicating the presence of air within the hose.

2. The fire suppression system of claim 1, wherein the plumbing assembly further comprises a tank-to-pump valve in fluid communication with the water tank and the one-way check valve and positioned between the one-way check valve and the water tank to control a flow of water out of the water tank to the pump.

3. The fire suppression system of claim 2, wherein the plumbing assembly further comprises a tank-fill valve in fluid communication with the output of the pump and the water tank to control a flow of water from the pump into the water tank.

4. The fire suppression system of claim 2, wherein when the level sensor detects the presence of air within the hose, the controller is configured to open the master intake valve, close the tank-to-pump valve and fill the water tank.

5. The fire suppression system of claim 1, wherein the controller further includes:

an air-bleed valve toggle knob configured to operatively control the air-bleed valve so as to enable a user to selectively open and close the air-bleed valve to varying degrees; and

an air-bleed valve auto knob configured to operatively control the air-bleed valve in either an open or a closed position.

6. A method of bleeding air from a hose for a fire suppression system that includes a plumbing assembly having a water tank and a tank-to-pump valve in fluid communication with the water tank, a pump in fluid communication with the tank-to-pump valve and the water tank, a master intake valve in fluid communication with the pump, an engine for driving the pump, an air-bleed valve in fluid communication with the master intake valve, the air-bleed valve including a level sensor, and a hose in fluid communication with the air-bleed valve, comprising the steps of:

providing a controller that includes a one-touch activation control to activate the controller, wherein the controller is operatively connected to the air-bleed valve, the engine, and the master intake valve;

actuating the one-touch activation control to activate the controller;

sensing the presence of air within the hose by the level sensor;

signaling the controller of the presence of air sensed within the hose by the level sensor;

outputting a command signal from the controller to open the air-bleed valve to bleed air upon receiving the signal sensing the presence of air within the hose; and

outputting a command signal from the controller to the engine to halt increases in engine speed to prevent increases in pump pressure upon receiving the signal sensing the presence of air within the hose.

7. The method of claim 6, further comprising the steps of outputting a command signal from the controller to open the master intake valve, close the tank-to-pump valve and fill the water tank.
