Abstract

Claims (25)

1. A method of installing a foam proportioning system into existing fire fighting equipment, the method comprising:

installing a foam proportioning library into a first application of a processor of the existing fire fighting equipment;

installing a foam proportioning support into a second application of a display of the existing fire fighting equipment;

connecting a foam proportioner to the existing fire fighting equipment;

receiving user inputs with the display;

processing the user inputs with the second application and the foam proportioning support;

transmitting the user inputs to the processor;

operating the foam proportioner in response to the user inputs with the first application and the foam proportioning library.

2. The method of claim 1 and further comprising installing a foam proportioning library into a first application of a programmable logic controller of the existing fire fighting equipment.

3. The method of claim 1 and further comprising attempting to identify a valid foam proportioner and disabling the foam proportioning library and the foam proportioning support if a valid foam proportioner is not identified.

4. The method of claim 1 and further comprising operating an automatic start sequence.

5. The method of claim 4 and further comprising determining if a selected water pump is valid before operating the automatic start sequence.

6. The method of claim 4 and further comprising determining if enough foam additive is available before operating the automatic start sequence.

7. The method of claim 1 and further comprising obtaining a flow rate signal from a flow meter and a speed signal from the foam proportioner.

8. A foam proportioning system for installation into existing fire fighting equipment, the foam proportioning system comprising:

a foam proportioner for connecting to the existing fire fighting equipment;

a processor of the existing fire fighting equipment, the processor connected to the foam proportioner, the processor including a first application and a foam proportioning library; and

a display of the existing fire fighting equipment, the display including a second application and a foam proportioning support, the display receiving user inputs, the display processing the user inputs with the second application and the foam proportioning support, the display transmitting the user inputs to the processor;

the processor operating the foam proportioner in response to the user inputs with the first application and the foam proportioning library.

9. The system of claim 8 wherein the processor includes a programmable logic controller.

10. The system of claim 8 wherein the processor attempts to identify a valid foam proportioner and disables the foam proportioning library and the foam proportioning support if a valid foam proportioner is not identified.

11. The system of claim 8 wherein the processor operates an automatic start sequence.

12. The system of claim 11 wherein the processor determines if a selected water pump is valid before operating the automatic start sequence.

13. The system of claim 11 wherein the processor determines if enough foam additive is available before operating the automatic start sequence.

14. The system of claim 8 wherein the processor obtains a flow rate signal from a flow meter and a speed signal from the foam proportioner.
