Fire-fighting control system

A method of controlling a fire-fighting device including a pump, said method comprising:

• receiving, at a controller, a first pressure signal from a first pressure sensor coupled to a nozzle, the first pressure signal indicative of a first fluid pressure of a fluid at the nozzle;
• receiving, at the controller, a second pressure signal from a second pressure sensor located remote from the first pressure sensor, the second pressure signal indicative of a second fluid pressure of fluid at a discharge valve that controls fluid flow between the pump and the nozzle;
• controlling operation of at least one of the pump and the discharge valve based on a user-requested fluid pressure and the first pressure signal in a primary mode of operation;
• and
• controlling operation of the at least one of the pump and the discharge valve based on the user-requested fluid pressure and the second pressure signal in a secondary mode of operation when signal communication between the first pressure sensor and the controller is interrupted.

A controller for use with a fire-fighting device including a pump, said controller configured for communication with a first pressure sensor coupled to a nozzle, said controller further configured for communication with a second pressure sensor located remote from the first pressure sensor, said controller configured to:

• receive a first pressure signal from the first pressure sensor, the first pressure signal indicative of a first fluid pressure of a fluid at the nozzle;
• receive a second pressure signal from the second pressure sensor, the second pressure signal indicative of a second fluid pressure of fluid at a discharge valve that controls fluid flow between the pump and the nozzle;
• control operation of at least one of the pump and the discharge valve based on a user-requested fluid pressure and the first pressure signal in a primary mode of operation;
• and
• control operation of the at least one of the pump and the discharge valve based on the user-requested fluid pressure and the second pressure signal in a secondary mode of operation when signal communication between the first pressure sensor and the controller is interrupted.
