Abstract

A management system for controlling the dispensing of a fire fighting agent from a container in which a control device is used to select a desired rate of discharge of a fire fighting retarding agent from a container. The system includes a display in visual proximity to a user of the control device for visually indicating the selected flow rate of the fire retarding agent from the container. In addition, the system includes a visual display for indicating the time remaining, preferably in minutes and seconds, for the fire retarding agent in the container to be substantially completely expended. Alternatively, a synthesized voice may announce the time remaining at predetermined intervals such as every 5 seconds. Finally, a visual display, preferably in the form of a bar graph, gives the real time physical level of the fire retarding agent remaining in the container at any given time.
