A fire alarm system for graphically illustrating a fire alarm event is provided. The fire alarm system may receive fire alarm information from one or more fire sensors in a building, and may determine a rate of change of at least one aspect of the fire sensor. The rate of increase of temperature, the length that the fire sensor has been activated, the progression of the fire, etc. The rate of change may be graphically illustrated to enable the operator to quickly assess the fire alarm event. A fire alarm system, whose actions are modified by the rate of change of the fire alarm event, is also provided. Depending on the rate of change, one or more input devices (e.g., cameras or other sensors) one or more output devices (e.g., sprinklers, notification appliances, etc.) in the fire alarm system may be controlled.
