This diagram shows the progression of a fire over time. Note that the incipient stage of a fire provides the widest window of opportunity to detect and control
the spread. VESDA detectors can be configured to generate multiple alarms within the incipient stage. They also can be configured to generate an additional
alarm (Fire 2) in the advanced stages of a fire. This feature is unique to VESDA and takes advantage of its wide sensitivity range that enables one detector to
monitor the entire progression of a fire.
