Abstract
A method of indicating a degree of incoming threat to an electronically secured area consists of the steps of sensing via sensor a degree of threat delivered to a secured area and generating an electric signal proportional to the degree of threat; analyzing the signal to determine if it is a low degree of threat or a high degree of threat; and producing either a first pulse representing low degree of threat or separately producing the first pulse and a second pulse representing a signal having both low degree of threat and high degree of threat.
