Abstract (en)
[origin: WO9635194A1] A method of indicating a degree of incoming threat to an electronically secured area comprising the steps of sensor (12) sensing 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 a 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, said pulses sent to an alarm control on a single conductor (85).
