ABSTRACT:
A visual display system detects and continuously displays the location of a breach in a protected building or secure area. Each of a plurality of exclusive OR gates is connected to a separate reed-type sensor switch. Each exclusive OR gate output is connected to a flip-flop network, each of which in turn is connected to a light emitting diode. Activation of a sensor switch results in lighting only of the light emitting diode associated with the area breached. A mechanism is also provided for preventing the generation of false alarms by transients or inadvertent momentary opening of any of the sensor switches.
