Abstract
A intruder detection system is described comprising a programmable alarm control panel capable of issuing an alarm signal representative of an intruder in a protected zone wherein the control panel is electrically coupled to a plurality of sensors by both a commonly connected status line and individual zone signaling lines between the panel and each sensor. The control panel is capable of providing distinct status information to each sensor to which it is coupled thereby permitting each individual sensor in the loop to be separately operational based on its own status as active or bypassed. For instance, if the sensor of zone 1 is active it can be set to an appropriate stability level for intrusion detection; alternatively, if, at the same time, the sensor associated with zone 2 is bypassed, it can be set to operate as a high sensitivity occupancy detector. The intruder detection system of the present invention utilizes status signals which individually identify and set each sensor.
