MULTIPLE SENSOR INTRUSION DETECTION SYSTEM |
摘要 |
A multiple zone intrusion detection system in which a plurality of intrusion sensors can be readily converted into the system without system modification, and in which mode control signals from a central control unit and alarm signals from the sensors are both conveyed on a single conductor of the system cable. Each sensor has an associated interface module which permits coupling of different types of sensors to the system and sharing of a single conductor for mode control signals and alarm signals. |
