Abstract
An intrusion detection system includes a remote controller activated by a user transmitting a particular RF carrier signal to a self-contained monitor. The self-contained monitor is energized by a primary power source and comprises an RF receiver circuit for receiving the particular RF carrier signal, a tuning code circuit for inputting a tuning code, a nonvolatile memory circuit for storing the tuning code which makes the RF receiver circuit responsive to the particular RF carrier signal, a volatile memory circuit having an armed state and a disarmed state, a motion detector for detecting an intruder in the predetermined space, a timing circuit for measuring a preset period of time and a responder. The user switches the volatile memory circuit from the disarmed state to the armed state by activating the remote controller. The volatile memory circuit is switched from the armed state to the disarmed state by either the volatile memory circuit sensing an interruption in primary power lasting longer than the preset period of time or by the motion detector detecting an intruder. The user tests the state of the volatile memory circuit by manipulating the remote controller to prompt a response from the responder indicating whether the volatile memory circuit is in the armed state or the disarmed state. A response indicating that an intrusion event has occurred warns the user not to enter the predetermined space to avoid the possibility of inadvertently confronting a remaining intruder.
