Abstract:
An intrusion detection system comprising:a self-contained monitor energized by a primary power source responsive to a remote controller transmitting a particular RF carrier signal under the control of a user; said self contained monitor including a nonvolatile memory circuit storing a tuning code therein, a tuning code circuit for inputting said tuning code communicating with said nonvolatile memory circuit, a transfer switch communicating with said nonvolatile memory circuit and with said tuning code circuit, an RF receiver circuit communicating with a motion detector, a volatile memory circuit, a responder, and with said nonvolatile memory circuit; said motion detector surveiling a predetermined space for an intruder; said transfer switch being manually activated by said user transferring said tuning code from said tuning code circuit to said nonvolatile memory circuit; said RF receiver circuit being made responsive to said particular RF carrier signal by said tuning code stored in said nonvolatile memory circuit; said volatile memory circuit selectively defining an armed state and a disarmed state; said volatile memory circuit being selectively disarmed by sensing at least one of an interruption of primary power and said motion detector detecting an intruder; and said responder being prompted by said RF receiver circuit responding to said particular RF carrier signal to generate a response indicating one of said states of said volatile memory circuit.
