Abstract
Abstract An intrusion detection system used to surveil a predetermined space includes a monitor disposed within the space and a remote controller. The monitor contains an intrusion detector for sensing an intruder in the space and a memory circuit for recording any sensed intrusion. The remote controller includes an RF transmitter activated by a button switch the timed closure of which arms the monitor and the pulsed closure of which tests the monitor. The monitor produces an audible or a visual output in response to a test RF signal transmitted by the remote controller to indicate that an intrusion has not occurred. A pulsed closure of the button switch while the monitor is producing the output disarms the monitor. Should the monitor detect an intrusion and/or be disabled by the intruder, the lack of the monitor output in response to the test RF signal transmitted by the remote controller warns a returning occupant, before entering his or her premises, there exists the possibility of confronting an intruder.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
An improved intrusion detection system of the type in which an intrusion is detected by a monitor having an RF receiver, a power supply, an intrusion detector, a logic circuit, a memory circuit, and a responder, and in which said monitor is disposed to surveil a predetermined space, and in which said monitor has an armed state and a disarmed state and a user employs a hand held RF remote controller to arm and disarm said monitor, wherein the improvement comprises: said remote controller having a button switch for generating a code signal under the control of said user; said monitor being armed by said code signal of a predetermined duration from said remote controller; said state of said monitor being tested by said code signal from said remote controller of a duration less than said predetermined duration; and said monitor being alternatively disarmed by either of said code signal from said remote controller when said responder is responding and the sensing of a power interruption by the logic circuit.
Claim 2
Dependent Claim
170 words
An improved intrusion detection system of the type in which an intrusion is detected by a monitor having an RF receiver, a power supply, an intrusion detector, a logic circuit, a memory circuit, and a responder, and in which said monitor is disposed to surveil a predetermined space, and in which said monitor has an armed state and a disarmed state and a user employs a hand held RF remote controller to arm and disarm said monitor, wherein the improvement comprises: said remote controller having a button switch for generating a code signal under the control of said user; said monitor being armed by said code signal of a predetermined duration from said remote controller; said state of said monitor being tested by said code signal from said remote controller of a duration less than said predetermined duration; and said monitor being alternatively disarmed by either of said code signal from said remote controller when said responder is responding and the sensing of a power interruption by the logic circuit.
Claim 3
Dependent Claim
27 words
The improved intrusion detection system according to claim 1 wherein said code signal is transmitted by holding said button switch closed for a short period of time.
Claim 4
Dependent Claim
35 words
The improved intrusion detection system according to claim 1 wherein said code signal is transmitted by a momentary closure of said button switch thereby producing a response from said responder if said monitor is armed.
Claim 5
Dependent Claim
22 words
The improved intrusion detection system according to claim 1 wherein said power interruption is caused by said intrusion detector detecting said intrusion.
Claim 6
Dependent Claim
41 words
The improved intrusion detection system according to claim 1 wherein said code signal from said remote controller is caused by a momentary closure of said button switch thereby disarming said system when said responder is responding to an earlier transmitted signal.
Claim 7
Dependent Claim
22 words
The improved intrusion detection system according to claim 2 wherein said short period of time is preferably between three and seven seconds.
Claim 8
Dependent Claim
20 words
The improved intrusion detection system according to claim 3 wherein said momentary closure is preferably between one and two seconds.
Claim 9
Independent Claim
182 words
A method for operating an intrusion detection system, said detection system comprising a remote controller and a monitor, said remote controller having a button switch, said monitor including a memory circuit having an armed and a disarmed state, said controller remotely arming, disarming and testing said memory circuit, said monitor having means for detecting and reporting an intrusion in a predetermined space, said method comprising the steps of: a. arming said self-contained monitor by closing said remote controller button switch for a short period of time; b. testing said monitor by a momentary closure of said button switch, thereby producing a test response from said monitor when armed; c. monitoring said predetermined space to detect an unauthorized entry; d. triggering said monitor from said armed state to said disarmed state in response to said unauthorized entry; e. testing for an intrusion by a momentary closure of said switch to obtain a signal response from said self-contained monitor provided said intrusion has not occurred; and f. disarming said self-contained monitor by a momentary closure of said button switch while said responder is responding.
Claim 10
Independent Claim
182 words
A method for operating an intrusion detection system, said detection system comprising a remote controller and a monitor, said remote controller having a button switch, said monitor including a memory circuit having an armed and a disarmed state, said controller remotely arming, disarming and testing said memory circuit, said monitor having means for detecting and reporting an intrusion in a predetermined space, said method comprising the steps of: a. arming said self-contained monitor by closing said remote controller button switch for a short period of time; b. testing said monitor by a momentary closure of said button switch, thereby producing a test response from said monitor when armed; c. monitoring said predetermined space to detect an unauthorized entry; d. triggering said monitor from said armed state to said disarmed state in response to said unauthorized entry; e. testing for an intrusion by a momentary closure of said switch to obtain a signal response from said self-contained monitor provided said intrusion has not occurred; and f. disarming said self-contained monitor by a momentary closure of said button switch while said responder is responding.
