Abstract

In a home security system, a microprocessor-based controller is responsive to user initiated keyboard entries for programming a plurality of remote sensors via a serial data link with sensor-unique data such as a sensor identification number and a house identification number. The thus programmed sensor may then be disconnected from and remotely located with respect to the controller for providing alert signals via an RF link to the controller upon triggering of the sensor. The programming data is also stored in the controller as well as in a central station to which a plurality of home-based controllers are coupled to provide the security system with a high degree of reliability.

Claims

1. In a security system including a plurality of remote sensors responsive to a sensory input from an area under surveillance for providing an RF detection signal representing said sensory input, an arrangement for identifying each of said remote sensors by means of an individual identifying address comprising:

an address memory in each of said plurality of remote sensors for storing an individual identifying address associated with its respective remote sensor;

keyboard input means for generating an individual identifying address;

first memory means for storing address data;

control means coupled to said memory means and to a remote sensor and said keyboard input means and responsive to an identifying address output from said keyboard input means for storing said identifying address in said first memory means and the address memory of a remote sensor and for subsequently comparing an address received from a remote sensor with said identifying addresses stored in said first memory means thereby uniquely identifying each of said remote sensors;

receiver means coupled to said control means and responsive to an RF detection signal from the remote sensors for providing said detection signal to said control means thereby uniquely identifying said one of the remote sensors; and

a remote keyboard/transmitter responsive to user inputs for providing RF commands to said control means via said receiver means for exercising control over said security system.

2. The arrangement of claim 1 further comprising releasable coupling means for connecting said control means to a remote sensor for storing an identifying address therein and for facilitating subsequent decoupling of said control means and said remote sensor and the remote positioning of said sensor.

3. The arrangement of claim 2 further comprising a serial data link for connecting, in combination with said coupling means, said coupling means to a remote sensor for storing an identifying address thereon.

4. The arrangement of claim 1 further comprising a central station coupled to said control means by means of a data communications line, wherein said central station includes second memory means for storing said identifying addresses therein and, following loss of said identifying addresses from said first memory means, for providing the thus stored identifying addresses to said control means for storage again in said first memory means.

5. The arrangement of claim 1 wherein each of said remote sensors further includes a respective status timer for emitting a periodic RF status signal to said control means indicating normal operation of said remote sensor.

6. The arrangement of claim 1 wherein each of said remote sensors further includes a respective tamper sensor for emitting an alert signal to said control means indicating that its associated remote sensor has been tampered with.

7. The arrangement of claim 1 wherein said RF detection signal includes house address information, remote sensor address information, and sensor status information.
