Abstract

The present invention relates to a remote control unit for cooperating with a security system for convenient arming and disarming thereof and/or status thereof. A low cost of remote preferably cooperates with other components of the system to provide feedback to the user as to the state of the system. The remote control can also be used in a simple, non-threatening method of inputting a security code into a receiving device which is manually or otherwise activated.

Claims

1. A security system comprising a number of sensors for sensing an alarm condition, a control panel for receiving signals from said sensors and processing the same for determination of an alarm event, an interior keypad for inputting information to said control panel, said security system further comprising a wireless remote control arrangement having a portable unit to be carried by a user and an interior receiver arrangement for receiving signals from said portable unit and communicating with said control panel to alter the status of the security system including arming and disarming of the security system;

said portable unit including at least one key actuator and means to generate and transmit a predetermined IR signal in response to actuation of said at least one key actuator, said receiver arrangement upon receipt of said predetermined IR signal from said portable unit providing visual feedback to the user to assist the user in the entry of an identification code produced by means of a series of IR signals produced by multiple actuation of said at least one key actuator and to also assist the user in the entry of instructions to alter the status of the security system, said interior receiver upon receipt of said IR signals to alter the status of the security system instructing said control panel to change the status of the security system in accordance with said received IR signals.

2. A security system as claimed in claim 1 wherein said receiver arrangement and said control panel communicate using a wireless RF communication channel.

3. A security system as claimed in claim 1 wherein said receiver arrangement and said control panel communicate using AC power lines.

4. A security system as claimed in claim 1 wherein said security system includes a plurality of portable units where each unit has its own identifying signal, and said control panel includes means for recognizing each portable unit only during specified time intervals which time intervals are provided to said control panel.

5. A security system as claimed in claim 1 wherein said receiver arrangement includes its own visual display screen which is activated when said predetermined signal of said portable unit is received.

6. A security system as claimed in claim 4 wherein said IR signals of said portable units are highly directional, low power IR signals.

7. A security system as claimed in claim 1 wherein said receiver arrangement and said control panel communicate using a wireless RF communication channel.

8. A security system as claimed in claim 6 wherein said receiver arrangement is powered by AC.

9. A method of arming and disarming a security system wherein the security system has a number of sensors for sensing an alarm condition, a control panel for receiving signals from said sensors and processing the signals for determination of an alarm event, an interior keypad for inputting information to said control panel and a wireless remote control arrangement having a portable unit to be carried by a user and an interior receiver arrangement for receiving directional signals from said portable unit and communicating with said control panel to alter the status of the security system in accordance with signals received from said portable unit, said method comprising

generating and transmitting a predetermined IR signal in response to actuation of at least one key actuator of said portable unit,

receiving and recognizing said predetermined IR signal at said receiver arrangement and providing visual feedback confirming receipt and recognition of said predetermined IR signal by said receiver arrangement,

generating and transmitting further predetermined IR signals in response to multiple actuation of the at least one key actuator of said portable unit to thereby enter an authorization code,

receiving and recognizing said further predetermined IR signals at said receiver arrangement and providing visual feedback confirming receipt and recognition of said predetermined IR signals by said receiver arrangement when the authorization code has been received, and thereafter,

providing visual prompts to alter the status of the security system,

generating additional IR signals by actuating said at least one key actuator of said portable unit in response to said prompts to cause the status of the security system to change,

receiving said additional IR signals at said receiver arrangement and instructing said control panel to change the status of said security system in accordance with said additional RF signals;

and

said control panel effecting the change in status of said security system to arm or disarm the system.
