Abstract

A security system comprises a system control panel for arming and disarming the security system. A door sensing unit comprises a first transceiver interconnected with the system control panel over a network. The first transceiver is mounted proximate to a door that defines at least a portion of a perimeter around an area to be monitored by the security system. The first transceiver has an detection field proximate to the door. A disarm device comprises a second transceiver that automatically transmits a disarm device packet. The first transceiver receives the disarm device packet when the second transceiver is within the detection field. The first transceiver sends a disarm message to the system control panel over the network to disarm the security system based on at least the disarm device packet.

Claims

1. A security system, comprising:

a system control panel for arming and disarming the security system;

a door sensing unit comprising a first transceiver interconnected with the system control panel over a network, the first transceiver being mounted proximate to a door that defines at least a portion of a perimeter around an area to be monitored by the security system, the first transceiver having a detection field proximate to the door; and

a portable device comprising a second transceiver, the second transceiver automatically transmitting a device packet, the first transceiver receiving the device packet when the second transceiver is within the detection field, the first transceiver sending a disarm message to the system control panel over the network to disarm the security system based on at least the device packet.

2. The system of claim 1, the door sensing unit further comprising a motion sensor mounted proximate to the door for detecting motion proximate to the door within the area to be monitored, the disarm message being based on at least the motion detected by the motion sensor.

3. The system of claim 1, the door sensing unit further comprising:

a memory for storing a first System identifier (ID) associated with the security system and at least one Device identifier (ID) associated with at least one approved portable device; and

a processor for processing the device packet, the device packet further comprising a second System ID and a second Device ID, the second Device ID being associated with the portable device, the processor comparing the first System ID and the at least one Device ID to the second System ID and the second Device ID, respectively, the first transceiver sending the disarm message when the System IDs and the Device IDs are the same.

4. The system of claim 1, wherein the device packet further comprises at least one of a System ID or a Device ID, the System ID being associated with a security system that the portable device is approved to communicate with and the Device ID being associated with the portable device.

5. The system of claim 1, wherein the second transceiver transmits a plurality of the device packets at predetermined intervals over time.

6. The system of claim 1, wherein the portable device further comprising at least one button for manually generating a device packet to be sent to the first transceiver, the device packet requesting at least one of a mode change in the security system a status of the security system.

7. The system of claim 1, the door sensing unit further comprising:

a door contact mounted proximate to the door for identifying open and closed positions of the door; and

a motion sensor mounted proximate to the door for detecting motion proximate to the door within the area to be monitored, the first transceiver sending the disarm message when the door contact identifies the open position and the motion sensor detects motion.

8. The system of claim 1, wherein at least one of the door sensing unit or the system control panel comprises:

a memory for storing at least a first ID associated with at least one of the security system or at least one approved portable device; and

a processor for processing the device packet, the device packet further comprising at least a second ID, the processor comparing the first ID to the second ID, at least one of the first RF transceiver or the system control panel prohibiting the disarm message when the first ID and the second ID are different.

9. A method for automatically disarming a security system, comprising:

periodically transmitting a packet with a portable device, the packet comprising at least one identifier (ID) associated with at least one of the portable device or the security system;

receiving the packet with a transceiver interconnected with the security system;

comparing the at least one ID to at least one value associated with approved portable devices and the security system; and

disarming the security system when the at least one ID corresponds to the at least one value.

10. The method of claim 9, wherein the at least one ID further comprises at least one of a system ID associated with the security system or a device ID associated with the portable device.

11. The method of claim 9, wherein the security system comprises a perimeter with at least one door, the perimeter having a monitored area there-within, the method further comprising:

sensing motion within the monitored area proximate to the at least one door;

detecting that the at least one door is open; and

preventing an alarm from being generated based on at least the motion.

12. The method of claim 9, wherein the security system comprises a perimeter having a monitored area there-within, the perimeter being at least partially defined by a door having an associated sensor, the method further comprising:

detecting an open status of the door; and

disarming the security system when a valid packet is received by the associated sensor.

13. The method of claim 9, further comprising mounting the transceiver proximate to a door, the transceiver having a detection field in which the transceiver may receive the packet.

14. The method of claim 9, further comprising:

receiving an input from a user to arm the security system; and

discarding the packet sent by the portable device for a predetermined period of time.

15. The method of claim 9, wherein the security system comprises a perimeter with at least one door, the perimeter having a monitored area there-within, the method further comprising:

sensing motion within the monitored area proximate to the at least one door;

detecting an open status and a closed status of the at least one door; and

re-arming the security system when the open status is detected for less than a predetermined amount of time.

16. The method of claim 9, wherein comparing the at least one ID to the at least one value comprises comparing the at least one ID to the at least one value using at least one of a system control panel of the security system or a door sensing unit that is proximate a door that defines at least a portion of a perimeter around an area to be monitored by the security system.

17. The method of claim 9, further comprising storing the at least one value associated with approved portable devices and the security system using at least one of a system control panel of the security system or a door sensing unit that is proximate a door that defines at least a portion of a perimeter around an area to be monitored by the security system.
