A method and a device for supervising a home wireless system wherein the home wireless system comprises a plurality of peripheral wireless nodes (14; 16; 19; 21; 23), a first gateway (12) having wireless communication means for communicating with and controlling associated peripheral wireless nodes.

A method and a device for supervising a home wireless system wherein the home wireless system comprises a plurality of peripheral wireless nodes (14; 16; 19; 21; 23), a first gateway (12) having wireless communication means for communicating with and controlling associated peripheral wireless nodes. Other steps are installing at least one second gateway (12′; 32), each of said peripheral wireless nodes (14; 16; 19; 21; 23) being assigned to one of said first gateway (12) and said at least one second gateway (12′; 32), maintaining a supervision timer for each assigned peripheral wireless node (14; 16; 19; 21; 23), transmitting from each of said peripheral wireless nodes (14; 16; 19; 21; 23) a periodic status message, resetting in the gateway said supervision timer when receiving a periodic status message from an assigned peripheral wireless node (14; 16; 19; 21; 23), and reporting from a first gateway to said at least one second gateway an assigned peripheral wireless node (14; 16; 19; 21; 23) as failed when no periodic status message has been received within a predefined time period. The device also comprises at least on remote central monitoring station (22) and timing means in said gateways and said nodes.

1. A method for supervising a wireless home alarm system, wherein the wireless home alarm system comprises a plurality of peripheral wireless alarm detectors, the peripheral wireless alarm detectors comprising at least a first infrared detector and at least a first perimeter alarm detector, a first gateway having a first wireless communication means for communicating with and controlling associated peripheral wireless alarm detectors, and a second communication means for communicating with a remote central monitoring system, the method comprising: a. installing at least one second gateway in the wireless home alarm system, each of the peripheral wireless alarm detectors being assigned to and controlled by one of the first gateway and the at least one second gateway;b. communicating all messages created in each peripheral wireless alarm detector through and acknowledging such messages in the associated gateway controlling the peripheral wireless alarm detector only;c. maintaining in each gateway a supervision timer for each assigned peripheral wireless alarm detector;d. transmitting from each of the peripheral wireless alarm detectors a periodic status message;e. resetting in each gateway said supervision timer when receiving the periodic status message from an assigned peripheral wireless alarm detector;f. reporting from the first gateway to the at least one second gateway an assigned peripheral wireless alarm detector as failed when no periodic status message has been received within a predefined time period;g. reporting from the first gateway and from said at least one second gateway to the remote central monitoring system a peripheral wireless alarm detector as owned when an assignment process is completed;h. reporting form the first gateway to the remote central monitoring system the peripheral wireless alarm detector as failed when no periodic status message has been received within the predefined time period; andi. storing in the remote central monitoring system information indicating the peripheral wireless alarm detector as failed. 2. The method as claimed in claim 1, further comprising: a. maintaining in said first gateway a supervision timer for said at least one second gateway,b. transmitting from said at least one second gateway a periodic status message,c. resetting in said first gateway said supervision timer when receiving a periodic status message from said at least one second gateway,d. reporting from the first gateway to the remoted central monitoring system said at least one second gateway as failed when no periodic status message has been received within a predefined time period, ande. storing in said remote central monitoring system information indicating the at least one second gateway as failed. 3. A wireless home alarm system comprising: a plurality of peripheral wireless alarm detectors, the peripheral wireless alarm detectors comprising at least a first infrared detector and at least a first perimeter alarm detector;a first gateway having a first wireless communication means for communicating with and controlling associated peripheral wireless alarm detectors, and a second communication means for communicating with a remote central monitoring system;at least one second gateway, each of the peripheral wireless alarm detectors being assigned to and controlled by one of the first gateway and the at least one second gateway, each gateway maintaining a supervision timer for each assigned peripheral wireless alarm detector, wherein the system performs the following steps: a. communicating all messages created in each peripheral wireless alarm detector through and acknowledging such messages in the associated gateway controlling the peripheral wireless alarm detector only;b. transmitting from each of the peripheral wireless alarm detectors a periodic status message;c. resetting in each gateway said supervision timer when receiving the periodic status message from an assigned peripheral wireless alarm detector;d. reporting from the first gateway to the at least one second gateway an assigned peripheral wireless alarm detector as failed when no periodic status message has been received within a predefined time period;e. reporting from the first gateway and from said at least one second gateway to the remote central monitoring system a peripheral wireless alarm detector as owned when an assignment process is completed;f. reporting form the first gateway to the remote central monitoring system the peripheral wireless alarm detector as failed when no periodic status message has been received within the predefined time period; andg. storing in the remote central monitoring system information indicating the peripheral wireless alarm detector as failed. 4. The system as claimed in claim 3, wherein the system further performs the following steps: a. maintaining in said first gateway a supervision timer for said at least one second gateway,b. transmitting from said at least one second gateway a periodic status message,c. resetting in said first gateway said supervision timer when receiving a periodic status message from said at least one second gateway,d. reporting from the first gateway to the remoted central monitoring system said at least one second gateway as failed when no periodic status message has been received within a predefined time period, ande. storing in said remote central monitoring system information indicating the at least one second gateway as failed.
