Patent ID: 8552857

Claim:
An apparatus comprising: a control panel of a security system; a plurality of transceivers of the security system, wherein during start up of the security system, each of the plurality of transceivers listen for wireless transmissions from the control panel and from other transceivers of the plurality of transceivers, wherein at least some of the plurality of transceivers detect wireless transmissions from the control panel and each establishes itself as a hub transceiver through which wireless transmissions from other transceivers that are further away and cannot detect the control panel are relayed to the control panel through the hub transceiver and visa versa, the at least some hub transceivers each synchronously communicate with the control panel of the security system in an assigned slot of a TDMA channel; at least a first of the plurality of transceivers not able to detect the control panel asynchronously transmitting a priority message on a priority channel that is different than the TDMA channel; and at least a second of the plurality of transceivers established as a hub transceiver that detects an information content of the asynchronous priority message on the priority channel and retransmits the detected information content synchronously on the TDMA channel to the control panel.
