Abstract:
1. A method of inserting a communications module into a wireless communication system comprising at least one control module and a plurality of first communication modules, wherein the system is adapted to transmit messages either directly or indirectly between modules, and wherein each said first communications module is adapted to receive a wireless message and transmit said message to a further first communications module or to a said control module, and is programmed with respective addresses identifying modules with which it communicates messages directly when in a communication mode, the method comprising: (i) causing a second communications module, which is to be inserted into the system, to transmit a first signal in a set-up mode; and (ii) if said first signal is directed by at least two said modules capable of communicating directly with each other, causing said second communication module, by means of a second signal from at least one said control module updating the address of one of said modules which detected said first signal, to be installed to communicate directly, when in said communication mode, with two said modules which detected said first signal, including the module whose address was updated by said second signal.
