A wireless communication system is arranged in a generally linear chain and is initially set up by providing a control module (100) and a first communications module (101). The communications module (101) transmits a radio frequency wireless message to the control module (100), and the control module (100) has address number (0), and the communications module (101) is allocated address number (1), so that it communicates directly with the control module (100). When a second communications module (102) is to be inserted into the system in the position shown in figure (5)(i.e. at the end of the chain remote from the control module (100)), the new module (102) is caused to emit a message in a set-up mode. Initially, the existing module (100, 101) which received the message with the strongest signal intensity (module (101) in the case of figure (5), because of its proximity to the new module (102)) is identified. The new module (102) is then caused to communicate directly with the existing module (101) by allocating address number (2) to the module (102).
