Abstract

An alarm device (50) has a sensor (52), a digital data processor (54), a wireless RF communication interface (57, 58), and a user interface (53, 54). It communicates in a protocol by wirelessly transmitting messages with other devices within RF range, and which devices are also arranged to communicate according to the protocol. It stores a distribution list of all house coded devices in a network in a sequential order, and processes received acknowledge messages from other devices if they are received in pre-determined time slots determined by said sequential order. The processor includes in an acknowledge message a neighbour list of identifiers of direct communication neighbours, and the processor is configured to maintain a distribution list of identifiers of acknowledging devices included in received neighbour lists, and to determine if a repeat message is required if a neighbour list includes a device identifier not in the current distribution list.
