发明名称 A low current RF alarm device mesh network
摘要 <p>A wireless alarm device network (1) comprises alarm devices (A-J, L) each having a processor, a wireless communication interface, and a condition sensor. The devices are communicate by wirelessly transmitting messages, and in a learning mode, automatically register in a monitoring cluster according to received signal strengths. A device (A-J, K) recognises a device as being in its cluster if at least received signal strength exceeds a threshold. Each device is adapted to monitor each other device or devices in its cluster, and to generate an alert if it determines that a device in its cluster is not sending messages.</p>
