Emergency lighting system
First Claim
1. An emergency system for providing an emergency function, comprising:
- a controller;
a plurality of emergency devices, each for providing the emergency function; and
transmitters and receivers for producing a mesh network for providing wireless communication of data between the controller and the emergency devices so that the operability of the plurality of emergency devices in an emergency situation can be tested by a wireless signal over the mesh network to the emergency devices to initiate a test operation of the devices and for communicating data relating to the test back to a control receiver, each device having a processor for establishing a preferred wireless communication link of the mesh network to another emergency device for relaying the signal and for relaying the data to the control receiver, and for establishing an alternative wireless communication link via a further emergency device, if the preferred wireless communication link is inoperative, the controller balancing the mesh network by forcing at least one of the plurality of emergency devices to detach.

Abstract
An emergency system for providing an emergency function is described in which the system is required to provide an autonomous and self-diagnostic capability so the system can be tested when not in operation in an emergency situation. A plurality of emergency devices 14 are provided which have transmitters and receivers for producing a mesh network (FIG. 1). Each device 14 has a processor 60 for establishing a preferred wireless communication link of the mesh network to another device 14 for relaying signals and messages. The devices 14 are arranged in subnets 50 and the subnets are also grouped into groups of devices 14 which may cross various subnets 50 so that only one group of devices 14 can be tested at a particular time.
