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;
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.

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 (

10. An emergency system for providing an emergency function comprising:
-
a plurality of emergency devices, each for providing the emergency function; a controller for dividing the plurality of emergency devices into a plurality of different groups of devices; a transmitter controlled by the controller for transmitting a signal to the devices in only a group of devices to initiate a test operation and so the devices in the group are able to communicate data back to a control receiver relating to the test; and wherein the controller causes only one group at a time to initiate the test operation so that each group can be controlled to perform a test operation at different times. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. An emergency system for providing an emergency function, comprising:
-
at least two controllers; a plurality of emergency devices, each for providing the emergency function; each controller having a transmitter for providing a signal to the emergency devices for initiating a test operation of the devices; at least one of the controllers also being for balancing the system by forming a mesh network and for distributing the emergency devices so that there is a balance between the emergency devices which communicate with one of the controllers and the emergency devices which communicate with the other of the controllers. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
