An emergency lighting network
Abstract
An emergency lighting network (1) has a central controller (2) which is connected to 10 spurs 8, each of which can have up to 100 nodes. Each node is associated with a particular luminaire. Each node protects battery and lamp status using a light sensing resistor. Drive circuit status is detected by monitoring voltage across a status LED. The nodes process data locally and transmit only diagnostic data back to the central controller. This diagnostic data indicates what part of the luminaire is faulty.
