Abstract
An emergency lighting unit includes a lamp, a backup battery, controller, and a network interface. The controller connects the backup battery to the lamp upon detection of an emergency condition and loss of main power. The network interface interfaces with and receives commands from a fire alarm control panel via a fire alarm network. Each emergency lighting unit may have a unique identifier with respect to the fire alarm network.
