Abstract: In response to determining that the line power source for a subset or all member devices of a lighting control group is interrupted, an emergency luminaire enters an emergency mode (EM) active state by controlling a light source, via a driver circuit, to continuously emit emergency illumination lighting. Upon entering the EM active state, the emergency luminaire transmits, via a wireless lighting control network, an EM active message to a lighting control group repeatedly at a predetermined time interval. Emergency luminaire receives, via the wireless lighting control network, an EM exit message from another member device indicating to exit the EM active state. In response to receiving the EM exit message from the other member device, the emergency luminaire exits the EM active state by controlling the light source, via the driver circuit, to discontinue emitting the emergency illumination lighting.
