Wireless lighting control system with automatic emergency mode exit network protocol

A lighting control system comprising:

• a lighting control group including a plurality of member devices, the member devices including a group monitor, an emergency luminaire, and a non-emergency mode (EM) device, wherein the emergency luminaire includes:
• an emergency luminaire wireless radio communication interface system including at least one transceiver configured for wireless communication via a wireless lighting control network over a wireless lighting control network communication band for lighting control and systems operations;
• an emergency luminaire light source to continuously emit emergency illumination lighting during an emergency;
• an emergency luminaire driver circuit coupled to the emergency luminaire light source to control light source operation of the emergency luminaire light source;
• an emergency luminaire power supply driven by a non-line power source;
• an emergency luminaire processor coupled to the emergency luminaire wireless radio communication interface system and the emergency luminaire driver circuit;
• an emergency luminaire memory accessible to the emergency luminaire processor;
• and
• emergency luminaire programming in the emergency luminaire memory, wherein execution of the emergency luminaire programming by the emergency luminaire processor configures the emergency luminaire to implement functions, including functions to:
• determine that a line power source for powering on a subset or all of the member devices is interrupted such that line power is no longer available via the line power source;
• in response to determining that the line power source for the subset or all of the member devices is interrupted, enter an emergency mode (EM) active state by controlling the emergency luminaire light source, via the emergency luminaire driver circuit, to continuously emit the emergency illumination lighting;
• upon entering the EM active state, transmit, via the wireless lighting control network, an EM active message to the lighting control group repeatedly at a predetermined time interval;
• receive, via the wireless lighting control network, an EM exit message from another member device indicating to exit the EM active state;
• and
• in response to receiving the EM exit message from the other member device, exit the EM active state by controlling the emergency luminaire light source, via the emergency luminaire driver circuit, to discontinue emitting the emergency illumination lighting.
