1. A method of an intelligent light controller controlling a light, comprising:
continuously providing, by a power switch, power to the intelligent light controller from either a normal power supply or an emergency power supply, wherein the power switch switches to the emergency power supply upon detection of failing of the normal power supply; detecting, by the intelligent light controller, a switch from the normal power supply to the emergency power supply by the power switch, comprising determining that the intelligent light controller has been rebooted; powering, as controlled by the intelligent light controller, the light for a predetermined period of time after detecting the switch from the normal power supply to the emergency power supply by the power switch; confirming the switch from the normal power supply to the emergency power supply by the power switch only after determining the intelligent light controller has been rebooted, comprising:
initiating, by the intelligent light controller, communication from the intelligent light controller to a non-emergency device after detecting the switch from the normal power supply to the emergency power supply;confirming the detecting of the switch from the normal power supply to the emergency power supply when the communication initiated from the intelligent light controller to the non-emergency device is not successful; over-riding the powering of the light for the predetermined period of time when the communication initiated from the intelligent light controller to the non-emergency device is successful during the predetermined period of time; executing, by the intelligent light controller, an energy-savings behavior control of the light. |
