There is usually a reserve switching device or scheme which is activated when the power coming from the main grid disappears. When such an outage happens, the scheme will sense it and disconnect the circuitry from the main source of power (grid) and start up the emergency generators. When the main power is restored, the system will connect you back to it and turn off the emergency generator.
