Claim of US Patent No. 11,032,894

1. A method of controlling a lighting control system comprising:detecting, via a detector circuit connected to a lighting control module, an AC line voltage of an electrical line connected to a power terminal of the lighting control module, the lighting control module configured to cause a transmission of a quantity of electrical energy to a lighting circuit of a light fixture electrically connected to the power terminal;
detecting whether a change in the AC line voltage exceeds a threshold over a pre-specified period of time; and
in response to detecting that the change in the AC line voltage does not exceed the threshold over the pre-specified period of time, reducing a flow of electricity transmitted to the lighting circuit to turn off the light fixture and displaying an icon on a tactile display coupled to the lighting control module.
