ABSTRACT:
A system for remote control of electrical load devices, particularly electrical lighting where the commands are broadcast over a radio pager system. A radio pager receiver is located within or nearby the electrical light fixture and is normally in a standby state, receives the commands broadcast. The radio pager receiver is connected to a computer processor and electronic circuitry. The computer processor interprets the commands and instructs the electronic circuitry to perform a desired operation. These operations include but are not limited to turning an electrical light element or group of electrical light elements on or off, dimming the light element or reprogramming the electrical light element to be included in a different control group of lights. In addition, before the operation is accomplished, the computer processor checks for the appropriate security code entry. In addition, there are protection mechanisms built into the computer processor so that if the decoding of the commands indicates that a large block of devices is to be turned on at the same time, the operation will be staggered so as to prevent a huge inrush of current and potential for tripping of the building's main electrical overcurrent device or circuit.
