Abstract:
A remote control system for remotely controlling a plurality of alternating current electrical appliances, comprising;a plurality of wireless receivers connectable to the alternating current electrical appliances; and a wireless remote control transmitter, located remote from the wireless receivers, for generating and transmitting coded infrared frequency to the wireless receivers to control the alternating current electrical appliances; wherein the wireless remote control transmitter comprises: means for generating and transmitting light intensity control infrared instructions to the wireless receivers for controlling light intensity of connected lighting; means for generating 24-hour timer information to the wireless receivers to control daily activation and daily deactivation of the alternating current electrical appliances; means for providing a selectable set of sleep timer information to the wireless receivers to activate the alternating current electrical appliances within a specified duration; means for generating energy saving interval timer information to the wireless receivers, for the wireless receivers to repeatedly control an activation time and a deactivation time of the alternating current electrical appliances; means for learning and memorizing infrared frequency instructions from other wireless remote control transmitters for unifying as many wireless remote control transmitters as permitted into one master remote controller; a light sensor for determining activation of keypad back lighting during a key press when an ambient light level is low, for enabling a user to see the wireless remote control transmitter in darkness; and wherein of the wireless receivers comprises: means for activating a self-bypass upon detecting a predetermined sequence from a main switch connected to the wireless receiver; upon detecting the predetermined sequence from the main switch connected to the wireless receiver, in tandem within five seconds besides bypassing the wireless receiver, means for capturing an infrared frequency code corresponding to a key from another infrared remote and forwarding the infrared frequency code to a microprocessor for learning and memorizing of the infrared frequency code and directly transferring control of the alternating current electrical appliance to that key of the other infrared remote; and a dual safety mechanism comprising a mechanical safety bypass switch and a fuse provided as a safety measure in case the wireless receiver malfunctions.
