The RD-122 multi-protocol dimmer features softpatch, remote activated internal scene and advanced chase functions that enable it to provide stand alone operation. Softpatching allows any dimmer channel to be assigned to any incoming control channel. An internal scene provides the ability to activate general lighting from each entrance way with remote switches. The slow chase feature allows gradual lighting changes for visual architectural variety. Each dimmer channel may be individually selected for dimmer or relay mode. High quality semiconductors, over voltage, over current, and over temperature protection provide the reliability and confidence you expect.
