RRU - Emergency Power Control

The Remote Relay Unit (RRU) provides 120 or 277 VAC input voltage configurations. The RRU is designed to force all outputs in the lighting control panel to an emergency scene regardless of the control panel programmed output status. This allows the override of outputs to full bright during loss of normal (grid) power to allow an alternate power source to drive the lighting loads. Once the RRU senses the normal power returning, the control panel will return to the normal programmed operating mode.
