Can the Echo Room Controller Provide Just Auxiliary Power


If the internal station power supply on the Echo Room Controller (ERMC) is disabled, does the ERMC still provide auxiliary power?


Yes. The auxiliary output on the ERMC is intended to provide 40mA aux power for the optional ERMC TimeClock. If the ERMC is part of a larger Echo system that uses a separate station power supply, and the ERMC internal power supply is disabled, you can still run and use aux from the main ERMC PCB to its TimeClock or for another Echo device that consumes 40 mA.
