• Echo-Echoflex Interface does not work without EchoConnect

    The Unison Echo®-Echoflex interface (EEI) integrates Echo systems and Echoflex products together into one system. The EEI requires both Auxiliary power as well as EchoConnect wiring to integrate these products together.

    The Echoflex products communicate with each other and to the Echo system through the EEI. Therefore, if the EEI loses EchoConnect wiring, the Echoflex products will no longer be able to communicate with each other.

    If you have any questions about the Echo-Echoflex Interface, please contact ETC Technical Services.
