Access Interface
Prepare for installation
The EchoAccess Interface ships with the electronics, wall plate, and wire
termination kits including wire pigtails for 24 VDC auxiliary power and
EchoConnect.
The station may be installed into an industry-standard flush-mount back box
(RACO 690 or equivalent provided by others) or surface-mount back box (sold
separately and available from ETC).
Installation
The back box must be installed plumb and square for best results. Ensure the
back box is clean and free of obstructions and that all wiring is installed
correctly.
Locate the wire termination supplies included with the packaging.
