Mounting
UIO-256 Frames are generally mounted in the front of
an equipment rack near a Master Controller Breakout
Panel for ADAM intercom systems or near the matrix
frame for ADAM CS intercom systems. When position-
ing a UIO-256, consideration should be given to the
visibility of the front panel status indicators and access
to the reset switch. Also, consider access to the rear
panel for fuse replacement or changes to the DIP switch
settings, etc. There are no ventilation requirements.
