Installation (Continued)
Optional Expansion Hub Installation
To increase the system’s capacity,
a second hub can be connected to
the primary hub. The hubs connect
to each other with up to 150 feet of
Cat-5 cable. Each hub requires its
own power supply.
Mount the second hub in the
enclosure (or in another enclosure).
Connect the primary hub to the
second hub using the connectors
labeled EXPANSION. Note: Match
the wire colors to the connector
on the 1st hub, fl ip the wire pair
order on the second hub (see
Figure 11).
Connect up to eight additional
stations to the expansion hub.
Wiring is the same as the primary
hub.
Optional Audio Input Wall Plate
An external audio source can be
connected to the system using the
Model DMC-10AWP wall plate. The
wall plate connects to one of the
hub’s station connectors in place of
a station. Room and patio stations
set to Listen Mode can play the
audio source. The audio source will
be automatically muted when the
intercom is in use.
The audio input wall plate also
features an input level control and
a mute output. The mute output
is a relay contact closure that can
be used to silence an independent
music system when the intercom is
in use.
