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.
