Installing the dmc3-4
The dmc3-4 ships configured for a 3-wire retrofit system. If you are
replacing a 4-wire system you must change the jumper setup on the
dmc3-4 master. The jumper change must be completed before any
cables are
connected. To
change the
jumpers just pull
them off the
existing connection (Figure
12) and place them in the
4-wire position show in
Figure 13.
Suspend the master unit
from the wall housing by
looping the third
hand wire (thick
green wire) over the hook at the top of the housing. Be careful not to
damage the wall surface.
If the dmc3-4 system has more than 9
room stations, some room selector
switches will control two room stations.
Connect each Green wire (except patio
Green) to a single green terminal on
the master. Each numbered Green
terminal corresponds to a remote
station selector switch. Note: No more
than 3 Green wires can be connected to
any Green terminal and not to exceed
15 speakers for the 4-wire or 13
speakers for the 3-wire system. This
limitation does include remote controls
and volume controls but not door stations. The station location can be
