INSTALLING THE DMC3-4

3-wire or 4-wire Conﬁ guration Jumper Setting

The DMC3-4 ships conﬁ gured for a 3-wire retroﬁ t system.

If you are replacing a 4-wire system you must change

the jumper setup on the DMC3-4 Master Station. The

jumper change must be completed before any cables are

connected. To change the jumpers pull them off the 3-wire

connector pins and place them onto the 4-wire connector

pins (see Figure 14).

Station Connections

During installation, 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 (see Figure 15). Be

careful not to damage the wall surface.

Room Stations and Patio Stations

1. Connect each GREEN wire (except patio GREEN) to a single RM#

green wire terminal on the master. Each numbered RM# green wire

terminal corresponds to a remote station selector switch. Refer to

Figure 16 for wire placement.

✔ NOTE: If the DMC3-4 system has more than 9 room stations, some

room selector switches will control two room stations.

✔ NOTE: No more than three GREEN wires can be connected to any

RM# GREEN wire terminal and not to exceed 15 stations for the

4-wire or 13 stations for the 3-wire system. This limitation does not

include door stations.

2. The station location can be marked on the inside of the door access

panel on the left side of the DMC3-4 Master Station.

3. Connect the GREEN wire(s) from the patio station(s) to the PATIO

green wire terminal.

4. Connect the patio BLACK wire(s) to the patio BLACK terminal.

✔ NOTE: Only two patio stations can be connected to the patio terminals.

5. Combine the room station BLACK wires and connect to the BLACK

terminal.

6. Combine the room and patio station RED wires and connect to the

RED terminal.

7. Combine the room and patio station WHTE wires and connect to the

the WHITE terminal. (4-Wire installations only.)

8. When using shielded wire with drain wires, insulate the bare wires

using some of the jacket material to prevent shorting to the circuit

board. Combine all the drain wires and connect to the SHIELD

terminal.

Door Station Connections

1. Connect the RED and BLACK wires of the door station cables to

the RED and BLACK door station terminals on the DMC3-4 Master

Station (see Figure 16).

2. Connect all ORANGE wires from the door stations to the COMMON

terminal on the MC3 or MC8 chime module.

3. Connect each YELLOW wire to a chime module NOTE selection

terminal. (Do not connect more than one yellow wire per note terminal.)
