Product Overview

The DIM-1 Doorbell Interface Module’s primary purpose is to mute a multi­source/multi-zone audio system so a preexisting doorbell can be heard when it
rings. The DIM-1 does not generate an audible chime, but provides a six-second
12V trigger to the multi-zone system which is used to mute the system so the
doorbell can be heard. The DIM-1 connects the Russound CA4.4i, CA6.4i,
CAV6.6 and the PR-4Zi multi-zone systems to the doorbell of the home by a
few simple connections.

Installation Instructions

DIM-1 installation requires an existing doorchime with door button that
operates on 12-18VAC or DC. It also requires a 12VDC power supply
(Russound 846C, not included).

1) Turn off the power to the doorbell transformer and the audio distribution
system. You will be making open wire connections to the doorbell.

2) The DIM-1 should be located indoors and mounted within 3 feet of the
multi-zone audio system and convenient to the electrical outlet that the
12VDC power supply will use. The DIM-1 should be positioned so that the
LED indicators can be seen during installation.

3) Connect the DIM-1 "TRANS" terminal to the transformer terminal that is
connected directly to the doorbell chime module. Connect the doorbell

switched contacts at the doorbell chime module to the connections
labeled “DB1,” “DB2” and “DB3” on the DIM-1. This connects up to 3
separate doorbell buttons to the DIM-1. Refer to Figure 1. Note that the
connectors can be unplugged for easy wiring.

4) Connection to Multi-zone System: The trigger
output of the DIM-1 connects to the audio
system using a 1/8" mono plug. Connect the
mono plug to the controller (see below for
specific system connections) and snip off the
excess length from the other end of the cable.
Strip the two wires from this end and
determine which wire comes from the tip by
using a continuity meter. The wire from the
tip (+) connects to the "TRIG OUT (+)"
terminal of the DIM-1. The other wire from the
sleeve (-) connects to the "TRIG OUT (-)" of
the DIM-1. Refer to Figure 2.

4a) PR-4Zi Connection: For operation with the PR-4Zi, connect the 1/8” mini

plug into the Mute Input connection. Refer to Figure 3.

4b) CAi Series Connection: For operation with the CA4.4i/CA6.4i, connect the

1/8” mini plug into the Mute Input connection. Refer to Figure 4.

4c) CAV Series Connection: For operation with the CAV6.6, connect the 1/8”

mini plug into the Page Trigger Input connection. Refer to Figure 5.
