Russound DOORBELL INTERFACE MODULE DIM-1 - Manual (Page 2)

Product Overview
The DIM-1 Doorbell Interface Module’s primary purpose is to mute a multi-
source/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
