Russound DIM-1 instruction manual 4Connection to Multi-zoneSystem: The trigger, PR-4Zi, CAi Series

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	POWER	DOORBELL INTERFACE
system using a 1/8" mono plug. Connect the			DB3 DB2 DB1 TRANS
mono plug to the controller (see below for	+12V DC	OUT
specific system connections) and snip off the	TRIG	TRIG
excess length from the other end of the cable.
Strip the two wires from this end and			Figure 2
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			(+) Tip
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.
