INSTALLING THE CHIME MODULE

Install the optional chime module MC3 or MC8 in the wall

housing by pressing the chime module over the four plastic

standoffs attached to the wall housing as shown in Figure 12.

The DMC3-4 supports the 3-note Model MC3 and 8-note

Model MC8 chime modules. The chime module installs

inside the wall housing and is activated by the Door Station

pushbutton.

1. Install the chime module circuit board by snapping it onto the four

plastic mounting standoffs in the wall housing.

2. Refer to the instructions shipped with the chime module.

OPTIONAL DOOR RELEASE RELAY

The DMC3-4 Master Station contains a dry contact relay that

can be used to control external devices. Typical applications

include activating a door strike, triggering a panic alarm

system, or controlling a home automation or lighting system.

The door release relay has normally open contacts that

are rated at 2 Amps @ 24 Volts AC/DC. The relay can be

activated from the DMC3-4 Master Station or remote scan

Room Stations (Model DMC3RS or DMC4RS) by pressing

the volume up and volume down buttons together for four

seconds. The relay will deactivate when the buttons are

released.

Refer to the following steps for connecting a Model DRW

Door Release Mechanism (see Figure 13). For controlling

other devices, refer to the hook-up instructions supplied

with the device.

1. Route 2-conductor 18 AWG cable from the DMC3-4 Master Station’s

wall housing to the door release location.

2. Route 2-conductor 18 AWG cable from the DMC3-4 Master Station’s

wall housing to a location for a Model RT11 Remote Transformer. The

transformer plugs into a standard 120 VAC outlet.

3. Route the two cables into the Master Station’s wall housing through

the top left wiring access hole or slot. Leave about 12” of extra cable

extending at the wall housing.

4. Zip-tie the two cables together and LABEL THE CABLES “Door

Release”.

5. Use a wire nut to connect one wire from the transformer cable to one

wire from the door strike.
