Important: Verify all cable run locations prior to connecting if they 
were not labeled at rough-in. Incorrectly connecting cables to the 
master, room stations or door stations may result in system damage. 
Install the optional chime module MC3 or 
MC8 in the wall housing by pressing the 
chime module over the 4 plastic 
standoffs attached to the wall housing as 
shown in figure 8. Refer to the 
instructions shipped with the chime 
module. 
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. Be 
careful not to damage the wall surface. See figure 9. 
If the dmc1 system has more than 9 
room stations, some room selector 
switches will control two room stations. 
Do not exceed more than 15 total 
speakers on the system. This limitation 
does not include remote controls, 
volume controls, speakers connected 
to the optional stereo power amp, of 
door stations. The station location can 
be noted on the inside of the front 
access panel on the left side of the 
dmc1 master. 
Connect the red and black wires of 
the door station cables 
(MS4DCX/MS4DCXSC) to the red and black door speaker terminals on 
the dmc1 master as shown in figure 10. Insulate the bare wires using 
some of the jacket material to prevent shorting to the circuit board. 
Connect this wire to terminal labeled shield. Connect all orange wires 
from the door stations to the common terminal on the MC3 or MC8.
