The lightning flash with arrowhead
symbol within an equilateral
triangle is intended to alert the
user to the presence of uninsulated
“dangerous voltage” within the
product’s enclosure that may be of
sufficient magnitude to constitute a
risk of shock to persons.
The exclamation point within an
equilateral triangle is intended to
alert the user to the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the product.
• Locate the system away from heat sources such as radiators, heat
registers, stoves, or other heat producing products.
• Do not locate the dmc1 master or room stations in an outside wall.
• Do Not expose the dmc1 to moisture. Doing so can create fire or
shock hazards and impair the warranty.
• Do not place the dmc1 master or room stations in any wall cavity
with any other electrical wiring in the cavity.
• Do not attach devices unauthorized for use with this system.
Authorized devices include:
• Audio components connected via a line level input
• DMC1CD 6-disc player
• Use only M&S Systems certified replacement parts and have them
installed by an M&S Systems dealer or installer. Unauthorized
substitutions can result in fire, electric shock, or other hazards.
• Upon completion of any service or product repair, have the M&S
Systems dealer or installer conduct a safety check to ensure the
system is in proper operating condition.

Cautions: Wiring
• A qualified electrician must run a 120V AC line to the dmc1
transformers.
• USE CAT-5 wire for all DMC1 wire runs excluding the door stations
runs. For the door stations we recommend the use of M&S Systems
Brand MS4DCXSC wire.
• KEEP CAT-5 wiring separate from any 120/240V wiring, dimmers,
security wiring, and other control wiring. Do not allow the CAT-5
wiring to touch any other wiring.
• Individual CAT-5 runs should not exceed more than 350 FEET of
wire from any single room station to the dmc1 master or 1000 total
feet for the entire system.
dmc1
• LABEL all wiring runs. Connecting the wires to the dmc1 master,
room station or door stations incorrectly may result in system
damage.
• Run a single cable from the master unit location to each room
station and door station in a “home run” fashion. Do not loop cable
from one room station to another.
• DO NOT STAPLE CABLES! Staples cause shorts.
• DO NOT SPLICE CABLES. Splices are unreliable and defeat the
signal isolation properties of the cables.
• KEEP CABLES AT LEAST 18 INCHES FROM FLORESCENT LIGHT
FIXTURES, DIMMER CONTROLS, AND ALL OTHER WIRING. This
includes AC wiring, security cable, and other control wires. These
can cause a “hum” or “buzzing” sound.
• KEEP cables away from objects such as heating and air conditioning
ducts, metal construction plates, and anything else with sharp
edges that can damage the cables.

Cautions: Room Station Rough-In
Careful consideration should be used when determining the location of
the room stations, hub box and line level input locations. DO NOT
install these devices in the following locations:
• DO NOT install room stations in return air ducts.
• DO NOT install room stations in exterior walls. Insulation materials
will change speaker range and efficiency. Temperature changes in
the wall will reduce speaker life.
• DO NOT install room stations in saunas. They will not withstand the
extreme heat and moisture.
• DO NOT install room stations underneath cabinets or over counter
tops.
dmc1
• DO NOT install room stations in stud cavities with other wiring or
appliances.
• DO NOT install room stations within 18” of dimmers, fluorescent
light fixtures, security wiring and other control wiring.
• DO NOT install room stations within 10 feet of other room stations
or the dmc1 master unit. This will cause acoustical feedback.
• DO NOT install room stations in stud cavities with other room
stations or the dmc1 master unit. This will cause acoustical
feedback.
• DO NOT install room stations facing other room stations or the
dmc1 master unit. This will cause acoustical feedback.
• DO make sure all mounting rings are level and oriented as shown in
these instructions.

Have a qualified electrician run a dedicated
120VAC/60Hz line with ground connection
from the power panel to the wall housing as
show in figure 3. The dmc1 requires a
dedicated power source to assure no
interference from other equipment caused
by looped power circuits. The ground is
necessary for proper radio reception.
Place transformer enclosure from the inside
of the wall housing into the transformer
enclosure opening at the bottom of the wall
housing as shown in figure 4.
For the
DMC1HC
combo wall
housing have
a qualified
electrician
loop a power

Antennas
Isolate the antenna leads from the intercom cables by running them
through a separate hole in the ceiling plate and in the top of the
wall housing as shown in figure 6. If grouped together the intercom
cables can shield the antenna leads resulting in poor radio
reception. Keep the antenna leads away from metal ductwork and
aluminum backed insulation. These can also shield the antenna
leads.

Run the MS5XSC
cable from the remote amplifier
to each volume control. From
Figure 11 - Power amp wiring
each volume control, run the
MS2SXSC to each respective speaker as shown in figure
11.
The remote power amplifier should be located in a closet
or utility closet and should be located within 6 feet of a
standard NEMA 5-15R 120VAC receptacle. Install a 1gang and a 2-gang box at the location for the remote
amplifier on a stud. Allocate the 1-gang and 2-gang
MS7XSC
boxes relative to one another as shown in figure 12. Run
all MS5XSC cables from the volume controls to the
remote amplifier’s 2-gang box.
Run the MS7XSC cable from the dmc1 to the remote

Door Release Options
The door release option is a dry contact closure provided by the dmc1
master. This dry contact is rated 24V at 4 Amps. The sample applications
below represent some uses of this option. However, only one application
can be used in any dmc1 system at a time.
Door or Gate Release Mechanism
Run a single line of PBVM127X1 from the DMC1H or DMC1HC housing to
the door release mechanism. Connect the red and white wires to the two
wire terminals of the door release mechanism.
Run another single line of PBVM127X1 from the DMC1H or DMC1HC
housing location to a gang box next to a 120VAC receptacle where the
RT11 remote power transformer will be plugged in. Label and secure
cables at the housing.
The door release switch contacts are very versatile and can be used with
many AC/DC door or switch contacts. Be sure to use the wire and power
supply or transformer specified by the door or gate release product being
used.
