Introduction
Linear’s M&S Systems brand Model DMC-10 Structured Wiring Intercom
System offers several advanced features never before available in an
intercom system. Its distributed hub design provides easy installation and
structured wiring mounting compatibility necessary for modern residential
and light commercial applications.
The room, door, and patio stations showcase a new, contemporary design,
crafted to blend smoothly into the installation’s decor. Station faceplates
are available in a variety of colors to further customize each installation.
Room station keypads are illuminated with soft blue indicators while the
intercom is in use. The door and patio station keys are illuminated with
white lighting for easy nighttime operation.
The heart of the system is the Model DMC-10H Intercom Hub. The intercom
hub grid mounts in a structured wiring enclosure. Up to eight room, door,
and patio stations in any combination can be connected to the system hub
using up to 500 feet of standard Cat-5 cable for each station. For larger
installations, a second system hub can be added for expansion, providing a
total system capacity of up to 16 stations. The Model DMC-10AWP Audio
Input Wall Plate can be added to the system to connect an external audio
source for distribution throughout the intercom system.
The room, patio, and door stations mount inside standard 2-gang junction
boxes and are easy to install and wire. Each station and the system hub
contains color-coded Type 110 punch-down terminal blocks for fast and
reliable connection to Cat-5 cable. A 12-volt switching power supply is
included with each intercom hub.

Safety Information and Cautions
Explanation of Graphic Warning Symbols
This symbol is intended to alert the user to the presence of un-insulated
“dangerous voltage” within the product’s enclosure that may be of
sufficient magnitude to constitute a risk of electric shock.
This symbol is intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the literature
accompanying the device.
WARNING! To prevent fire or shock hazard, do not expose this device
to rain, water, or wet locations.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK
DO NOT REMOVE COVER (OR BACK)
NO USER-SERVICEABLE PARTS INSIDE
REFER SERVICE TO QUALIFIED PERSONNEL
General Wiring Cautions
• DO NOT USE EXCESSIVE FORCE ON PUNCH-DOWN TERMINALS! IF
USING AN IMPACT TYPE 110 PUNCH-DOWN TOOL, SET THE FORCE
ADJUSTMENT TO “LOW” BEFORE TERMINATING CAT-5 CABLES.
• The 120 VAC line to the structured wiring enclosure’s junction
box must be run by a licensed electrician.
• Individual CAT-5 cable runs from the hub to any station or
audio input wall plate should not exceed 500 feet.
• Label all cables for identification at the intercom hub.
• DO NOT SPLICE CABLES! Splices are unreliable and defeat
the signal isolation properties of the cable.
• DO NOT STAPLE CABLES! Staples cause shorts.
• DO NOT RUN 120 VAC ELECTRICAL WIRES INSIDE INTERCOM STATION JUNCTION
BOXES. If you encounter 120 VAC wires running through station junction boxes,
you must have a qualified electrician rerun those wires around the junction box.
• KEEP CABLES AT LEAST 18 INCHES FROM FLORESCENT LIGHT FIXTURES, DIMMER
CONTROLS, AND ALL OTHER WIRING. This includes AC wiring, security cable, cordless
phone units, and other control wires. These can cause a “hum” or “buzzing” sound.
• Keep all cables away from objects such as heating and air conditioning ducts, metal
construction plates, and anything else with sharp edges that can damage cables.
Intercom Room Station Cautions
• DO NOT install room stations in saunas. They will not withstand the extreme heat or moisture.
• DO NOT install room stations within 10 feet of other room stations, in the same stud
cavity as other room stations, or facing each other. This will cause acoustic feedback.

Safety Information and Cautions (Continued)
Important Safety Notes
POWER SOURCE This unit should only be connected to a
110-120 VAC power source as marked on the unit.
GROUNDING OR POLARIZATION Do not defeat the safety purpose of the polarized
or grounding-type plug. A polarized plug has two blades with one wider than the
other. A grounding type plug has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety. If the provided plug does not fit
into your outlet, consult an electrician for replacement of the obsolete outlet.
NON-USE PERIODS Always turn the unit off and unplug when it is
not being used or left unattended for long periods of time.
OBJECT AND LIQUID ENTRY Never push objects of any kind into the unit through
the cabinet slots as they may touch dangerous voltage points or short out parts that
could result in a fire or electric shock. Never spill liquid of any kind on the unit.
CLEANING Unplug the unit from the wall outlet before cleaning or polishing
it. Do not use liquid cleaners, aerosol cleaners, gasoline or other flammable
fluid. Clean the exterior of the unit with a slightly damp cloth.
WATER AND MOISTURE Do not use power line operated units near water - for example, near a
bathtub, washbowl, kitchen sink, or laundry tub, in a wet basement, or near a swimming pool.
VENTILATION The appliance should be situated so that its location or position does not interfere
with its proper ventilation. For example, the unit should not be situated on a bed, sofa, rug or
placed in a built-in installation that may block the flow of air through the ventilation openings.
POWER CORD PROTECTION Power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against them paying particular attention to

Installation
System Design
Evaluate the installation to determine locations for mounting the
intercom components. The intercom hub mounts in a new or existing
structured wiring enclosure. The DMC-10RS room stations can be
located in any rooms that require communications. DMC-10PS patio
stations are weather resistant and designed to be mounted in protected
areas outdoors. DMC-10DS door stations are also weather resistant and
typically mounted next to the primary visitor entrance and any other
auxiliary entrances. Up to eight stations of any type can be connected
to one DMC-10H hub. An additional DMC-10H hub can be connected to
the primary hub for expansion, increasing the system capacity to sixteen
stations total.
