INSTALLATION INSTRUCTIONS

ROUGH-IN MC111M/DM SYSTEM

The rough-in installation should be made during new construction prior to the application of wall covering material. However, retrofit
instructions are included where applicable.

Tools required: Power drill with 1” auger, #2 Phillips screwdriver, wire stripper/cutter, tape measure and level.

DOs DONT's

☛ USE ONLY M&S SYSTEMS BRAND CABLE as called out in

these instructions. The cable is designed and constructed with electrical
specifications necessary for proper audio performance. Important:

The use of non M&S SYSTEMS brand cable will void the
product warranty! Note: All M&S SYSTEMS cable has M&S SYSTEMS

and the part number printed on it!

☛ USE or MS4XSC cable for room stations, remote controls and

volume controls.

☛ DO NOT EXCEED 200 FEET of cable for any one run or 700 FEET

for the entire system. The maximum number of stations including the
master is 10.

☛ USE or MS4DCXSC for door stations. The maximum number of

door stations is two.

☛ RUN A SINGLE CABLE from the master unit location to each room

station or control (Home Run). DO NOT LOOP CABLE from one
station to another. Looping will cause electronic feedback.

☛ DO NOT STAPLE CABLES! Staples cause shorts.

&

☛ DO NOT SPLICE CABLES. Splices are unreliable and defeat the

signal isolation properties of the cable

☛ KEEP CABLES AT LEAST 18 INCHES FROM

FLUORESCENT 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 in
the intercom.

☛ 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.

☛ Outside cable runs should be underground through PVC conduit (one

cable per conduit unless shielded cable MS4XSC or MS4DCXSC is used).
This cable is not weatherproof, therefore, it must be protected. PVC
must be sealed on each end to prevent condensation in the pipe.

☛ If extra cables are run for possible future speaker additions, care must be

taken that these cables do not get connected to the master unit.
Unterminated cables (no station) connected to the master unit will cause
electronic feedback that will damage the master unit.

DOs DONT's

Careful consideration should be used when determining wall housing
location. DO NOT install wall housing in the following locations

☛ DO NOT Install wall housing in return air ducts.
☛ DO NOT install wall housing in exterior walls
☛ DO NOT Install wall housing underneath cabinets or over counter

tops.

☛ DO NOT install wall housing in stud cavities with other 120/240

appliances.

☛ DO NOT install wall housing within 18” of dimmers, fluorescent

light fixtures, security wiring and other control wiring.

☛ DO NOT install wall housing within 2” of room corners.
☛ DO make sure all mounting rings are level and oriented as

shown in these instructions.

Locate an NMR5 mounting ring for the master unit. Position
the mounting ring approximately 52” high. Have a qualified
electrician run a

1 2 0 VA C / 6 0 H z
receptacle with
ground connection
from the power
panel to a remote
junction box in
which to mount the
RT35 power
transformer. Install
and connect the
remote power
transformer as
shown in Figure

SPEAKERS N14, N35, N15D

At each room station location, nail or
screw the NMR5 mounting ring (for
N14, N35, N15D or NWRC14) to a
vertical wall stud approximately 52”

:

above the floor. RETROFIT: locate
mounting rings at least 1” from studs.

From the master unit location, run
MS4XSC cable to each remote station
location. Secure approximately 12” of
wire at the speaker location to protect
wire from dry wall damage. Secure
cables at the master.
