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 d e d i c a t e d 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 1 and Figure 2. Use Figure 1 and Figure 3 for plug-in version using RT11.

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.

PATIO SPEAKERS NW14/NW35

Run a single cable MS4XSC from the master unit location to each outdoor speaker location and secure the cable to the correct plastic or metal enclosure by wrapping the cable around a small piece of wood. Use NME5 enclosure for recessed NW14 or
