IMPORTANT DO’S & DON’TS

✔DO ensure that all instructions have been followed before power is applied to system. The installation shall be carried out in accordance with all applicable installation rules.

✔DO use only M&S systems brand cable (except for Cat-5 & RG-6) as called out in these instructions. The cable is designed and constructed with electrical specifi cations necessary for proper audio performance.

✔DO use only a dry cloth to clean the exterior plastics on the dmc1 Master Station and Room Stations. DO NOT use liquid or aerosols.

✔DO make gradual bends of the cable where necessary -- no sharper than 1” radius.

✔DO dress the cables neatly with cable ties or Velcro™ wraps. Use loose or moderate pressure.

✔DO use cable-pulling lubricant only for cable runs that may otherwise require great force to install. When cable lubricant is used, read the instructions to be sure it is compatible with the cable jacket material (PVC or FEP).

✔DO avoid stressing cable conductors, limit pulling tension to 25 pounds or less as specifi ed by EIA/TIA-568A standard. Pull cables gradually and with constant tension, taking care not to crush or pinch bundles.

✔DO use grommets to protect the cable where passing through metal studs or anything that can possibly damage them.

✔DO test every installed cable run with a cable tester. “Toning” alone is not acceptable.

✔DO label every termination point. Use a unique identifi er for each cable run. It will make moves, adds, changes, and troubleshooting easier.

✔DO support horizontal cable bundles using board supports, J-hooks, or cable trays.

✔DO have signal cables cross at right angles to power cables to minimize induced interference.

✔DO always obey all local and national fi re and building codes. Be sure to “fi restop” all cables that penetrate a fi rewall. Use plenum-rated cable where mandated.

✔DO follow the grounding and bonding requirements established by Electrical Code TIA standard 607, and equipment manufacturer’s specifi cations.

✔DO NOT locate the dmc1 Master Station or Room Stations in an exterior wall.

✔DO NOT locate the dmc1 Master Station or Room Stations in any wall cavity with any other electrical wiring in the cavity.

✔DO NOT locate Patio Stations in places with direct exposure to sun and weather or in locations that receive direct water spray.

✔DO NOT attach non line-level audio devices or non M&S authorized equipment to the system.

✔DO NOT power up Master Station until all speakers and stations are connected.

✔DO NOT splice or repair cables damaged during wire pulling, install a new cable.

✔DO NOT coil or bundle the cables. This can cause electronic feedback.

✔DO NOT over-tighten the screws for the volume controls, speakers, or the intercom Master Station to prevent cracking.

✔DO NOT install any station or speaker cables inside the 120 VAC transformer enclosure.

✔DO NOT tie cables to electrical conduits or lay cables on electrical fi xtures. Keep cables at least 16” away from fl uorescent lights, HID light fi xtures, or dimmers.

✔DO NOT allow the cable to be sharply bent or kinked at any time.

✔DO NOT install cables “taught” in the ceiling or elsewhere. A good installation should have cables loose, but never sagging.

✔DO NOT run signal cables parallel to power cables without adequate separation to minimize induced interference.

✔DO NOT exert more than 25 pounds of tension on 4-pair cables.

✔DO NOT step on Cat-5 cable during installation.

✔DO NOT overtighten the cable ties, apply cable ties loosely, with random spacing.

✔DO NOT untwist the wire pairs in Cat-5 cable more than 1/2” to avoid crosstalk.

WIRING CAUTIONS

●A licensed electrician must run a 120 VAC line from A DEDICATED 15-AMP BREAKER to the dmc1 (and dmc1CD or dmc1MM, if equipped) transformer.

●Use Cat-5 wire for all dmc1 wire runs excluding Door Station wire runs. For Door Stations, use the M&S Systems brand MS4DCXSC wire that is included with the dmc1H or dmc1HC wall housing kits.

●Individual wire runs should not exceed 350 feet from any single room or Door Station to the dmc1 Master Station or 1000 feet total for the entire system.

●Label all wire runs. Connecting the wires to the dmc1 Master Station, Room Station, or Door Station incorrectly may result in system damage.

●Run a single cable from the Master Station 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 cable.

●KEEP CABLES AT LEAST 18 INCHES FROM FLUORESCENT LIGHT FIXTURES, DIMER 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.

ROOM STATION CAUTIONS

Careful consideration should be used when determining the location of the Room Stations. DO NOT install these devices in the following locations:

✔DO NOT install Room Stations near air return ducts.

✔DO NOT install Room Stations in exterior walls. Insulation materials will change speaker range and effi ciency. 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.

✔DO NOT install Room Stations in stud cavities with other wiring or appliances.

✔DO NOT install Room Stations within 10 feet of other Room Stations or the dmc1 Master Station unit. This will cause acoustical feedback.

✔DO NOT install Room Stations in stud cavities with other Room Stations or the dmc1 Master Station unit. This will cause acoustical feedback.

✔DO NOT install Room Stations facing each other Room Stations or the dmc1 Master Station unit. This will cause acoustical feedback.

Be sure that all Room Station mounting rings are level and oriented as shown in these instructions.

Failure to adhere to these instructions can cause equipment malfunction and void any warranty covered by Linear LLC.
