system. 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 damp cloth to clean the exterior plastics on the dmc1 master 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 or room stations in an exterior wall. DO NOT locate the dmc1 master or room stations in any wall cavity with any other electrical wiring in the cavity. DO NOT attach non line-level audio devices or non M&S authorized equipment to the system. DO NOT power up master 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 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. ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ IMPORTANT DO’S & DON’TS A licensed electrician must run a 120 VAC line from A DEDICATED 15-AMP BREAKER to the dmc1 (and dmc1CD, if equipped) transformer. Use Cat-5 wire for all dmc1 wire runs excluding door station and remote power amplifi er 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 or 1000 feet total for the entire system. Label all wire runs. Connecting the wires to the dmc1 master, room station, or door station 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 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. ● ● ● ● ● ● ● ● ● 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 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 each other room stations or the dmc1 master 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. ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ WIRING CAUTIONS ROOM STATION CAUTIONS TABLE OF CONTENTS Tools Required . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 Installation Rough-in kits . . . . . . . . . . . . . . . . . . . . . . . . 1 Wall Housing Installation . . . . . . . . . . . . . . . . . . . . . . . . 2 Transformer Installation . . . . . . . . . . . . . . . . . . . . . . . . . 2 Antenna Rough-in . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 Room Station Rough-in . . . . . . . . . . . . . . . . . . . . . . . . . 3 Patio Station Rough-in . . . . . . . . . . . . . . . . . . . . . . . . . . 4 Door Station Rough-in . . . . . . . . . . . . . . . . . . . . . . . . . . 4 Mono Music Speakers . . . . . . . . . . . . . . . . . . . . . . . . . . 4 External Music Source . . . . . . . . . . . . . . . . . . . . . . . . . 5 Stereo Upgrade . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 Stereo Music Speakers . . . . . . . . . . . . . . . . . . . . . . . . . 5 Door Release Relay . . . . . . . . . . . . . . . . . . . . . . . . . . . 6

The wall housing mounts between two 16” centered studs and holds the master unit, optional CD player, chime module, and power transformer(s). Determine a location for the wall housing. Position the back side of the wall housing fl ush with the back of the 2 x 4 studs with the bottom edge approximately 59” above the fl oor for the dmc1H wall housing or 52” above the fl oor for the dmc1HC wall housing. Be sure the rectangular transformer mounting knockout is on the bottom of the wall housing (see Figure 1). Attach the wall housing to the studs with wood screws. If the studs are spaced farther apart than 16”, use wood shims to make up the difference. ALWAYS SECURE THE WALL HOUSING ON BOTH SIDES. If using the Model dmc1H housing, install the four 1-1/2” snap-in bushings into the knockout holes. TRANSFORMER INSTALLATION The Model TE5D transformer powers the dmc1 master. The Model TE2D transformer powers the optional dmc1CD CD player. Both transformers are supplied in a small metal enclosures that mount to the bottom of the wall housing. Run a 14 AWG 120 VAC power cable (including ground) from a dedicated 15-amp circuit breaker to the wall housing location. The dmc1 requires a dedicated power source to assure there’s no interference from other equipment. The ground is required for good radio reception. Slide the transformer enclosure(s) down into the rectangular transformer mounting knockout(s) on the bottom of the wall housing (see Figure 2). If installing the second transformer for the CD player option, cut a 1-1/2 foot length of power cable to loop between the two transformers. Insert an end of the cable into each of the transformer enclosures through the bottom knockout holes. Use wire nuts to connect the cable to the TE2D transformer BLACK (HOT) and WHITE (NEUTRAL) input wires. Connect the GREEN (GROUND) wire to the cable’s ground conductor. Route the incoming power cable into the TE5D transformer enclosure through the bottom knockout hole. Use wire nuts to connect the incoming power cable to the TE5D transformer BLACK (HOT) and WHITE (NEUTRAL) input wires (and to the cable going to the TE2D transformer if installed). Connect the GREEN (GROUND) wire to the cable(s) ground conductor (see Figure 3). Be sure all power cables entering the transformer enclosure(s) are secured with cable strain reliefs. Tuck the cables into the transformer enclosure(s) followed by the transformer on its mounting plate. Secure the transformer(s) and enclosure(s) to the wall housing with the screws supplied (see Figure 4). 1. 2. 3. 4. 1. 2. 3. 4. 5. 6.

FM reception. The AM antenna is a simple 25-foot length of wire with an in-line ferrite fi lter to reduce interference. The FM antenna is a 25-foot length of coax with a “T” shaped wire dipole at one end that attaches between rafters in the attic. IMPORTANT: Isolate the antenna leads from the intercom station cables by running them through a separate hole in the ceiling plate and through the right hole in the top of the wall housing. If grouped together, the intercom station cables can shield the antenna leads resulting in poor radio reception. Also keep the antenna leads away from metal duct work and aluminum backed insulation, which also can reduce reception. Unroll and examine the 25-foot AM antenna wire. Find the end with the ferrite fi lter (the small object with wire looped through it). The short end of the wire from the fi lter attaches to the dmc1 AM antenna terminal, the long end of the wire is the antenna that goes up into the attic. Fish the long end of the antenna wire up through the right hole in the top of the wall housing, up the stud bay, through a hole in the ceiling plate, and up into the attic. Pull all the wire through until the ferrite fi lter lays inside the wall housing on the right side (see Figure 5). Unroll and examine the FM antenna. The antenna is formed by spreading the red and black wires at the end if the coax. The terminal lug at the end of each wire is for screw mounting the wires outstretched. Fish the connector end of the antenna coax down through the hole in the ceiling plate, down the stud bay, and into the hole on the top right side of the wall housing. Leave about one foot of coax extending into the wall housing (see Figure 5). The antenna adjustment and fi nal installation will be completed during the dmc1 master fi nish-out. ROOM STATION ROUGH-IN At each room station location, nail or screw a Model dmc1HR-5 Room Station Rough-in Ring about 52” above the fl oor level (see Figure 6). Route Cat-5 cable from the master’s wall housing to the room station location. Leave about 12” of extra cable extending at the room station location. Wrap the cable around a nail at the room station location to hold it and protect it from drywall damage. Bring the other end of the cable into the master’s wall housing through the top left wiring access hole or slot. Leave about 12” of extra cable extending at the wall housing.
