Cautions: Wiring • A qualified electrician must run a 120V AC line to the dmc3-4 retrofit transformers. • Individual wire runs should not exceed more than 350 FEET of wire from any single room station to the dmc3-4 master or 1000 total feet for the entire system.
- Page 6 DO NOT install room stations within 10 feet of other room stations • or the dmc3-4 master unit. This will cause acoustic feedback. DO NOT install room stations in stud cavities with other room • stations or the dmc3-4 master unit. This will cause acoustic feedback.

The use of these or other tools is dependent on the existing intercom system installation: • #2 Phillips screwdriver •... - Page 8 • Wood chisel • Dry wall saw You may not need to use all these tools on each install but having them handy will make the overall installation process easier. Develop the Job Estimate It is critical that you determine the complexity of each retrofit installation prior to developing the job estimate.
- Page 9 If one of these room station to master wire runs has a short, re-run that wire prior to installing the dmc3-4. When replacing wire runs use M&S Systems MS4XSC shielded wire. This wire will work for both 3 and 4-wire installations.
- Page 10 1. If you are replacing the existing master only system with a combination dmc3-4 system you will have to cut the rough-in opening larger to accommodate the larger wall housing.
- Page 11 For the dmc1HC combo wall housing have a qualified electrician loop a power wire from the TE5C transformer enclosure to the TE2C transformer enclosure following the same procedure described above and shown in T E 5 C T E 2 C Figure 5.

(close to the receiver, TV or DVD player for example). Note: the external source wire run to the dmc3-4 must not exceed 50 feet. At this location, attach a single gang box to a wall stud at a center height of normal wall outlets. - Page 15 Make sure the single gang box extends past the wall stud and into the room so it will be flush with the sheetrock when it is applied. Run the Red and Black shielded audio cables (included in the AWPRX) from the master unit location to the AWP location.
- Page 16 Installing the dmc3-4 The dmc3-4 ships configured for a 3-wire retrofit system. If you are replacing a 4-wire system you must change the jumper setup on the dmc3-4 master. The jumper change must be completed before any cables are connected.
