Dmc3-4

•Upon completion of any service or product repair, have the M&S Systems dealer or installer conduct a safety check to ensure the system is in proper operating condition.

•Use only a damp cloth to clean the dmc3-4 master and room stations. Do not use liquid cleaners or aerosol cleaners.

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.

•LABEL all wiring runs. Connecting the wires to the dmc3-4 master, room station or door stations 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 cables.

•DO NOT RUN ELECTRICAL WIRES THROUGH THE DMC WALL HOUSINGS. If you encounter 120VAC wires running through a wall housing during a retrofit you must have a qualified electrician rerun those wires around the wall housing.

•KEEP CABLES AT LEAST 18 INCHES FROM FLORESCENT LIGHT FIXTURES, DIMMER CONTROLS, AND ALL OTHER WIRING. This includes AC wiring, security cable, cordless phone units, and other control wires. These can cause a “hum” or “buzzing” sound.
