• 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.
