Have a qualified electrician run a dedicated
120VAC/60Hz line with ground connection
from the power panel to the wall housing as
show in figure 3. The dmc1 requires a
dedicated power source to assure no
interference from other equipment caused
by looped power circuits. The ground is
necessary for proper
radio reception.
Place transformer enclosure from the inside
of the wall housing into the transformer
enclosure opening at the bottom of the wall
housing as shown in figure 4.
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 figure 5.
Antennas
Isolate the antenna leads from the intercom cables by running them
through a separate hole in the ceiling plate and in the top of the
wall housing as shown in figure 6. If grouped together the intercom
cables can shield the antenna leads resulting in poor radio
reception. Keep the antenna leads away from metal ductwork and
aluminum backed insulation. These can also shield the antenna
leads.
