7720ULF
UL Listed Radio Transmitter
SPECIFICATIONS:
ORDERING:
Installation:
The 7720ULF should be mounted indoors, in an area that is
easily accessible. Before mounting the panel to the wall, the
best location to install the panel can be determined by use of
the 7715DF installation tool. If it is necessary to remotely
mount the antenna avoid obstructions such as metal ducts,
pipes, foil backed insulation, etc. as these will adversely affect
Transmission. When mounting the antenna remotely, the
coaxial cable must be inside conduit.
