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.
