The birthplace of country and blues has become far more than the agrarian state it once was. Tennessee's major urban centers are important cities with significant economies. And Tennessee fully supports economic growth and development -- which may be why it doesn't impose too much regulation on business. Unlike many states, Tennessee gives counties and cities significant leeway to decide on their own regulations -- often making state licenses required only at the discretion of local jurisdictions.
In Tennessee, a communication and low voltage systems contractor installs, services and maintains all types of communication and low voltage systems which are energy limited and do not exceed 91 volts. These systems include, but are not limited to telephone systems, sound systems, cable television systems, closed-circuit video systems, satellite dish antennas, instrumentation and temperature controls, and low voltage landscape lighting. Low voltage fire alarm systems are specifically not included in this section.
