The state of florida (dont know about your county/city/etc) defines an electrical license as a person who is licensed to install, design, maintain, etc a power Distribution system. They key word is distribution. Therefore Telecom, Datacom, and some forms of automation are exempt because they are not systems used for distributing power but for signalling other devices.
Florida Statue 489.503(14a) says that if the job has a fair market value of less then $1000, you do not need a low-voltage license. This applies to alarm cabling and the like under 77 volts.
Florida Statue 489.503(14b) further ammends the exemption list for networks used for signalling and communications, and for which their sole purpose or design is not power distribution. So unless your doing alarm installs in florida, you technically dont need a license.
