If you’re thinking about starting a career in the security or electrical trade, you’ve probably come across two common terms: low voltage license and alarm license. While these may sound similar, they’re not the same — and choosing the right one can affect what kind of work you’re legally allowed to do in Florida.
In this guide, we’ll break down the difference between low voltage and alarm licensing, what each allows you to do, and how to choose the best path for your career.
What Is a Low Voltage License in Florida?
A low voltage license in Florida allows you to install, repair, and maintain electrical systems that operate at less than 98 volts.
These systems are typically related to communication, audio/video, or data transmission — not necessarily alarm or life-safety systems.
Common examples of low voltage work include:
-
Installing network cables or data wiring
-
Setting up home theater systems or intercoms
-
Installing audio, video, or control systems
-
Working on structured cabling in offices or smart homes
Licensing Authority:
Low voltage contractors in Florida are typically licensed under the Electrical Contractor Licensing Board, and the license is sometimes referred to as a Limited Energy Specialty.
What Is an Alarm License in Florida?
An alarm license, on the other hand, specifically allows you to install, service, or monitor burglar and fire alarm systems.
This license is regulated by the Florida Department of Business and Professional Regulation (DBPR) and falls under Chapter 489, Part II of Florida Statutes.
Types of Alarm Licenses:
-
Certified Alarm System Contractor I (EF License)
-
Covers fire and burglar alarm systems statewide.
-
Requires passing a state certification exam and meeting experience requirements.
-
-
Registered Alarm System Contractor II (EF License)
-
Covers burglar alarm systems only within a specific local jurisdiction.
-
Usually requires local registration and working under a certified contractor.
-
Alarm License Work Includes:
-
Installing and wiring security or intrusion systems
-
Setting up fire detection and suppression systems
-
Installing keypads, control panels, and sensors
-
Monitoring and maintaining alarm systems
Key Differences Between Low Voltage and Alarm Licensing
| Category | Low Voltage License | Alarm License |
|---|---|---|
| Regulated By | Florida Electrical Licensing Board | Florida DBPR |
| Voltage Limit | Under 98 volts | Typically under 98 volts (low voltage), but specific to alarms |
| Work Type | Data, audio, video, networking | Burglar and fire alarm systems |
| Examples | CCTV, cabling, audio wiring | Intrusion, fire, and security systems |
| Exam Required | Yes | Yes (for certified level) |
| Scope of Work | General low-voltage | Security and life-safety specific |
Which License Should You Choose?
If your goal is to work on alarm systems, install security equipment, or start a career in the alarm and monitoring industry, the Alarm License is the correct choice.
However, if you plan to focus on general low-voltage installations — such as smart homes, networking, or audio/video systems — then a Low Voltage License may be sufficient.
Many professionals eventually choose to earn both licenses, expanding their skill set and increasing job opportunities.
