South Carolina Low Voltage License Requirements (2026)
By Gabriel Giner, Editor · Reviewed 2026-06-02 · CLR Editorial Review Desk
South Carolina splits low-voltage licensing between two agencies. The State Law Enforcement Division (SLED) Regulatory Services licenses every burglar alarm, fire alarm, CCTV, and access-control business statewide under the South Carolina Alarm System Business Act (S.C. Code Ann. §40-79) and requires a designated qualifying manager with three years of experience and passing the SLED Alarm Business examination. Structured cabling and general telecommunications contracting falls under the South Carolina Contractor's Licensing Board within the Department of Labor, Licensing and Regulation (LLR) specialty classification ST-LV (Low Voltage) under S.C. Code Ann. §40-11 for projects valued at $5,000 or more. Fire alarm contractors must additionally hold the SC State Fire Marshal Fire Alarm Inspector certification for acceptance testing under S.C. Code Ann. §23-9-60.
Regulatory Oversight
South Carolina Contractor's Licensing Board (SCCLB) administers and enforces this credential under the authority of South Carolina Code of Laws Title 40 Chapter 11 (Contractor's Licensing Act). The South Carolina Contractor's Licensing Board sits within the SC Department of Labor, Licensing and Regulation (LLR) and licenses general and building contractors statewide. The Board administers Title 40 Chapter 11, sets financial group limits (Group I–V), approves PSI examinations, and conducts disciplinary proceedings.

Who May Apply
To qualify, an applicant must have reached age 21 and hold a valid Social Security Number. No South Carolina residency requirement, but the SLED Alarm Business license must designate a qualifying manager who is a regular employee.
Good moral character
SLED and LLR both conduct fitness reviews. Felony convictions within the last ten years are reviewed individually under S.C. Code Ann. §40-79-40 and may result in denial.
Background investigation
Mandatory fingerprint-based SLED and FBI background check for the SLED qualifying manager and every registered Alarm Employee under §40-79-80.
Required Experience and Education
The applicant must document and verify at least three years of full-time experience designing, installing, servicing, or supervising burglar alarm, fire alarm, or electronic security systems under a licensed SLED Alarm Business for the SLED qualifying manager credential, or equivalent military / federal experience. Keep payroll, tax, project, or supervisor records to support the claim, as the board can request proof for any period within its lookback window.
Accepted proof of experience or eligibility
- SLED Experience Verification Form signed by each supervising qualifying manager
- W-2 statements or 1099 records covering the three-year qualifying period
- NICET Fire Alarm Systems Level II certificate
- Manufacturer training and BICSI installer certificates
Education substitution
An accredited two-year electronics or fire protection engineering associate degree substitutes for one year of the SLED qualifying manager experience requirement under SLED Regulation 73-40.
Examination Requirements
The licensing examination is delivered by PSI Services LLC under contract to SLED; Prov Inc. for the LLR Contractor Licensing Board. All of the following parts must be cleared prior to issuance:
- SLED Alarm Business Qualifying Manager Examination — burglar and fire alarm, CCTV, access control, SC statutes — 100 questions, 180 minutes, passing score 70%
- LLR Contractor Licensing Board ST-LV Specialty and Business and Law Examination — 80 questions, 180 minutes, passing score 70%
Examination fee: $150 SLED qualifying manager exam fee plus $90 LLR specialty trade exam and $65 Business and Law exam.
Retake policy: Failed SLED exams may be re-taken after 30 days by paying a new $150 fee. LLR exams follow standard Prov retake rules with a 30-day waiting period.
Insurance and Financial Requirements
The cited state source set does not require a contractor license surety bond for this credential. Contractors should still confirm project-specific bond, permit-bond, or public-works bond requirements before bidding.
General liability
SLED requires every Alarm System Business to carry a minimum $100,000 commercial general liability certificate under §40-79-80. LLR requires $500,000 minimum for ST-LV specialty contractors on projects exceeding $200,000. Commercial owners contractually require $1,000,000/$2,000,000.
Workers' compensation
Workers' compensation is mandatory for any South Carolina business with four or more employees under S.C. Code Ann. §42-1-360.
Additional financial requirements
LLR requires a $5,000 net worth statement for ST-LV specialty contractors with project limits above $200,000.
Licensing Fees
| Fee | Amount |
|---|---|
| Application (non-refundable) | $450 |

Keeping the License Current

The NASCLA Accredited Examination is not accepted by South Carolina for this classification.
| Reciprocal State | Accepted Exam | Conditions |
|---|---|---|
| North Carolina | Alarm exam waived | Bilateral SLED-NC Alarm Systems Licensing Board reciprocity for active qualifying managers with three years active status. |
| Georgia | Alarm exam waived | Bilateral SLED-GA Board of Private Detective and Security Agencies reciprocity. |
South Carolina SLED reciprocates with North Carolina and Georgia for Alarm Systems Business credentials held actively for three years. LLR ST-LV classification does not reciprocate - out-of-state applicants must pass the Prov trade and Business and Law exams.

Application Process, Step by Step
- Confirm scope. Burglar alarm, fire alarm, CCTV, access control = SLED Alarm System Business license. Structured cabling, general low-voltage over $5,000 = LLR ST-LV specialty. Fire alarm acceptance testing = SC State Fire Marshal certification.
- Document three years of qualifying experience. Compile SLED Experience Verification Forms covering three years of supervised alarm or electronic security work.
- Submit the SLED Alarm Business application. File the application with the $450 fee, $100,000 liability certificate, qualifying manager designation, and fingerprint-based SLED and FBI background clearance.
- Pass the SLED qualifying manager examination at 70%. Score 70% or better on the 100-question SLED qualifying manager exam covering burglar/fire alarm technical and SC statutes.
- Register every alarm employee with SLED. Each installer must hold a SLED Alarm Employee Registration issued after fingerprint clearance under §40-79-80.
- Apply for the LLR ST-LV specialty contractor license. File the LLR Contractor Licensing Board application with the $135 fee, $5,000 net worth statement, and Prov trade/business exam eligibility letter (for projects over $5,000).
- Pass the Prov ST-LV trade and Business and Law exams at 70%. Score 70% or better on both the 80-question ST-LV specialty trade exam and the 50-question Business and Law exam.
- Register with the State Fire Marshal for fire alarm work. File the SC State Fire Marshal Fire Alarm Inspector certification with NICET Level II evidence for commercial fire alarm acceptance testing.

Frequent Application Errors
Drawn from the board instructions and sources cited on this page, the pitfalls below are the ones most likely to slow down or sink a South Carolina Low Voltage application.
Operating without the SLED Alarm Business license
Any burglar alarm, fire alarm, CCTV, or access-control business must hold a SLED Alarm System Business license. Operating without one is a felony under §40-79-40 and voids every contract.
Unregistered alarm employees
SLED fines agencies $1,000 per unregistered worker. Every installer must hold an Alarm Employee Registration issued after fingerprint clearance before being placed on a job.
Assuming SLED covers cabling
The SLED license covers alarm and electronic security only. Structured cabling projects over $5,000 additionally require the LLR ST-LV specialty classification.
Missing the State Fire Marshal certification
The SLED license authorizes the business; the SC State Fire Marshal separately certifies Fire Alarm Inspectors for acceptance testing. Commercial fire alarm work without the SFM certification blocks occupancy.
Letting the qualifying manager leave
The SLED Alarm Business license is tied to a specific qualifying manager. Departure without naming a replacement within 30 days automatically suspends the license under §40-79-40.
