How do you get a Texas low voltage technician license (TDLR)?
Texas has no single low voltage licence β the regulator depends on what the system does. Texas splits this work between regulators rather than issuing one low voltage credential, and that is the thing to understand before applying for anything. The Texas Department of Licensing and Regulation runs electrical licensing, and its electrical law exempts certain limited-energy scopes from electrician licensing rather than creating a low voltage class within it. Security and alarm system installation is regulated separately through the Texas Department of Public Safety's private security programme, and fire alarm work is licensed by the State Fire Marshal's Office at the Texas Department of Insurance. Which agency you answer to therefore depends on what the system does, not on the voltage alone β verify your scope with TDLR, DPS and the State Fire Marshal's Office before quoting work. Whatever the licensing position, structured cabling and limited-energy circuits remain subject to the National Electrical Code β Article 725 for Class 1, 2 and 3 circuits and Chapter 8 for communications circuits β as adopted and amended in Texas, and fire alarm work is normally carved out and regulated separately. The national professional credential is BICSI certification, running from Installer through Technician to the Registered Communications Distribution Designer.
- Establish which regulator your scope answers to in Texas, because low voltage is split by function rather than by voltage alone.
- Contact the Texas Department of Licensing and Regulation and confirm the current classification or certification that matches the systems you intend to work on.
- Build documented field experience under a licensed contractor, which is what any qualifying application will be assessed on.
- Sit the trade and, where the licence is a contracting one, the business and law examination the regulator requires.
- Add BICSI certification for portability, and treat fire alarm scope as a separate credential to be obtained on its own.
Governing law: Texas Private Security Act (Texas Occupations Code, Chapter 1702)

Texas low voltage technician license types: the full TDLR ladder
Low voltage has no journeyman-to-master ladder. What it has is a split between a state contracting or certification credential, a national certification track through BICSI, and a set of adjacent regimes β fire alarm, security, full electrical β that own the scopes sitting either side of it. In Texas, texas has no single low voltage licence β the regulator depends on what the system does.
Low voltage installer / apprentice
The entry point: pulling and terminating cable, mounting devices and testing under supervision. No state credential is normally required to work in this position, and it is where the documented experience for anything further is accumulated.
Low voltage technician
The working level this page covers β installing, terminating, testing and commissioning limited-energy systems. In Texas the relevant regulator is the Texas Department of Licensing and Regulation, and which credential applies depends on what the system does.
Low voltage / limited energy contractor
The credential that lets a business bid and contract limited-energy work in Texas. It is held by a qualifying individual on the company's behalf and normally carries examination, insurance and, in many states, bonding requirements. Employees work under it rather than holding their own.
BICSI Installer and Technician
The national certification ladder: Installer 1, Installer 2 (copper and optical fibre) and Technician, each earned on documented skills and examination. Not a licence and not a substitute for one, but the credential employers and specifiers across the country actually recognise.
RCDD β Registered Communications Distribution Designer
BICSI's design designation, for those specifying telecommunications distribution systems rather than installing them. It requires substantial documented design experience and a demanding examination, and it is frequently written into project specifications.
Fire alarm licensing
A separate regime almost everywhere, usually administered through the state fire marshal and benchmarked against NICET certification in Fire Alarm Systems, with NFPA 72 as the governing code. A low voltage credential does not authorise fire alarm work.
Full electrical licence
The credential on the other side of the boundary. Where a system exceeds the limited-energy scope Texas recognises β line-voltage supply, power circuits, work inside panels β an electrician licence applies instead, and the boundary is set by state rule rather than by a universal voltage figure.
Manufacturer and platform certifications
Access control, video surveillance, networked audio and building-automation manufacturers run their own certification programmes, and specifiers frequently require them for warranty and support reasons. They are commercially valuable and legally irrelevant.
Exact experience hours and fees vary by license type and can change, confirm current requirements on the TDLR Low Voltage Technician program page.

Work out which regulator owns your scope
This is the step people skip, and it is the expensive one. Texas splits this work between regulators rather than issuing one low voltage credential, and that is the thing to understand before applying for anything. The Texas Department of Licensing and Regulation runs electrical licensing, and its electrical law exempts certain limited-energy scopes from electrician licensing rather than creating a low voltage class within it. Security and alarm system installation is regulated separately through the Texas Department of Public Safety's private security programme, and fire alarm work is licensed by the State Fire Marshal's Office at the Texas Department of Insurance. Which agency you answer to therefore depends on what the system does, not on the voltage alone β verify your scope with TDLR, DPS and the State Fire Marshal's Office before quoting work. Get this settled before you pay an application fee, because applying to the wrong agency wastes months.

Confirm where the limited-energy boundary falls
There is no universal voltage line below which work is unregulated. States define limited energy by circuit classification, power and function β and the definitions differ enough that identical work can be exempt in one state and require a full electrical licence in the next. In Texas, confirm the boundary with the Texas Department of Licensing and Regulation in writing, particularly if your work touches line-voltage supply, panel connections or systems integrated with building power.
- 3
Accumulate documented field experience
Every qualifying route rests on demonstrable experience under a licensed contractor: structured cabling to the applicable standards, pathway and space installation, termination and testing with certified results, and commissioning. Keep records signed by the licence holder you worked under, because a regulator assessing a qualifying application will want dates, scope and supervision rather than a rΓ©sumΓ©.
- 4
Sit the examinations the credential requires
Where a contracting credential applies, expect a trade examination on the applicable code and standards and, in most states, a separate business and law examination on contracting, liens and insurance. The trade content sits on the National Electrical Code as adopted in Texas together with the structured cabling standards. Confirm the current examination provider, references permitted and fees with the TDLR β these are revised and should not be taken from any secondary source.

Add BICSI certification and treat fire alarm separately
BICSI Installer and Technician certification, and the RCDD designation for designers, are what travel with you across state lines and what specifiers write into contracts. Fire alarm is the scope to keep separate in your planning: it is regulated on its own almost everywhere, benchmarked against NICET certification in Fire Alarm Systems and governed by NFPA 72, and a low voltage credential does not authorise it.
Does a Texas low voltage technician license transfer to other states?
Limited-energy credentials reciprocate poorly, and the reason is definitional rather than bureaucratic: states draw the boundary between low voltage and full electrical work so differently that there is often no equivalent credential to recognise. Work that is exempt in one state can require an electrician licence in the next. What does travel is BICSI certification, which is national and needs no transfer process, and documented experience, which a regulator assessing a qualifying application will consider. Confirm what the Texas Department of Licensing and Regulation will accept from an out-of-state applicant before assuming any of it carries across.
Reciprocity agreements change, always confirm the current list and requirements on the TDLR Low Voltage Technician program page before applying.
How much does a Texas low voltage technician license cost, and how long does it take?
Fees here are set by the Texas Department of Licensing and Regulation and revised periodically, so treat its published schedule as the source. Budget for the application and examination fees, and β where the credential is a contracting one β for the bond and liability insurance that normally accompany it. BICSI certification is a separate, national cost paid to BICSI, and it is the one that follows you between states.
Texas low voltage examination requirements and licence lookup
What is examined in Texas, and how do you verify a low voltage licence?
Where Texas requires an examination, expect two components: a trade paper on the National Electrical Code as adopted here β Article 725 for Class 1, 2 and 3 circuits, Chapter 8 for communications circuits β together with the structured cabling standards and the systems within your classification, and a business and law paper covering contracting, liens, insurance and the state's licensing statute. Examination providers, permitted references, passing scores and fees are set by the Texas Department of Licensing and Regulation and change, so confirm the current position with the agency rather than relying on a figure published elsewhere.
How to verify a Texas low voltage technician license
Verify a Texas low voltage credential through the Texas Department of Licensing and Regulation, using the tdlr licence search. Check the classification as well as the status: low voltage credentials are scope-limited, and a licence that covers telecommunications cabling may not authorise alarm, access control or fire alarm work. If fire alarm is part of the job, verify that separately with the fire marshal, because it is a different licence under a different authority. GlobalCybers confirms the licence, the classification and any separate fire alarm authorisation before placing a low voltage technician.

Who regulates low voltage work in Texas?
The Texas Department of Licensing and Regulation is the starting point, and it is the body to contact about classifications, applications and the scope each credential authorises. Be aware that low voltage is rarely owned by a single agency: security and alarm systems, and fire alarm systems in particular, are
commonly regulated by different authorities from general limited-energy cabling. Confirm which regime your specific scope falls under before you apply for anything.
