Texas does not issue a single low voltage license. The work is split across three regulatory tracks, and the one that applies to you depends entirely on what you plan to install. Security alarms and access control run through the Texas Department of Public Safety. Fire alarm and detection systems run through the State Fire Marshal’s Office at the Texas Department of Insurance. General low voltage cabling for data, telecom, or audiovisual systems is exempt from state electrician licensing under specific conditions. Sorting out which track applies is the first step, because applying to the wrong agency wastes months.
Match Your Work to the Right Agency
Three separate frameworks touch low voltage systems in Texas, and they do not overlap neatly.
- Installing, servicing, or monitoring burglar alarms, intrusion detection, or electronic access control? You register with DPS under the Private Security Act (Occupations Code Chapter 1702), and you must work under a company that holds its own DPS Class B license.
- Installing, testing, or maintaining fire alarm or smoke detection systems? You license through the State Fire Marshal’s Office under Insurance Code Chapter 6002. Several license types exist depending on scope.
- Running only data, telecom, or communications cabling? Texas Occupations Code Section 1305.003 exempts Class 1, Class 2, and Class 3 remote control, signaling, power-limited circuits, fire alarm circuits, optical fiber, and communications circuits from the state’s electrician licensing requirements. If everything you do falls in those categories, you need no TDLR electrician license. If any part of the job connects to line voltage, that portion does require an electrician license through TDLR.1State of Texas. Texas Occupations Code Section 1305.003
What follows covers the two tracks that require an actual license.
Security Alarm and Access Control Registration Through DPS
DPS regulates security-related low voltage work under Chapter 1702. Individual technicians register as alarm installers, alarm system monitors, or electronic access control device installers. You cannot work independently. You must be employed by or contracted through a company holding a Class B company license.
Training and Experience
The initial requirement for an alarm installer is a 16-hour Alarm Level I course, which includes 2 hours on the National Electrical Code for low voltage systems. You can complete it in a classroom or online, and it must be finished with your initial application or within your first 12 months of licensure.2Department of Public Safety. Continuing Education Requirements by Individual Private Security License Type Alarm system monitors take a shorter path focused on monitoring duties and response protocols.
If you want to run the company itself, you need a Class B business license and a designated company representative. That representative must have two consecutive years of full-time work experience in each license category the company applies for.3Department of Public Safety. Company Representative Experience and Examination Information
Application and Fees
Applications go through the Texas Online Private Security (TOPS) portal.4Department of Public Safety. Getting Started with TOPS You submit your employment history, training certificates, and any prior disciplinary actions from other licensing boards.
The fees are modest for individuals and heavier for companies:
- Alarm installer, alarm system monitor, or electronic access control device installer: $37 for the original application and each renewal.
- Class B company license (needed to operate as an alarm contractor): $412.
- FBI fingerprint check: $28.25, billed separately.5Department of Public Safety. Private Security Fee Schedule
Fire Alarm Licenses Through the State Fire Marshal
The State Fire Marshal’s Office issues five distinct license types under Insurance Code Chapter 6002. Qualifications get progressively steeper as the scope of work widens.
- Residential fire alarm technician. Covers installing and servicing detection devices in one- and two-family homes. Requires an approved training course, no NICET certification.
- Fire alarm technician. Covers installing, inspecting, servicing, testing, and certifying fire alarm systems in any building type. Applicants pass NICET or ESA testing in fire alarm work elements, or the State Fire Marshal’s qualifying test.
- Fire alarm monitoring technician. Limited to monitoring. Requires the State Fire Marshal’s technical qualifying test.
- Residential fire alarm superintendent. Authorizes planning, installing, and certifying detection systems in one- and two-family residences. Applicants pass the Fire Marshal’s statutes and rules test plus a residential test. The technical exam is waived by NICET Level II or ESA Level II Fire Alarm Technician certification.
- Fire alarm planning superintendent. The broadest license, covering planning and certifying fire alarm systems in any occupancy. Requires NICET Level III, ESA Level III Fire Alarm Designer certification, or a Texas Professional Engineer license.
The planning superintendent credential is what lets you design fire alarm systems for commercial buildings and large facilities. The NICET Level III requirement is a real hurdle; most technicians spend years building the project experience needed to pass that exam.6Texas Department of Insurance. Fire Alarm Registration, License, and Test Information
All fire alarm applicants must pass a qualifying test and complete fingerprinting before TDI will process the application. Technical certificates such as NICET score reports, ESA certifications, or proof of a Texas PE license must accompany the application.
Fire alarm companies also carry liability insurance. Minimum coverage amounts are set by regulation under 28 TAC Chapter 34, and the exact figures can vary based on the services provided. Build both the licensing fees and an insurance policy into your startup budget.
Background Checks and Disqualifying Offenses
Both tracks require fingerprint-based criminal background checks. Private security applicants submit fingerprints electronically through IdentoGO. After you submit your application and payment through TOPS, IdentoGO emails you within about an hour with instructions to schedule an appointment at an enrollment center.7Department of Public Safety. Fingerprinting Instructions Fire alarm applicants go through a similar process managed by TDI.
DPS lists disqualifying criminal offenses under 37 Texas Administrative Code Section 35.4. The categories are broad: assault, burglary, theft, fraud, robbery, sexual offenses, arson, and criminal homicide, among others. Attempting or aiding any of these counts the same as committing them directly.8Department of Public Safety. Private Security Administrative Rules
Waiting periods depend on severity:
- Felony conviction for a listed offense: disqualifying for 10 years from the date you completed your sentence.
- Class A misdemeanor conviction for a listed offense: disqualifying for 5 years from the date you completed your sentence.
- Felony or Class A misdemeanor unrelated to the occupation: disqualifying for 5 years from the date of commission.
If DPS denies your application based on the background check, you receive a letter explaining the reasons.9Department of Public Safety. Eligibility/Compliance Questions Applicants arrested for a felony or Class A or B misdemeanor must submit court documents with the application even if the case was resolved favorably.
Renewals and Continuing Education
Security Licenses
DPS private security registrations renew every two years. Alarm installers complete 8 hours of continuing education in alarm subjects before each renewal, including 1 hour on the National Electrical Code for low voltage systems. Monitors need 4 hours focused on monitoring duties. Electronic access control device installers complete 8 hours, with 7 hours in their specialty and 1 hour on ethics.2Department of Public Safety. Continuing Education Requirements by Individual Private Security License Type
CE only counts if completed within the two-year period before expiration. Late fees climb fast. An alarm installer renewal up to 90 days late costs $52 instead of $37, and renewals more than 90 days late jump to $67. A Class B company license more than 90 days overdue costs $812 rather than $412.5Department of Public Safety. Private Security Fee Schedule
Fire Alarm Licenses
TDI sends a renewal notice 90 days before your fire alarm license expires. After the initial renewal, the cycle is every two years.6Texas Department of Insurance. Fire Alarm Registration, License, and Test Information Confirm current continuing education hours directly with TDI when your renewal notice arrives; the requirement is set by administrative rule and can change.
Penalties for Working Without a License
Texas takes unlicensed low voltage work seriously, and the two tracks differ sharply in what they can do to you.
For security alarm work, installing without a DPS license can bring a civil penalty of up to $10,000 per violation. The same penalty applies to anyone who knowingly hires or contracts with an unlicensed person for work that requires a license. The state must show the person received at least 30 days’ notice of the licensing requirements before imposing the penalty.10State of Texas. Texas Occupations Code Section 1702.381 – Civil Penalty
For fire alarm work, the consequences are harsher. Installing without a license is a Class B misdemeanor, meaning a criminal charge rather than only a civil fine. Each day of unlicensed work counts as a separate offense. On top of the criminal charge, the insurance commissioner can impose an administrative penalty of up to $10,000 per violation, again with each day counting separately.11State of Texas. Texas Insurance Code Chapter 6002
Contractors carry the same exposure when they bring unlicensed technicians onto a job. Keeping every registration on your crew current is a legal issue, not just a paperwork one, and a lapse can put the company license itself at risk.
