Texas Low-Voltage License

Texas DPS-issued license required to install fire alarm, access control, intercom, and security systems.

What is Texas Low-Voltage License?

EIG PRO holds Texas DPS B-04 (security) and BLT (low-voltage) licenses. All technicians performing licensed work carry individual TXDPS-issued IDs. Texas Low-Voltage License should be read together with the project specifications, adopted codes, authority requirements, and referenced standards. A glossary summary explains the construction purpose but does not replace the current published document or a project-specific design review. Editions and local adoption can differ, so the design team should identify the controlling requirement before bidding or installation. For construction administration, document the requirement in drawings, specifications, submittals, RFIs, inspection records, and closeout material as appropriate. When two requirements appear to conflict, request written direction rather than selecting the less restrictive interpretation. That record helps the owner, designer, general contractor, and trade partners understand how Texas Low-Voltage License was applied on the actual project.

Frequently asked questions

Confirm the project specification, applicable codes and standards, approved products, pathway and power needs, testing, labeling, documentation, and responsibility for ongoing operation. Requirements vary by building, jurisdiction, and owner standard, so this article is a planning reference rather than a substitute for the contract documents.

Coordinate it during design and submittals, before pathways and finishes make changes expensive. Verify the installed condition again during testing and closeout, then include the result in the owner’s records.
