Alarm licensing vs low-voltage licensing: when you need both

Last verified May 23, 2026

One of the most expensive mistakes a growing low-voltage installer makes: assuming their state low-voltage license covers everything, then accepting a job that involves monitored burglar alarm or fire alarm work and finding out partway in that they're operating without the right credential.

The pattern across states

Many states (Florida, Texas, North Carolina, Maryland, Arkansas, Louisiana, Mississippi, New Jersey, Oklahoma, South Carolina, Utah, Alabama, and several others) license LOW VOLTAGE through one agency but issue a SEPARATE credential for monitored alarm services through a different agency.

Why: monitored alarm work historically falls under "private security" regulation - the state wants to know who's listening to alarms and dispatching responders, which is treated as a different regulatory category than just installing low-voltage cables.

How to know which is which

Low-voltage license usually covers:

  • Cabling (data, voice, video, sound)
  • Camera installation (not monitored)
  • Access control installation (cards / readers / locks)
  • Intercom and paging
  • Limited-energy lighting controls

Alarm / fire-alarm license usually covers:

  • Burglar alarm system installation AND/OR monitoring
  • Fire alarm system installation
  • Central station monitoring
  • Sometimes: monitored video surveillance services (varies)

The trap

You can install a camera on a low-voltage license. The moment that camera is monitored by a third party who can dispatch police on a video-trigger event, the regulatory category often shifts to monitored security service, which requires the alarm license.

Same for access control: install the readers on the low-voltage license; if the system feeds a monitored alarm panel that dispatches responders when a door is forced, the alarm license applies.

Bottom line

If you do only install work and never monitor or dispatch, the low-voltage license is usually sufficient. The moment monitoring enters the picture - either you're providing it or you're integrating with a monitoring service that dispatches responders - check whether your state requires a separate alarm license.
