Direct answer
What you need to know
OnSiteO does not verify contractor licenses. If your site or your state requires a licensed low-voltage contractor, put it in the job and ask the technician for their license number before you choose them. Then check it with the official source: Florida DBPR, the Ohio Construction Industry Licensing Board, or your local Indiana building department.
Florida
Florida licenses alarm and electrical work through the Electrical Contractors' Licensing Board (DBPR). An Alarm System Contractor I (EF) may do all types of alarm systems; an Alarm System Contractor II (EG) covers all alarm systems except fire. Specialty contractor licenses cover limited segments of electrical work.

Ohio
The Ohio Construction Industry Licensing Board licenses electrical, HVAC, refrigeration, plumbing and hydronics contractors for commercial work; it has no separate low-voltage license. The State Fire Marshal certifies people who install or service fire protection equipment, and cities may add their own rules.

Indiana
Check with the building department for the city or county where the site is. In Fort Wayne and Allen County, the Allen County Building Department works with the licensed and registered contractor awarded a permitted project; ask it which license and permit your project needs.
