Choosing an access control installer in Tennessee
Tennessee checks security wiring twice: alarm firms need state certification, and contractors use a CE-D class for security systems up to 70 volts.

- Firms handling alarm work
- Certification for alarm systems contractors, with a qualifying agent too
- Security wiring contractor class
- Up to 70 volts: CE-D for security systems
- State codes
- Adopted by the State Fire Marshal: the 2021 IBC and the 2017 NEC
- Search for a license
- Credential search from Commerce and Insurance
Check an installer's license
Tennessee Department of Commerce and Insurance (Detection Services Licensing Program; Board for Licensing Contractors) keeps these records. Search by name or license number.

One door job, two programs
Two distinct state programs under the Department of Commerce and Insurance may apply to access control work in Tennessee. The deciding factor is what the doors connect to and the value of the contract.
First comes the alarm systems contractors program, which now sits within the Detection Services Licensing Program. The programme applies to companies that sell, install, maintain or monitor alarms for detecting fire, burglary, intrusion or theft. The other is the Board for Licensing Contractors; that body grants the electrical contractor classifications.
How to earn your alarm contractor credential
This certification cannot be held by one company on its own. A licensed designated qualifying agent must be employed in a management role, and both the company and the agent need the same classifications. The classifications are fire alarm, CCTV (closed-circuit cameras), burglar alarm and monitoring.
A qualifying agent's required proofs appear on the license steps page. An agent needs 3 years of alarm installation work plus a national training certificate, or a post high school degree. Passing a PSI exam is also a requirement for the agent.
- For the company, the fee is $500 and an extra $50 for each classification.
- For the qualifying agent, the fee is $200 and an extra $50 for each classification.
- Any employee who can see alarm plans or records must register no later than 30 days after being hired.
- A certificate of insurance along with the city or county business tax licenses must be turned in by the firm.
Line-voltage work and the CE-D class
Every contractor license in Tennessee includes a classification and a dollar cap. CE-D covers fire detection, burglar alarm, sound, intercom and security systems up to 70 volts, per the board's class outline. There is no trade exam for CE-D, but every new contractor must still pass the Business and Law exam.
When the voltage goes past 70, the class you need becomes CE-J, and a trade exam is required for that one. A Limited Licensed Electrician may handle smaller jobs instead. The LLE license lets you do work below $25,000 per project in areas where permits go through the state Division of Fire Prevention. Check with your local government first, because some towns issue their own licenses.
State codes for classroom locks
You'll find the 2021 International Building Code and the 2017 National Electrical Code, along with amendments, in the State Fire Marshal's adopted codes. One rule applies just to schools. To keep intruders out, you may lock classroom doors as long as the lock satisfies NFPA 101 (2021) Section 15.2.2.2.4.1. Section 39.2.2.2.2 gives college instructional buildings a corresponding rule.
What you pay per installed door
The listed U.S. ranges depend on what the door has now. A Tennessee installer will confirm the price once they inspect the doors.
| On the doors now | Installed, per door |
|---|---|
| Keys only | $1,200 to $2,500 |
| Keypads | $500 to $1,500 |
| Card or fob readers | $500 to $1,500 |
| Not sure | $1,000 to $3,000 |
How do I look up the credentials of a Tennessee installer?
Head to the state-run license and credential search. Type a last name or an organization name, then narrow the list by the board or program you need. Because results update each day, be sure to review the alarm program and the contractors board.
