Security & Fire Protection Systems/Qualifications to work on existing commercial fire alarm systems


In the state of Tennessee, is a license required to change devices on a commercial fire alarm system, or can a maintenance employee of the company owning the building do it? For example, replacing a defective smoke detector.

If the building is open to the public, your first obligation is to ensure that ANY individual that works on your system (whether they're an employee or not) is fully qualified to perform the service on the system in accordance with the requirements of your Local Jurisdictional Authority.  In Tennessee the first hurdle your maintenance employee would have to pass is certification as a "Qualifying Agent" with the Alarm Systems Contractors Board.  Information is available on their website at

Hope this helps!
