- Mechanical devices such as deadbolts or locks
- Operators for opening or closing commercial gates
If your access control system includes electronic locks, card readers, or monitoring capabilities, you need Burglar Alarm classification licensing.

The Tennessee Alarm Systems Contractors Board issues licenses in these classifications:
- Burglar Alarm - Access control, intrusion detection (required for access control)
- Fire Alarm - Fire detection and notification
- CCTV - Video surveillance
- Monitoring - Central station services
Qualifying Agent Requirements
Each company must employ a Designated Qualifying Agent who:
- Holds post-secondary degree from an accredited institution, OR
- Holds approved certification with 3+ years of alarm industry experience
- Passes examination for each classification
- Oversees quality of operations in a management position

IBC Egress Requirements for Access Control
Hamilton County enforces the International Building Code (IBC) for egress door requirements. Access control installations must comply with Section 1010 regarding door operations and egress.
Fundamental Egress Principle
The 2021 IBC Commentary states: "Egress doors are permitted to be locked to prevent entry, but must be capable of being unlocked and readily openable from the side from which egress is to be made."
Sensor Release Requirements (IBC Section 1010.2.11)
For electromagnetic locks released by sensors on egress doors:
- Sensor must detect approaching occupant and unlock door automatically
- Manual release device required, labeled "PUSH TO EXIT"
- Manual device mounted 40-48 inches above floor, within 5 feet of door
- Door must remain unlocked minimum 30 seconds after manual activation
- Fire alarm or sprinkler activation must automatically unlock door
- Door remains unlocked until fire panel is reset
Delayed Egress (IBC Section 1010.2.12)
Delayed egress locking systems are permitted in certain occupancies:
- Standard delay: up to 15 seconds
- Extended delay (where approved): up to 30 seconds
- Local alarm must sound during delay
- Building must have automatic sprinkler or smoke/heat detection
Permitted occupancies for delayed egress: Group B, F, I, M, R, S, U, and Group E classrooms with occupant load under 50.
Hardware Requirements
| Hardware Type | Egress Requirement | Code Reference |
|---|---|---|
| Electric strike | Free egress via door hardware | IBC 1010.2 |
| Magnetic lock | Sensor release + manual override | IBC 1010.2.11 |
| Electric mortise lock | Free egress via lever | IBC 1010.2 |
| Delayed egress | 15-30 second delay + alarm | IBC 1010.2.12 |
Fire Alarm Interface Requirements
Access-controlled egress doors require fire alarm system interface:
- Building must have fire alarm or sprinkler system
- Fire alarm activation must unlock access-controlled doors directly
- Doors remain unlocked while alarm condition is active
- System cannot reset until fire panel is reset
Coordinate with the Chattanooga Fire Prevention Bureau at (423) 643-5618 for fire alarm interface requirements.

Residential vs Commercial Projects
Residential Installations
Residential access control (smart locks, video doorbells, residential card access) may not require permits when:
- Not affecting egress from dwelling
- Using battery-powered or plug-in devices
- No fire alarm integration required
- No structural modifications needed
Commercial Installations
Commercial projects typically require permits due to:
- Egress door code compliance requirements
- Fire alarm interface obligations
- Life safety code enforcement
- ADA accessibility considerations
Commercial access control plans may require involvement of an architect or engineer for complex installations.
Pro Tips from Experienced Contractors
- Understand egress before installation: Hardware selection must support required egress method. Do not install magnetic locks without proper sensor release and manual override.
- Verify fire alarm interface early: Coordinate with the fire alarm contractor to ensure proper relay outputs and wiring for door release on alarm activation.
- Document door schedules: Create detailed hardware schedules showing each door, hardware type, egress method, and fire alarm integration.
- Label push-to-exit buttons: Ensure all manual release devices are properly labeled per code requirements.
- Test backup power: Access control panels should maintain door functionality during power outages per life safety requirements.
