Commercial Panic Bar / Exit Device Installation
Why this matters
Exit devices (panic bars) are required on egress doors in most commercial / institutional buildings. The IBC and NFPA 101 specify when they're needed and the operational requirements. Customers needing exit device installation, replacement, or service represent a substantial segment of commercial locksmith work. Proper installation is essential for fire safety and code compliance.
When exit devices are required
Per IBC + NFPA 101:
| Building type | Egress requirement |
|---|---|
| Assembly occupancy (>50 people) | Panic hardware on means of egress |
| Educational | Panic hardware |
| High-hazard occupancy | Panic hardware |
| Healthcare (limited) | Specific egress hardware |
| Mercantile (>50 people) | Panic hardware |
| Business | Sometimes required |
| Residential | Generally not required (single-family) |
The customer's specific occupancy classification determines requirements.
Exit device types
| Type | Description |
|---|---|
| Rim exit | Surface-mounted; horizontal bar |
| Mortise exit | Mortise lock + exit bar |
| Concealed vertical rod | Vertical rods inside the door (top + bottom) |
| Surface vertical rod | Vertical rods on the door surface |
| Removable mullion | Center mullion that allows pairs |
| Concealed magnetic | Modern; magnetic with concealed mechanism |
Selection depends on the door type + code requirements + aesthetic.
Major brands
| Brand | Common in |
|---|---|
| Von Duprin | High-end commercial; standard for institutional |
| Sargent | Commercial; mid-tier |
| Schlage | Commercial; widely available |
| Detex | Commercial; specialty |
| Adams Rite | Specialty (storefront, glass doors) |
| Cal-Royal | Cost-effective; smaller commercial |
| Yale | International; commercial |
Each manufacturer offers specific models for each application.
Code requirements
Panic hardware must:
- Open in the direction of egress
- Allow exit with no more than 15 lb of force
- Operate via single-point activation (push bar)
- Not require any other action (key, code, etc.) for egress
- Remain operable under all conditions
These requirements are non-negotiable. Code compliance during installation is the locksmith's responsibility.
Pre-installation survey
Before installation:
- Identify door type (wood, metal, glass)
- Identify door size + thickness
- Identify door frame type (wood, metal, knock-down, welded)
- Identify the existing hardware (what's being replaced)
- Verify egress requirement (which direction must the door swing)
- Identify any electrification (electric strike, magnetic lock paired)
- Verify ADA compliance (lever vs. paddle for accessibility)
- Confirm fire rating of the door (if applicable; specific exit hardware for fire-rated doors)
This information drives the hardware selection.
Selecting the exit device
For each opening:
- Door swing direction: in or out
- Single or pair of doors: pair needs additional considerations
- Indoor or outdoor: outdoor needs weatherproofing
- Indoor traffic level: higher traffic = heavier-duty hardware
- Lockable from outside (with key) or always exit-only
- Special features: alarm, signaling, audit trail
Installation procedure
Step 1: Remove existing hardware
- Remove the existing knob, lock, hinges (if needed)
- Remove the existing strike plate
- Save hardware in case the customer wants to retain
Step 2: Verify door preparation
The door needs:
- Cylinder hole at the correct height
- Latch bolt opening
- Mounting holes per the exit device's template
- Cuts at the correct depth
If preparation is missing, additional work needed.
Step 3: Install the exit device
- Mount the device per manufacturer template
- Secure to the door
- Adjust for proper operation
- Verify the latch engages properly
Step 4: Install the strike
- Position the strike on the door frame
- Secure with proper fasteners
- Verify alignment with the latch
- Test door operation
Step 5: Verify operation
- Operate the device several times
- Verify the latch retracts on push
- Verify the latch engages when door closes
- Verify 15 lb force compliance (manufacturer typically tests; verify in field)
- Test from both sides of the door
Step 6: Adjust as needed
Common adjustments:
- Latch height
- Strike position
- Closer adjustment (if door has a closer)
- Hinge alignment
Pairs of doors
For pairs:
- Active leaf: typically has the exit device + standard latch
- Inactive leaf: has flush bolts or coordinator
- Mullion: removable center post that aligns the doors
- Coordination: ensures the inactive leaf closes first
Pairs add complexity. Both leaves need to satisfy egress requirements.
Fire-rated doors
Fire-rated doors require:
- Fire-rated exit devices (specific listing)
- Fire-rated strike plates
- Fire-rated hinges
- No modifications to the door (other than approved)
- Annual inspection (NFPA 80 requirement for fire doors)
The customer's fire-rated door designation must be matched with fire-rated hardware.
Electrification
Many exit devices are electrified:
| Electrified version | Function |
|---|---|
| Electric latch retraction (ELR) | Latch released electrically |
| Electric strike | Strike released electrically |
| Magnetic lock paired | Maglock secures + exit device allows egress |
| Audit trail | Records each use |
| Alarm | Sounds when used |
| Time-delayed unlock | Delay before opening (high-security) |
Coordinate with access control system if integration is needed.
Common adjustments
After installation:
| Issue | Adjustment |
|---|---|
| Door doesn't latch | Strike position; latch height |
| Excessive force to open | Closer tension; door alignment |
| Latch sticks | Lubrication; clearance |
| Push bar loose | Mounting bolts |
| Closer adjusts wrong | Closer service |
| Pair doors don't align | Coordinator + flush bolt service |
Maintenance
For installed exit devices:
| Activity | Frequency |
|---|---|
| Inspection (force test) | Annual |
| Lubrication | Annual |
| Hardware inspection (loose bolts, etc.) | Annual |
| Closer adjustment | As needed |
| Fire-rated inspection | Annual per NFPA 80 |
Annual service contracts are typical for commercial exit devices.
Customer education
For exit device customers:
- "Your exit door is the means of egress; it must remain operational"
- "Don't block the exit; the bar must be pushable from inside at any time"
- "Annual inspection is required for code compliance"
- "Don't lock the door from outside without verifying egress from inside still works"
