When panic hardware is required by code
Panic hardware — formally called exit devices under ANSI/BHMA A156.3 — is required by the International Building Code (IBC) and NFPA 101 Life Safety Code on specific egress doors in occupancy categories above a threshold. The trigger conditions vary by occupancy type and occupant load: in Assembly (Group A), Educational (Group E), and High Hazard (Group H) occupancies, panic hardware is required on all egress doors regardless of occupant load. In other occupancies, the threshold is 50 or more occupants in high-hazard or assembly areas, and 100 or more in other cases, though jurisdiction-specific codes may set lower thresholds.
DC, Maryland, and Virginia all adopt IBC and NFPA 101 by reference with local amendments. DC adds fire marshal requirements that are more stringent in certain assembly occupancies; Maryland's building code is closely aligned with IBC 2018; Virginia has adopted IBC 2018 with Virginia-specific amendments. For any commercial installation, confirm the specific local edition and amendments with the permit authority before specifying hardware.
Types of exit devices: touch bar, crossbar, and surface-mounted
Touch bar (also called a rim device): the most common type for single doors. The touch bar spans most of the door width and retracts a latch bolt when pressed. Von Duprin 98/99 Series and Sargent 8800 are the dominant commercial specifications. Touch bar devices are lightweight, durable, and appropriate for doors up to 48 inches wide.
Mortise exit device: integrates the exit device function into the door's mortise lock pocket, providing a combined latchbolt, deadbolt, and exit device in a single door edge case. Common on double-egress doors and applications requiring both panic egress and after-hours security. Corbin Russwin ED7000 and Sargent 80 Series mortise exit devices are standard commercial specifications.
Vertical rod exit device: activates top and bottom latch bolts simultaneously for pair-of-doors applications where a center mullion is absent. Surface vertical rod (exposed rods on door face) and concealed vertical rod (rods run internally through the door) variants exist. Concealed vertical rod provides a cleaner aesthetic and is specified where appearance matters, but requires a hollow metal door with a prepared cutout.
Entry function options: controlling who can enter from outside
Egress code only requires free egress (pushing the bar opens the door from inside). Entry from outside is a separate function that can be configured in several ways: key cylinder (standard keyed cylinder on the outside activates the outside trim or retracts the latchbolt), electrified trim (an electric strike or electrified outside lever allows access control integration without replacing the exit device), and access control-integrated exit devices (electrified panic devices with integrated credential readers).
Dogging function — the ability to hold the latchbolt in the retracted position so the door operates as a push-pull — is available on most touch bar exit devices and is used during business hours on doors that serve high-volume pedestrian traffic. Fire-rated doors cannot use mechanical dogging (holding the latch retracted defeats the fire door's positive-latching requirement); fire-rated exit devices use electrical dogging that releases automatically on fire alarm activation.
Installation: what a proper panic bar install involves
A standard touch bar exit device installation on a steel door takes approximately 45 to 90 minutes including mounting, adjustment, and function testing. The process includes: removing existing hardware, mounting the exit device at the correct height (typically 34 to 48 inches above the finished floor for the bar centerline), cutting or modifying the strike pocket in the frame, installing the appropriate strike (flat lip, curved lip, or electric strike), installing and adjusting the outside trim, and testing the complete operation cycle at least ten times from both sides.
On fire-rated door assemblies, the exit device must be listed for the door assembly's fire rating, and any modification to the door or frame must not void the assembly's label. Hardware installation on a fire door should be documented: photograph the label, photograph the hardware, and retain the installation record.
Exit device adjustments are critical for long-term reliability: the latch bolt must project and retract smoothly without hesitation, the outside trim must not disengage the latch prematurely, and the push force required to activate the exit device must not exceed 15 pounds (IBC requirement for the initial operating force). Improperly adjusted exit devices cause the majority of exit device service calls within the first year after installation.
Common exit device failures and their causes
Latchbolt misalignment: most common failure mode; occurs when a steel door shifts in the frame due to building settling, thermal expansion, or hinge wear. The bolt misses the strike, causing the door to either not latch or require force to latch. Solution: adjust the strike vertically and horizontally to center on the bolt; replace the strike if the current mounting holes are exhausted.
Touch bar stiffness: occurs when the push pad's internal mechanism corrodes or the case binding increases over years of use. Do not lubricate with WD-40 — it attracts dust and accelerates wear. Use a dry PTFE spray or manufacturer-specified lubricant. If the touch bar requires more than 15 pounds of force, the mechanism is worn and the device requires replacement, not further adjustment.

Frequently asked questions
Can I add a lock to a panic bar door to secure it at night?
You can secure an exit device door from outside entry using a keyed cylinder on the outside trim. You cannot block egress from the inside — the panic function must always remain active for interior users. After-hours security is achieved through the outside entry function (keyed cylinder, card reader, or electrified trim), not by disabling the panic device's egress function.
What is the difference between panic hardware and fire exit hardware?
Panic hardware is the general category defined by ANSI A156.3 for devices that provide free egress. Fire exit hardware is the subset of panic hardware that is additionally listed for use on fire-rated door assemblies. Fire exit hardware must meet the requirements of both A156.3 and UL 305 (panic hardware) and UL 10C (positive pressure fire testing). All fire exit hardware is panic hardware, but not all panic hardware is fire exit hardware.
