Where panic hardware is required, the actuating portion of the device (touchpad or crossbar) must be at least half the width of the door leaf.

As we’ll discuss later in this article, electric latch retraction may be used to electrically dog the latch on fire exit hardware, but the latch must project automatically upon actuation of the fire alarm. The dogging feature, which allows the latch to be manually held retracted, is not supplied on fire exit hardware because fire doors must have an active latchbolt to keep the door closed and latched during a fire.

Fire exit hardware is a type of panic hardware that is tested and listed for use on fire door assemblies, in addition to the UL 305 listing. Panic hardware is listed in accordance with UL 305 – the standard for panic hardware, and is used on doors that are not fire rated.

This does not apply to doors which require panic hardware because of the National Electrical Code, as this code only requires panic hardware on doors within 25 feet of the required working space. Keep in mind that when an application requires panic hardware, all of the doors in the means of egress from that room or area will typically require panic hardware, including the exit access, the exit, and the exit discharge. If a door is not equipped with a latch or lock (push/pull application), the door is not required to have panic hardware. The AHJ may request panic hardware in other instances if he or she believes that a particular hazard exists and panic hardware is required for life safety. The IBC includes requirements for panic hardware on some electrical rooms. Panic hardware or fire exit hardware may also be required for mechanical rooms such as boiler rooms, incinerator rooms, furnace rooms, and refrigeration machinery rooms.

Previous editions of NFPA 70 include slightly different requirements for panic hardware on electrical rooms. equipment with less than 600 volts but more than 800 amps, with overcurrent devices, switching devices, or control devices, and.In addition to Assembly, Educational and High Hazard occupancies, the 2014 edition of the National Electrical Code (NFPA 70) requires panic hardware or fire exit hardware on doors within 25 feet of the required working space for rooms housing: Note that the codes also include an exception for the main entrance of certain occupancies, including Assembly occupancies of a limited size, which may sometimes be equipped with key-operated locks instead of panic hardware. Since the occupant load is determined by the area of a room divided by a required number of square feet per person (the factor varies by occupancy type), this means that panic hardware is required for much smaller rooms when referencing the newer editions of the IBC. Beginning with the 2006 edition, the IBC requires panic hardware on these occupancy types with an occupant load of 50 people or more (and all High Hazard occupancies). In the 20 editions of the International Building Code (IBC), panic hardware was required on egress doors serving Educational and Assembly Occupancies with an occupant load of 100 people or more (as well as certain High Hazard occupancies). Panic hardware is only required by code for a few occupancy types. In an effort to help bring some much-needed clarity to this issue, we’ll explore the code requirements that drive the use of this hardware as well as some of the more common exceptions and restrictions you should be aware of when specifying these devices.

Complicating matters further, panic hardware is frequently combined with electrified options such as electric latch retraction, delayed egress, and controlled egress that carry with them additional restrictions and requirements. The Life Safety Code (NFPA 101) and the International Building Code (IBC) both include requirements pertaining to panic hardware, but those requirements vary depending on which publication and edition are being enforced in a particular jurisdiction. But despite its popularity, the question, “When is panic hardware required by code?” is one that many specifiers continue to struggle with because there isn't a simple answer to this seemingly simple question. Because of its durability and ease of use, panic hardware is commonly installed in places where it isn’t required by code. Panic hardware, also known as an exit device, is designed to provide building occupants fast and easy egress in an emergency.
