Panic Hardware Styles and Types

Here is the second script for your perusal (the first is here, and the third will be posted asap).

Panic Hardware Styles and Types [Draft Script]

Whether panic hardware is required by code or specified for increased security and ease of use, there are three basic styles and four types that are commonly used.

The style of panic hardware selected is dependent on aesthetic requirements, door design, and a few other factors.

  • The touchpad style is the most common style used for modern buildings and allows flexibility when electrified options such as electrified lever trim, electric latch retraction, delayed egress, or controlled egress are required.
  • The crossbar style is often used when aesthetics dictate a minimal silhouette for glass doors, or a vintage look, but electrified options are sometimes limited because of the lack of space in the device to house electronic components. The width of a door’s vertical stiles must be considered when specifying or supplying touchpad or crossbar style panic hardware.
  • Recessed panic hardware reduces the projection of the hardware from the face of the door, but requires a cut-out in the door and may limit the door material to hollow metal.

After the style of panic hardware is selected, one of the four common types of panic hardware is chosen for each door opening, based on functional requirements and whether the door is a single or a pair.

  • A rim panic device is surface-mounted on the door, with the latch projecting from the panic device rather than the door edge. This is the simplest configuration of panic hardware, and the easiest to maintain. Rim panics can be used on single doors, or on pairs of doors in conjunction with a removable mullion. The rim x rim x removable mullion is a very secure application for pairs of doors, because the alignment of the doors is less critical than it is with vertical rod devices. A key-removable mullion makes the mullion easy for authorized users to remove when the full width of the opening is needed.
  • A mortise panic device has a mortise lock body which is installed in the door, with the panic hardware mounted on the door face but controlling the mortise lock. Mortise panics are less commonly used than rim panics, likely because of the more complex door preparation and product design. For fire rated pairs with a 3-hour label, mortise fire exit hardware is sometimes used in conjunction with vertical rod fire exit hardware on the other leaf, but some manufacturers have successfully tested their products for 3 hours with vertical rod fire exit hardware on both leaves or rim devices with a removable mullion.
  • A vertical rod device would typically be used for pairs of doors, and the rods and latches may be surface-mounted on the face of the door, or concealed inside of the door. For concealed applications, there is panic hardware available which incorporates cables instead of rods, for easier installation and maintenance. Vertical rod fire exit hardware is sometimes installed “less bottom rod” (LBR), which allows floor strikes to be omitted along with the bottom rods and latches. An auxiliary pin is typically required for LBR devices to ensure compartmentalization if a fire occurs. This pin is held in a retracted position in the door edge until it reaches a high temperature during a fire, and then it projects automatically to align the doors and protect the opening.
  • A multi-point device combines vertical rods or vertical cables and a rim device, for 3-point latching. These may be used for security purposes, or to meet windstorm requirements.

All of these styles and types are available as panic hardware, listed for use on non-fire-rated egress doors, and fire exit hardware – listed for use on fire-rated egress doors. Additional options for panic hardware include the finish, the type of dogging, electrified options, and trims and controls.

  • Panic hardware is available in a variety of finishes, including architectural plated finishes, stainless steel (when the base material is stainless steel), and powder coat finishes – both standard and custom colors.
  • The act of dogging a panic device holds the latch or latches retracted to allow the door to operate as a push-pull function. This saves wear and tear on the hardware, and makes it easier for building occupants to use. Dogging options include hex-key or key cylinder dogging, and electric latch retraction may also be used to dog a panic device. For fire exit hardware, mechanical dogging is not allowed, but the latch may be dogged electrically if it projects automatically during a fire to provide a positive latch.
  • Many electrified functions are available for panic hardware, including electric latch retraction, electrified lever trim, delayed egress, controlled egress, alarms, switches, or other electrified options to meet the access control and monitoring needs of the facility.
  • There are several other videos in this series that address panic hardware, including the applicable code requirements and the available trims and controls.

Introduction to Codes

Category: VideosLori @ 1:29 am Comments (0)

The last week has been a tough one, and I apologize for any side effects that you may have noticed – either on iDigHardware or in my response time.  Last Monday night, one of my oldest and dearest friends experienced the sudden and unexpected loss of her husband.  Of course my first instinct was to drive across town to see how I could help – except that I live in another country now.  I flew back for a quick trip to Massachusetts, and today I arrived in Carmel, Indiana for some meetings at our corporate headquarters.

Because of this spontaneous travel, things got a little out of whack.  First, it is Wednesday, and today’s Wordless Wednesday post is here.  Second, we are working on the next series of whiteboard animation videos (the others are here), and I would be eternally grateful if anyone has time to give the draft scripts a once-over to see what I forgot to mention.  Here’s the first one…

Introduction to Codes [Draft Script]

Building codes and fire codes help to ensure safety for building occupants. When codes are adopted in a jurisdiction, they become enforceable by law and can be used to hold people accountable in court when code violations result in injuries, fatalities, or property damage. In countries that do not have codes or officials to enforce them, fires and other incidents often result in a very high loss of life.

The first question when trying to research a code issue is – “Which code or standard applies to this project or facility?” There are building codes, fire codes, other codes, and several referenced standards that apply to door openings. Although most codes and standards are revised every 3 years, the newest edition may not be adopted in the project’s jurisdiction right away. The building code that is in effect when the building permit is issued is typically the code used during design and construction. The International Building Code, or IBC, has been adopted by many US states, but states will often modify the IBC and add state-specific requirements so it’s important to be familiar with those modifications.

Prior to 2000, there were 3 model building codes in the US – now called the Legacy Codes:

  • BOCA National Building Code
  • UBC Uniform Building Code
  • SBCCI Standard Building Code

The organizations responsible for these codes worked together to form the International Code Council, or ICC, and to create the 2000 edition of the International Building Code. The IBC has been revised on a 3-year cycle since 2000. The National Fire Protection Association, or NFPA, is responsible for another building code – NFPA 5000 – The Building Construction and Safety Code. Many of the means of egress requirements in NFPA 5000 are consistent with NFPA 101 – The Life Safety Code.

When a building is complete, the fire marshal typically enforces a fire code throughout the life of the building. The International Fire Code, or IFC, and NFPA 1 are commonly-used fire codes in the US. The door-related requirements of NFPA 1 are also found in NFPA 101 – The Life Safety Code. Again, there may be state modifications to the fire code.

Each code also references many standards, which include more detailed information about a particular topic. For example, a state may have adopted the 2015 IBC with state modifications for use during design and construction, and adopt the 2012 editions of NFPA 1 and NFPA 101 as the fire code for occupied buildings. Each of these codes references a different edition of NFPA 80 – Standard for Fire Doors and Other Opening Protectives, so it’s important to know how the requirements vary from one code or standard to the next, and to apply the most stringent requirements.

As new products are developed and technology changes, the code development process is used to gather input from all of the stakeholders with an interest in addressing changes to the code. Proposals are submitted and reviewed and are then approved, disapproved, or modified by a technical committee. There is a public comment period where proposals can be discussed further and more modifications made. Individuals can submit a code change proposal, but working as a group can help to ensure that all aspects are studied. The Builders Hardware Manufacturers Association (BHMA) Codes and Government Affairs Committee, works together on changes to many code requirements that affect door openings.

You can usually determine which code is being used in a project’s jurisdiction by doing an online search for a particular state’s building code or fire code. Reed Construction Data maintains a site that includes the relevant codes and standards for each state, as well as contact information for the code officials. The Reed site can be accessed using the Codes tab on The IBC or IFC Commentary and the NFPA 101 Handbook include additional information that helps to explain the code requirements. These publications are not legally binding, but are often used by Authorities Having Jurisdiction and design professionals to help them interpret the codes.

The term, “Authority Having Jurisdiction” is defined by the National Fire Protection Association as “An organization, office, or individual responsible for enforcing the requirements of a code or standard, or for approving equipment, materials, an installation, or a procedure.” The person responsible for enforcement or approval could be the building inspector, fire marshal, other code officials, an accreditation organization, or other type of inspector, and they may be enforcing different codes – another reason to be aware of the most stringent requirements.

There have been many tragic fires and other incidents that have shaped the codes and specifically impacted the door and hardware industry. Within minutes, more than 600 people were killed by a fire at the Iroquois Theater, largely because of the way the exits were arranged. This fire inspired the invention of the first panic hardware in 1908. The fire at the Triangle Shirtwaist factory killed 146 people because the workers were locked inside. This practice still occurs regularly in some countries. In the Cocoanut Grove fire, 492 people were killed, but fire officials testified that if the exits were available, unlocked and outswinging, then 300 of those lives could have been saved. Even though we now have strict codes and enforcement, these egress problems have not been fully resolved as we saw in the 2003 fire at the Station Nightclub in Rhode Island, where 100 people were killed and many injured.

Code requirements impact many aspects of door openings and can affect the selection of almost every hardware item. Which doors require panic hardware? What hardware must be used on a fire door? Where can delayed egress locks be used? Whether we’re specifying, supplying, installing, or inspecting doors and hardware, it’s our responsibility to speak up if we see situations that we know are not code-compliant and do our best to rectify them.
