A crash bar (also known as a panic exit device, panic bar, or bump bar) [1] [2] is a type of door opening mechanism which allows users to open a door by pushing a bar. While originally conceived as a way to prevent crowd crushing in an emergency, crash bars are now used as the primary door opening mechanism in many commercial buildings.
Doors generally have at least one fixed handle, usually accompanied with a latch (see below). A typical "handle set" is composed of the exterior handle, escutcheon, an independent deadbolt, and the interior package (knob or lever). On some doors the latch is incorporated into a hinged handle that releases when pulled on. See also:
Metal fire-resistance rated door with a lockset consisting of a locking latch bolt operated by lever handle with an escutcheon that encompasses the locking mechanism.. A lockset (alternatively lock set) is the hardware and components that make up the locking or latching mechanism that can usually be found on a door or other hinged object but can also include sliding doors and dividers. [1]
Any fire doors which are normally held open must automatically close and lock when a fire is present in the building. The function of an emergency exit rim device (crash bar or panic bar) will permit escape through a fire door, however it must re-latch once released. (A fire door must not be "dogged" to disable its latch.)
Historically, such locks were intended for use at night-time, hence the name. [5] The keyless egress that they offer is a valuable fire safety measure, but may be a security risk if breaking a glass panel (usually in the door) or a nearby small window allows an intruder to reach the knob inside and open the door from the outside.
