Public buildings like most industrial and commercial premises are required to meet the conflicting need for both safety and security. Regulations relating to escape from buildings and general safety have made it desirable that doors at exits in public buildings, places of public entertainment, shops, etc, be fitted with ​panic exit devices.
The main purpose of a panic exit device is to give safe and effective escape through a doorway with minimum effort and without prior knowledge of the device.

Exit devices are available in two design styles

The surface vertical rod exit device mounts to the surface of the door. A top and a bottom rod extend the full height of the door and are attached to latch-bolt assemblies. The top latch-bolt assembly engages a strike that can be either surface-applied or mortised into the soffit of the frame. The bottom latch-bolt assembly can latch into a surface-applied or mortise strike in the floor. A latch-track threshold can also serve as a strike to secure the bottom latch-bolt assembly. Similar to rim exit devices, the operating trim extends through the door thickness and engages the lock case of the exit device.
The clearance between the door bottom and the finished floor is an important dimension that needs to be addressed. Depending on the design of the latch-bolt assembly and the strike, the doors may have to be ordered with a non-standard undercut to ensure the latch-bolt can properly engage the strike.

An exit device is a piece of hardware mounted on the push side of a door. It is designed to release a latching mechanism in the event of panic. Exit devices are intended to operate without prior knowledge or training when pressure is applied to horizontal bar or push pad mounted to the door.
Because of their direct effect upon life safety, exit devices are one of the most important hardware items in a building.
Panic Hardware and Fire Exit Hardware are two different types of exit devices, and the proper selection is determined by code requirements.
