An Exit Device is a door lock that prevents a occupant from entering or exiting a room if an emergency occurs. These devices are essential to the safety of a building and provide accessibility. There are many types of exit devices, including mechanical, electrified, and glass doors.
Exit devices are commonly classified as either Panic Hardware or Fire Exit Hardware, and are physically labeled accordingly. The difference between them is only apparent in appearance and function. These types are also visually distinguishable. There are four main types of exit devices: Push Bars, Crash Bars, and Levers. A panic bar is the most common type of exit device. It is an automatic door lock that can prevent a hazard by disabling the occupants of a room from entering.
Vertical Rod Exit Devices - These devices are commonly used on double doors, although they may also be found on single doors. A panic bar is pushed to release the rods. Surface Vertical Rod (SVR) and concealed vertical rod (CVR) devices are available. Both types are UL and ADA compliant. They can be installed on most door facings. When purchasing a CVR or an ADA-compliant Exit Device, you need to consider the installation process.
