Exit devices come in mortise, rim, surface, and concealed vertical rod exit device configurations that can provide electrified functions such as electric latch retraction, locking (and unlocking), dogging, exit alarms, and delayed egress. Exit devices are categorized as either panic or fire exit hardware and have a touch bar, cross bar, or integral device design. Fire exit hardware must be labeled and tested for use on fire-rated assemblies and some features of standard panic hardware cannot be used on fire-rated openings.

Exit alarms – Exit devices can be configured with an exit alarm to sound when the door is opened to deter unauthorized use, such as on emergency exits.
