Exit Alarm Overview

Updated on October 22, 2011

Exit alarms sound an alarm when a person opens the door to go out. Typically they are put on doors with no access from the outside, for example, the back door of a store in a mall, however, many can be temporarily deactivated for entry from the outside.

Exit Alarms are manufactured as stand-alone alarms with no lock or as alarms that are part of a locking device.

Alarmed Locking Devices

The Arm-A-Dor (top right) is an exit only exit device available with a battery operated or externally powered alarm. It's disadvantage is that if offers no means of entry from the outside.
