An exit alarm is an electronic device that activates an alarm when a door is opened. There are several types of exit alarms, including (but not limited to) door alarms, door prop alarms, and door management alarms.

There are many alarms on the market, and knowing your application needs is crucial for deciding which alarm to get.
