The Different Types of Door Alarms
Door alarms are used for many different applications. Whether for safety, security, or to save money on energy bills, the different door alarms offer a unique solution to problems faced every day by stores, schools, hospitals, and restaurants.

Exit Alarms
Exit alarms are designed to sound when an unauthorized person exits through a door. A keyholder must come silence the alarm. Exit alarms are typically used on emergency exit doors.

Door Prop Alarms
Door prop alarms allow a door to open and close continuously, but sound when the door is left open longer than the programmed time limit. The alarm silences when the door is closed, and a keyholder is not required to reset the alarm.

Timed Bypass Alarms
Considered both an exit alarm and a door prop alarm, timed bypass alarms allow the door to be freely opened and closed for a set amount of time (for example, the time required to take trash out to a dumpster). After the door is closed, the alarm rearms itself. Timed Bypass Alarms are typically used on restaurant kitchen doors and retail receiving doors.

Door Management Alarms
Typically tied to an access control system, door management alarms provide relay outputs to remote control panels. These alarms usually include detection for intrusion/forced door, and prop/held door. Many can also be used as a stand alone door alarm.

Door Annunciators
A door annunciator sounds when a door opens and stops sounding when the door closes. Similar to a door prop alarm, the door annunciator does not require a key holder to reset the alarm. Door prop alarms can be used as a door annunciator by simply adjusting the timer to the lowest time setting. Like door prop alarms, a cylinder is not required for door annunciators
