What Is an Exit Alarm and Why Do You Need One?
An alarm device mounted to an emergency exit door that sounds a loud alarm when the door is opened. The alarm deters unauthorized use of emergency exits (employees sneaking out for smoke breaks, customers bypassing checkout). The door still opens freely, meeting fire code, but the alarm alerts staff.
Retail stores use exit alarms to prevent shoplifting. Warehouses use them to control which doors employees use. Schools use them on perimeter doors. According to the National Retail Federation, exit door shoplifting accounts for 15% of all retail shrink. An exit alarm is a cheap deterrent.

Surface-mounted alarm bar (Detex ECL-230D): $250-$400. Stand-alone door alarm (magnetic sensor type): $150-$250. Includes hardware, wiring (if needed), and testing.
Does an exit alarm lock the door?
No. The door must open freely for fire code compliance. The alarm simply sounds when the door is used. After 15-30 seconds (or when reset by authorized personnel), the alarm stops and the door can close and reset.
Can the alarm be silenced with a key?

Are exit alarms fire code compliant?
Yes, when properly installed. The door must remain operable from the egress side at all times. The alarm is an alert system, not a locking device. Fire marshals approve them.
