What Is a Emergency Exit Door Alarm?
Exit door alarms sound an audible alert when a designated door is opened, ranging from simple surface-mounted battery alarms that clip onto any door for basic deterrence, to alarmed exit hardware integrated directly into a panic bar or exit device, to delayed egress locks that briefly delay the door's release while still sounding an alarm and complying with life-safety code requirements for emergency egress within a set time limit.
Fire and life-safety code (such as NFPA 101) strictly governs which doors can use a delayed egress lock and under what conditions — these systems must release automatically on fire alarm or sprinkler activation and cannot delay egress beyond a code-specified maximum (commonly 15 seconds), so a delayed egress alarm lock must be installed and configured to meet the applicable code, not selected purely for security convenience. Decibel rating and reset method (key, keypad, or automatic) are chosen based on the deterrence and administrative control needed.

| Spec | What It Means | Why It Matters |
|---|---|---|
| Alarm Mechanism | Simple audible alarm vs. delayed egress lock | Delayed egress locks are code-restricted and must comply with life-safety egress time limits |
| Mounting Type | Surface-mount standalone vs. integrated exit device | Integrated units mount directly to panic bars/exit hardware; standalone units retrofit to any door |
| Power Source | Battery-powered vs. hardwired | Hardwired units avoid battery replacement but require electrical installation |
| Decibel Rating | Commonly 85-110+ dB | Higher decibel ratings improve deterrence and immediate notification in larger or noisier spaces |
| Fire Alarm Integration | Standalone vs. tied to building fire alarm system | Delayed egress locks must release automatically on fire alarm activation per code |

FAQ
Emergency Exit Door Alarms Questions, Answered
What's the difference between a simple door alarm and a delayed egress lock?
A simple door alarm sounds when the door is opened but does not restrict or delay the door from opening — anyone can exit immediately, and the alarm is purely a notification and deterrent. A delayed egress lock briefly delays the door's release (commonly up to 15 seconds under most codes) while also sounding an alarm, providing a stronger deterrent, but is subject to strict fire and life-safety code requirements governing where it can be used.
Where are delayed egress locks not permitted?
Code restrictions vary by jurisdiction and occupancy type, but delayed egress locks are generally restricted from primary means of egress in high-occupancy or high-risk-population buildings, and are never permitted to delay egress beyond the code-specified maximum time or to remain locked during a fire alarm or sprinkler activation — check applicable NFPA 101 and local fire code requirements before installing on any life-safety-critical exit.
Do exit door alarms require fire alarm system integration?
Delayed egress locks generally must be tied into the building's fire alarm and sprinkler system so they release automatically and immediately upon activation, per life-safety code. Simple audible-only door alarms used purely for security notification don't have this requirement, though check local code for any specific requirements applicable to your occupancy type.
Can a standalone battery-powered alarm be added to an existing exit door without rewiring?
Yes — surface-mount battery-powered door alarms are designed as retrofit devices that clip or mount to an existing door and frame without electrical wiring, making them a practical option where a hardwired system isn't feasible or a full exit device replacement isn't warranted. They're generally used for basic deterrence rather than code-required delayed egress applications.
How is an exit alarm reset after it's triggered?
Reset methods vary by product — key-reset alarms require a physical key to silence and reset, keypad-reset units use a code, and some simpler models reset automatically once the door is closed again. Choose the reset method based on the level of administrative control needed over who can silence the alarm.
