Common Types of Exit Door Alarms
Most exit alarms fall into three main categories:
- Standalone door alarms: Battery-operated units mounted directly on the door. They sound when the door is opened without authorization.
- Delayed egress alarms: Integrated with panic bars, these delay opening by 15 seconds, giving staff time to respond before the alarm activates.
- Integrated access control systems: These alarms tie into electronic access control or fire alarm systems and are often used in schools, hospitals, and government facilities.
Choosing the right type depends on your building layout and compliance needs. If you're outfitting new doors, see our tips on which emergency exit hardware your business needs.
How Exit Door Alarms Work
Exit door alarms are triggered by movement—either when the panic bar is pushed or the door is opened without disarming the system. Many are armed via a keyed cylinder, digital keypad, or integration with the main building security system.
Once triggered, they emit a loud siren to draw attention. Some models also include strobe lights or send alerts to central monitoring systems.
To ensure full door control, alarms often work in tandem with door closers. Learn more in our guide on how to choose the right automatic door closer.
Most Frequent Alarm Problems and What They Mean
- Constant beeping: Usually indicates a low battery, tampering, or door left open.
- No alarm when door opens: The system may be disarmed, broken, or have a wiring/power failure.
- False alarms: Triggered by door movement, HVAC drafts, or sensor misalignment.
- Alarm won’t arm: Can happen due to worn keys, keypad errors, or drained batteries.
If your alarm also isn’t latching properly, review our guide on adjusting a panic bar that doesn’t latch.
Step-by-Step Troubleshooting Guide
- Check the door position. If ajar, the alarm may not reset.
- Verify the power source. Replace batteries or check the hardwired connection.
- Use the correct key or code to arm/disarm the unit.
- Inspect sensors or contacts for misalignment or dirt buildup.
- Test the alarm trigger by opening the door. Confirm if the unit sounds and resets properly.

When the Alarm Won’t Stop Beeping
If your alarm continues beeping after a door closes, it could be:
- A low battery warning
- A door sensor stuck in the open position
- An internal system error
Try resetting the unit by disarming and removing power. Then rearm after a few seconds. If that doesn’t work, the unit may need to be replaced.
What to Do if the Alarm Doesn’t Go Off
This is a serious issue and should be addressed immediately. First, test the unit with the power source verified. If the alarm doesn’t trigger, it could be:
- A failed contact switch
- Disconnected wiring
- A disabled system setting
Re-check all hardware connections or call a locksmith for same-day diagnosis and repair.
Low Battery and Power Issues
Most standalone units use a 9V battery or similar. Signs of battery failure include dim LED lights, weak sirens, or delayed responses.
Always replace with recommended batteries and mark your maintenance calendar. For hardwired systems, check the transformer and power input before assuming it's a fault in the unit.
False Alarms: Causes and Fixes
False triggers are often caused by:
- Vibration from nearby doors
- HVAC airflow disturbing the sensor
- Loose panic hardware or misaligned contacts
Ensure the strike plate aligns correctly, tighten all hardware, and relocate any airflow vents blowing directly on the exit door.
How to Reset Your Exit Alarm System
Most exit alarms can be reset in these steps:
- Turn the key or enter the code to disarm
- Close the door fully to allow the contact to reconnect
- Wait 10–30 seconds, then rearm the system
Some models have a hidden reset button under the cover plate. Refer to your manufacturer guide for specific reset procedures.
Maintenance Tips to Prevent Future Issues
- Test your alarm monthly using the manual override or test button
- Replace batteries every 6 to 12 months
- Check mounting screws and wiring annually
- Clean sensors with a dry cloth to remove dust or debris
- Log every service or inspection for insurance and fire code documentation
