Common Types of Exit Door Alarms
There are several types of exit door alarms commonly installed in commercial buildings:
- Surface-Mounted Alarm Devices: Installed directly on the door, often combined with a panic bar or crash bar.
- Delayed Egress Alarms: Sound an alert but delay door unlocking for 15 seconds, often used in retail settings.
- Integrated Exit Devices: Panic bars with built-in alarms for fire-rated doors.
- Standalone Battery-Powered Alarms: Cost-effective option with limited functionality.

How Exit Door Alarms Work
Exit alarms are typically activated when the door is opened without authorization. They’re powered by batteries or a wired power source and often integrate with a magnetic contact, panic bar, or electric strike.
Some alarms connect to your security system or access control panel. Others are standalone, sounding only a local alarm to alert staff. For a closer look at hardware compatibility, visit how to find the right door closer.
Most Frequent Alarm Problems and What They Mean
- Constant beeping: Often caused by a low battery or loose door contact.
- No sound when the door opens: May indicate a bad sensor or disconnected power source.
- False alarms: Can be triggered by a misaligned sensor or failing strike plate.
- Failure to reset: Usually an internal software or mechanical issue.
Don’t ignore recurring issues—they can result in compliance violations and system failure during an actual emergency.
Step-by-Step Troubleshooting Guide
- Inspect the power source—check for battery life or electrical connection.
- Look for visible damage or corrosion around the sensor contacts.
- Test the door by opening and closing it slowly to see when the alarm engages.
- Try resetting the device using the key or internal button (if available).
- If none of these steps fix the issue, contact a commercial locksmith.
Still stuck? Your issue may be with the panic bar itself. See how to adjust a panic bar that doesn’t latch.
When the Alarm Won’t Stop Beeping
A beeping exit alarm usually indicates a low battery, tampering, or door misalignment. First, replace the battery if it's a standalone model. Then, check the door’s position and ensure it’s fully closed and latched.
If your alarm is tied to an electronic system, you may need to reset the circuit or check the access control configuration.
What to Do if the Alarm Doesn’t Go Off
Start by testing the sensor or magnetic contact. If the magnet and sensor are too far apart, the alarm may not trigger. Reposition or replace the magnetic contacts if needed.
Check wiring or internal fuses on hardwired models. If everything checks out and the device is still silent, replacement may be required.
Low Battery and Power Issues
Many exit alarms use 9V or AA batteries that should be replaced every 6–12 months. Some models flash a warning light or emit a faint beep when battery power is low.
Hardwired units may be affected by power surges, outages, or damaged transformers. Make sure backup power is tested regularly to avoid total system failure.
False Alarms: Causes and Fixes
Common causes of false alarms include:
- Misaligned sensors
- Loose doors or faulty latches
- Mechanical wear on panic bars
- Environmental factors like strong wind or slamming doors
Try repositioning the magnetic contact or upgrading to a more secure panic bar. Learn about options in fire-rated panic hardware.
How to Reset Your Exit Alarm System
Each model has a different reset procedure. Some require a key; others include a reset button inside the housing. Start by silencing the alarm, then re-close and latch the door. Use your key or code to reset the system and ensure proper contact alignment.
If the reset doesn’t work, try replacing the batteries or checking the system wiring.
Maintenance Tips to Prevent Future Issues
Regular exit alarm maintenance includes:
- Testing the alarm monthly
- Replacing batteries twice a year
- Cleaning contact points and checking for corrosion
- Verifying latch and door closer operation
Routine checks ensure your building stays secure and compliant. Need a refresher? Read our guide to exit alarm compliance.
