Common Types of Exit Door Alarms
There are several kinds of exit alarms used in commercial settings:
- Standalone Exit Alarms: Mounted directly to panic bars or exit doors; battery-powered with internal buzzer.
- Integrated Access Control Alarms: Tied into electronic locking systems, often hardwired to fire panels or access controls.
- Delayed Egress Alarms: Add a short delay (typically 15 seconds) before unlocking, while sounding a warning tone.
Choosing the right type depends on occupancy load, door type, and compliance needs. For panic bar integration help, visit our page on fixing panic bars that don’t latch.
How Exit Door Alarms Work
Most alarms are activated when someone pushes the bar or opens the door without disarming the system. They emit a loud sound (85-120 dB) to alert staff and deter misuse. In many cases, they also trigger notification systems tied to fire or security networks.
Some include key switches or magnetic door contacts that reset the alarm once the door is closed. Others reset automatically after a set time or require manual input.
Most Frequent Alarm Problems and What They Mean
Common issues with exit alarms include:
- Constant Beeping: Often caused by low batteries, sensor misalignment, or tampering attempts.
- No Sound When Door Opens: May indicate a wiring failure, dead battery, or faulty sensor.
- Alarm Sounds Without Door Opening: Likely caused by vibration sensitivity, sensor failure, or door warping.
Each of these signs requires prompt attention to keep your exits both secure and compliant.
Step-by-Step Troubleshooting Guide
- First, inspect the alarm’s LED indicator—most units blink codes for battery or sensor errors.
- Open the device housing (using the key or security bit) and check the battery. Replace if it’s low or expired.
- Examine the door contact switch and magnet. Clean any dirt and ensure they align properly when the door is closed.
- Press the reset button or turn the reset key. If it doesn’t silence the alarm, disconnect power and reconnect after 10 seconds.
- Still not working? You may need to replace the internal circuit board or consult a technician.
When the Alarm Won’t Stop Beeping
Persistent beeping is often a low battery alert. Replace the battery first—typically a 9V or AA set. If that fails, inspect for stuck sensors or loose internal wiring. Beeping can also signal tamper attempts.
If your alarm is connected to a fire panel or integrated access system, check those connections as well.
What to Do if the Alarm Doesn’t Go Off
If the door opens and no alarm sounds, check that the alarm is powered. Then inspect the magnetic contact and ensure it’s mounted correctly. If battery-powered, ensure fresh batteries are installed and the contact wires are secure.

Low Battery and Power Issues
Low battery is the #1 cause of exit alarm problems. Most units will beep periodically to indicate a dying battery. Replace batteries at least once a year, or more frequently in high-use areas.
If your alarm is hardwired and still losing power, inspect the transformer or breaker and consult your building's electrician.
False Alarms: Causes and Fixes
False alarms are frustrating and often triggered by:
- Door slamming or vibration
- Misaligned or dirty magnetic contacts
- Humidity or temperature swings causing sensor drift
- Electrical surges affecting integrated systems
Make sure all hardware is tight, weather-sealed, and installed per manufacturer specs. Alarms mounted on hollow-core doors are more prone to false alerts.
How to Reset Your Exit Alarm System
Most exit alarms reset using a key switch. Insert the key, turn to the “Reset” position, and hold for 3-5 seconds. Some models have a push-button instead.
If the alarm is wired into a security panel, resetting it may require code entry or software access. Refer to your model’s manual or consult a locksmith for multi-system setups.
Maintenance Tips to Prevent Future Issues
Regular maintenance extends the life of your exit alarm and ensures reliable performance. Best practices include:
- Test the alarm function weekly
- Replace batteries annually or as needed
- Clean and realign magnetic contacts monthly
- Inspect housing for tamper attempts or moisture
- Schedule annual service checks with a locksmith
Proper care reduces false alarms, prevents failures during emergencies, and helps pass inspections.
