Common Types of Exit Door Alarms
There are several types of exit door alarms commonly found in commercial buildings. The most popular are standalone battery-powered alarms that sound when the door opens. Others are hardwired into a fire or security system. Some models include a delayed egress feature, allowing a few seconds to disarm before sounding.
Integrated panic bars with built-in alarms are popular in retail and healthcare facilities. These combine physical egress with sound alerts. For specialized environments, you may also see electromagnetic locks paired with audible alerts and key bypass systems.

How Exit Door Alarms Work
Exit alarms are triggered by a door opening without authorization. They usually include a switch or sensor that breaks contact when the door moves. The system then triggers a siren or beeping tone. Some alarms are silent and instead send a signal to a central monitoring station.
Most alarms can be armed or disarmed with a key, code, or electronic access system. Batteries or wired power ensure they remain active 24/7 unless purposefully disengaged.
Most Frequent Alarm Problems and What They Mean
Here are some common issues:
- Constant beeping: Often indicates a low battery or sensor misalignment.
- No alarm when door opens: May be due to dead batteries, a faulty switch, or disarmed status.
- False alarms: Could be caused by a loose door, wind drafts, or electrical noise.
- Alarm resets randomly: Possibly due to power surges or internal damage.
Many of these problems can be prevented with regular testing and upkeep.
Step-by-Step Troubleshooting Guide
1. Inspect the power source: Check battery life or circuit breaker if hardwired.
2. Test the door contact: Slowly open and close the door while listening for clicks or alarm changes.
3. Check for physical damage: Loose wiring, dirty contacts, or cracked housings can cause failure.
4. Verify the alarm is armed: Use the key or code to check if the system is active.
5. Perform a reset: Power down the unit, wait 10 seconds, and reactivate it.
Always consult the manual for your specific model or contact a locksmith if unsure. For additional support, check out Exit Door Alarms for Fire Code Compliance.
When the Alarm Won’t Stop Beeping
This usually signals a low battery, tamper detection, or an open circuit. Replace batteries if possible. Ensure the door is closed tightly and that all sensors are aligned properly.
If the alarm continues even after inspection, you may need to reset the system. Some models also have internal timers that need to expire before disarming fully.
What to Do if the Alarm Doesn’t Go Off
If your alarm fails to sound, check whether it was left disarmed. Verify power supply and test sensors with the door slightly ajar. Battery-powered units may need a fresh battery or contact cleaning.
Also ensure the speaker or sound mechanism hasn’t been disconnected or vandalized. Malfunctioning alarms are both a safety and legal risk — don't ignore them.
Low Battery and Power Issues
Many alarms emit short beeps every minute when the battery is low. Always replace batteries with recommended types — typically 9V or AA, depending on the unit. Avoid mixing old and new batteries.
If hardwired, check the power connection and confirm the breaker hasn’t tripped. Surge protectors can also prevent failures during storms or outages.
False Alarms: Causes and Fixes
False alarms are frustrating and disruptive. They may be caused by loose door hardware, air pressure changes, or old batteries. Sometimes wiring issues or nearby electronics interfere with sensor signals.
Clean sensors regularly and tighten hardware. Make sure the alarm’s internal timer and delay settings match your needs. For other building code concerns, see Why Every Business Should Have Emergency Exit Hardware.
How to Reset Your Exit Alarm System
To reset most standalone alarms, insert the key into the arming cylinder, turn to "reset" or "off", wait 5 seconds, then return it to "armed". Some units have a button you can press with a paperclip or pen tip.
For integrated or digital systems, check the manual for reset sequences. Always re-test after resetting to make sure the alarm reactivates properly.
Maintenance Tips to Prevent Future Issues
Routine maintenance helps you avoid surprise failures. Here are some best practices:
- Check batteries every 6 months
- Clean contacts and alarm housing quarterly
- Test alarm functionality monthly
- Tighten all hardware and hinges
- Verify system is armed before closing business for the day
Also review any fire code updates and ensure hardware remains compliant. For sourcing quality hardware, visit Where to Buy Commercial Door Hardware in Houston TX.
