Common Types of Exit Door Alarms
Exit alarms vary depending on the building’s use and code requirements. Here are the most common types:
- Standalone alarms: Battery-operated units that sound when the door is opened without authorization. These are popular in retail and schools.
- Integrated systems: These tie into building security and fire systems. Often hardwired and networked for central monitoring.
- Delayed egress alarms: Allow exit only after a short delay (usually 15 seconds) and are paired with security measures.
- Exit alarms with magnetic locks: Combine alarm triggers with locking systems that disengage during fire emergencies.
Each has different troubleshooting requirements depending on installation and power source. Choosing the right setup is essential. Learn more about compliant hardware in our guide on why every business needs emergency exit hardware.
How Exit Door Alarms Work
Exit alarms are triggered when a door is opened without disarming the alarm first. Most are armed using a key switch, keypad, or automatic timer. The core components include:
- Door contact sensor or latch monitor
- Sounder (siren or buzzer)
- Battery backup or wired power source
- Control panel or internal circuitry
Some models integrate with automatic door closers and panic bars, while others stand alone. If the sensor loses contact or is misaligned, it can result in unwanted noise or failure to activate.
Most Frequent Alarm Problems and What They Mean
These are the most common issues we see with exit door alarms in Round Rock:
- Constant beeping: Usually a low battery warning or sensor error
- Alarm doesn’t activate when door opens: Misaligned sensor or disarmed state
- Random false alarms: Drafts, loose hardware, or faulty contact switches
- Alarm won’t reset: Lock cylinder or control board malfunction
- No sound at all: Dead battery, power loss, or fried sounder
If your panic hardware also seems out of sync, read our guide on adjusting panic bars that won’t latch properly.
Step-by-Step Troubleshooting Guide
- Check the battery status—if the alarm is beeping intermittently, replace the battery first.
- Inspect door alignment and make sure the contact switch is closing properly when the door shuts.
- Test the alarm by opening the door while armed. If it doesn’t trigger, check the sensor wires.
- Try arming/disarming the unit using the key switch. If the switch fails to turn, you may need a locksmith.
- Press the reset button or follow the manufacturer’s reset sequence.
If you’ve followed these steps and still experience issues, professional help may be needed to replace worn internal components.
When the Alarm Won’t Stop Beeping
This is one of the most common complaints. Typically, the cause is:
- Low battery warning
- Sensor not fully closed
- Reset switch stuck in mid-position
Try replacing the battery and firmly closing the door. If the beeping continues, there may be an issue with the door sensor alignment or a damaged control board.
What to Do if the Alarm Doesn’t Go Off
If your alarm fails to activate during a door opening, start with these checks:
- Is the system armed?
- Are the contact switches clean and properly aligned?
- Does the alarm have power?
Most failures are due to deactivation or misalignment. If it’s wired to a panel, confirm signal flow from the exit device to the alarm head. Consider pairing it with code-compliant exit alarm systems to ensure reliability.
Low Battery and Power Issues
Many exit alarms rely on 9V or lithium-ion batteries with a lifespan of 1–3 years. Indicators of low power include:
- Dim LED indicators
- Faint or irregular beeping
- Failure to activate or reset
Replace batteries as part of your building’s routine maintenance. For hardwired alarms, check fuse boxes and backup power connections.
False Alarms: Causes and Fixes
Nothing disrupts business more than an alarm going off for no reason. Common triggers include:
- Slamming doors causing brief contact separation
- Drafts or pressure changes moving the door slightly
- Loose panic bar mechanisms causing bounce-back
To fix this, tighten door hardware, recalibrate sensors, and ensure your panic hardware is properly adjusted. For more insight, review types of push hardware and how they integrate with alarms.
How to Reset Your Exit Alarm System
Resetting the alarm restores it to default armed mode. Here's how:
- Use the manufacturer key or combination if it has a mechanical switch.
- Press and hold the reset button for 5–10 seconds.
- If the alarm is tied to a building system, reset the control panel.
If the alarm still doesn’t reset, a faulty switch or internal damage may require replacement.
Maintenance Tips to Prevent Future Issues
Exit alarms are often neglected until they become a problem. To keep yours running smoothly:
- Replace batteries every 6–12 months or as needed
- Inspect and test the alarm weekly
- Clean contact points with non-corrosive electrical cleaner
- Check panic hardware for misalignment or sticking
- Document tests in a fire code compliance log
For alarms with integrated access control or delays, regular diagnostics are even more critical. Stay ahead of problems before they disrupt your business or safety plan.
