Common Types of Exit Door Alarms
Exit door alarms come in a few common configurations. Surface-mounted alarms are battery-powered and install directly onto the door or frame. These are ideal for retrofit projects or temporary installs. Hardwired alarms connect to your building’s fire or access control system for added functionality and monitoring.
Other variations include delayed egress alarms (which hold the door locked for a few seconds before opening), push-bar integrated alarms, and motion-triggered sensors. Many businesses in Pasadena use a mix depending on their floor plan and door types. Learn more about which types meet your code needs in our article on fire code-compliant exit alarms.
How Exit Door Alarms Work
Most exit alarms work by monitoring the door position. When the door is opened without the alarm being disarmed (via key, keypad, or fob), it triggers a loud siren. Some models also flash lights or send alerts to security systems.
The alarm is typically armed automatically once the door is shut. If the battery is low, wiring is faulty, or the door fails to latch, the system may not work as expected. This is why regular maintenance and inspection are critical.
Most Frequent Alarm Problems and What They Mean
- Constant Beeping: Usually means a low battery or door that didn’t latch fully.
- No Sound When Door Opens: Could be a dead battery, faulty wiring, or disarmed state.
- Alarm Goes Off Randomly: Caused by door misalignment or sensor errors.
- Alarm Resets on Its Own: Could be due to wiring issues or a failing internal circuit.
If you hear chirping or intermittent beeps, it usually means the system is trying to alert you to something minor like battery voltage or a tamper attempt.
Step-by-Step Troubleshooting Guide
- Check the door for proper latching—make sure it closes and clicks securely.
- Inspect the battery status indicator—replace batteries if needed.
- Examine any wiring or connectors for loose or corroded terminals.
- Try disarming and rearming the system using the key or access control.
- Reset the unit if it has a manual reset button.
If the problem persists after these steps, you may be dealing with internal damage or misconfigured settings. Don’t attempt disassembly unless you're trained—see our repair guide for related hardware issues.
When the Alarm Won’t Stop Beeping
Persistent beeping is often a low battery warning. Replace the batteries using the manufacturer’s recommended type and check the terminals for corrosion. If you’re still hearing beeps after replacement, try a full reset.
Other possible issues include a stuck tamper switch or misaligned door magnet. Gently clean and realign the contacts if needed.
What to Do if the Alarm Doesn’t Go Off
If the door opens and nothing happens, first check the battery and power connections. Next, test the door’s alignment. The contact sensor may not be detecting the door in the closed position, causing the system to think it’s disarmed.
Also make sure the device isn’t disarmed with a bypass key left in the cylinder. Some alarms also time out after long disuse and may need to be cycled on and off.
Low Battery and Power Issues
Low battery is the most common cause of exit alarm trouble. Most models beep or chirp periodically when battery voltage drops. Change batteries at least once a year or more often in high-use areas.
If you're using a hardwired model, check the building’s power source, backup battery pack, and fuse status. Intermittent power can cause glitches and false alarms.
False Alarms: Causes and Fixes
False alarms are annoying and can cost your business time and money. These often happen when the door doesn’t latch, causing the alarm to assume it’s being opened. Weather changes can warp doors and affect alignment.
Clean door contacts, tighten loose screws, and inspect sensors. If alarms are triggered by vibration or minor movement, consider upgrading to a more stable model. You can find reliable options at trusted commercial door hardware suppliers.
How to Reset Your Exit Alarm System
Most exit alarms can be reset using a key switch, access control device, or internal button. Hold the reset switch for 5 seconds or until the beep stops. For battery-powered models, some require opening the unit and pressing a recessed reset pin.
Always reset the alarm after servicing or changing batteries to ensure it arms properly.
Maintenance Tips to Prevent Future Issues
Routine checks can help avoid emergency repairs. Test your alarm monthly by opening the door and verifying the sound. Check battery levels, clean sensors, and inspect mounting hardware for loosening over time.
Lubricate latches as needed and pair the alarm with a properly adjusted closer. See our post on selecting the right door closer to ensure smooth closure and secure latching that won’t falsely trigger alarms.
