1. False Alarms

Nothing is more frustrating than a false alarm waking you, or worse, prompting a visit from local law enforcement.

- Update your system software if supported.
- Contact Matson Alarm for a system checkup if the problem persists.
2. Beeping Keypad or Trouble Beeps
The Problem:
An alarm keypad that beeps nonstop can be both annoying and confusing.
Common Causes:
- Low backup battery
- Communication failure with the central monitoring station
- Sensor tampering or damage
- AC power failure
How to Fix It:
- Replace the system battery (usually inside the control panel).
- Ensure your internet or phone line is working properly.

3. Faulty or Non-Responsive Sensors
The Problem:
A door sensor isn’t triggering the alarm, or worse, it keeps showing as “open” even when closed.
Common Causes:
- Misaligned magnets and sensors
- Dead batteries in wireless sensors
- Physical damage or dirt buildup
- Interference from metal or wireless devices
How to Fix It:
- Realign the magnet and sensor until the system recognizes a closed state.
- Replace batteries (most sensors use small lithium coin cells).
- Gently clean sensors with a soft cloth.
- Avoid placing sensors near large metal objects or routers.
If you’re using outdated equipment, upgrading through Matson Alarm may be the best long-term fix.
4. Communication Failure

Your alarm isn’t connecting to the monitoring center, leaving you unprotected in emergencies.

- Incorrect system programming
- Account or subscription issues
How to Fix It:
- Restart your modem or router.
- Check for service outages with your provider.
- Verify account credentials with your alarm provider.
- If you’re using a landline-based system, consider upgrading to a cellular module through Matson Alarm for better reliability.

5. Power Outages and Battery Failure
The Problem:
Your system shuts down during a storm or loses power unexpectedly.
Common Causes:
- Expired backup battery
- Unstable AC power source
- Poor wiring or installation
How to Fix It:
- Replace the backup battery every 3–5 years (or sooner if you receive warning beeps).

Pro tip: Schedule a yearly inspection with Matson Alarm to ensure your system is storm-ready.
