Commons Door Alarm Sensor Problems and Solutions

If you are facing a problem with your alarm door sensor, first of all, you need to find the reason to fix it. Below are 4 common problems with door alarm sensors, including the causes and solutions that can help you.

Problem #1: False alarms

False alarms refer to instances where an alarm system or warning mechanism is triggered without the presence of an actual threat or emergency. Such occurrences can lead to unnecessary panic, wasted resources, and decreased trust in alarm systems. 

According to Northeast Security Solutions, one of the most common causes of false alarms is when the gap between the contact and magnet of the door sensor increases due to weather-related wear and tear, causing the magnet to no longer “sense” a connection. Other causes of false alarms include motion detectors placed too near a heating or cooling vent, loose doors or windows, and incorrectly placed motion sensors.

To fix a door sensor,  you can check the cause and implement some solutions such as:

  • Clean your device and make sure the sensor and magnet are aligned and that they haven’t been altered.
  • Verify that the spacing between the sensor and magnet is no further than 1″ when the door/window is closed.
  • Replace Batteries 
  • If the batteries have already been replaced, replace the sensor.

Another cause of a malfunctioning wireless door sensor is that it may be out of range of the panel. In addition, there are some other causes such as: Loose wiring, damaged sensors, interference from other electronic devices.

Some solutions you can do to fix this problem:

  • Check the batteries and replace them if necessary.
  • Make sure the wiring is secure and that there are no loose connections.
  • Test the sensor in a different location to see if it is working. If it is, the problem may be with the original installation location.
  • Move the sensor away from other electronic devices, such as microwaves, cordless phones, and routers.

The thieves can easily sneak into the house if the smart door lock does not issue a warning

Problem #3: Malfunctioning indicator

The door alarm sensor does not show the correct status of the door, such as open or closed. It could be due to a faulty contact, a gap that is too large between the two contacts, loose wires, or a damaged cable. Here are some recommended troubleshooting steps to take:

  • Check for any metal doors, windows, or frames that may be interfering with the sensor’s signal.
  • Check the status of the sensor light to see if it is functioning properly .
  • Check the alarm settings to ensure that the sensor is properly configured.
  • Check the placement of the sensor to ensure that it is properly aligned with the magnet.

You should also check the compatibility and configuration of the sensor and the smart door lock. The sensor and the smart door lock (khóa cửa điện tử thông minh) should be compatible and configured with each other. If they are not, the sensor may not recognize the lock status and show the wrong status.
