If your door or window sensor isn’t working as expected, don’t worry — we’ll walk you through some quick and easy steps to get it back on track.

Step 1: Check the Magnet Alignment

• Make sure the magnet and sensor are lined up correctly, with a gap of less than 1 inch.
  • If everything looks good but the sensor still isn’t responding, move on to the next step.

Step 2: Reconnect the Sensor

1. Remove the sensor from your control panel.
2. Re-add the sensor to the panel.
3. Test it again — this often solves the issue!

Step 3: Check for Metal Interference

Is the sensor installed on a metal door or window? Metal can sometimes interfere with signal communication. Here’s how to test it:

1. Remove the magnet from the metal surface.
2. Gently separate the sensor and magnet to simulate opening/closing.
3. Watch your panel — if it shows the correct “open” or “closed” status, the sensor is working!
4. Try reinstalling the sensor on a non-metal surface for better performance.

Step 4: Replace the Battery

Still not working? Try a fresh battery in the sensor.
Then, repeat the open/close test. If it starts responding again, the battery was the issue!
