Help when the product does not work
Connection type is not confirmed: check the model and manual before assuming it uses a battery. Record the current fault and visible changes; leave electrical troubleshooting to the installer.
Choose the symptom and check the model scope before following the steps. This is troubleshooting, not a list of confirmed product defects.
General advice — model-specific fault procedure missing.
Door/window sensor: shows open when closed
Applies to: General advice for the sensor type — not a verified procedure for this model. Use the model manual for opening, battery type, testing and settings.
- Check that the message concerns the correct door or window. Close it fully and read the current state again.
- If the sensor uses a magnet, look for loose, displaced or damaged parts. Correct side and distance depend on the model.
- Arrange an open/close test with the monitoring service. Compare the actual position with current system state, not just old events.
Check the result: The correct zone changes between open and closed.
Stop and get help: If the fault persists, let the installer check alignment and any external contact. Do not add a loose magnet or bridge wires.
