• How do I reset my Merrytek motion sensor?

  To reset the sensor, press the 'Reset' button on the compatible remote control. This reverts all parameters (detection area, hold time, daylight sensor, etc.) to the physical DIP switch settings on the unit.

• Why does the light stay on permanently?

  Permanent illumination can occur if there is continuous movement in the detection area or if the sensor is installed too close to reflective surfaces like metal, glass, or concrete walls, which may cause false triggering.

• What does the 'Test (2s)' button do?

  The 'Test (2s)' button puts the sensor into a factory test mode. In this mode, detection sensitivity is set to 100%, and the hold time is reduced to 2 seconds to allow for quick verification of sensor function. Pressing 'Reset' or any other button exits this mode.

• Can Merrytek microwave sensors detect motion through walls?

  Yes, microwave sensors can detect motion through non-metallic materials such as thin walls, glass, and plastic. However, metal surfaces will reflect the signal and block detection.
