8 Maintenance Tips for ADT Motion Sensor

  1. Check the motion sensor’s power light. A solid green light indicates that the device is receiving power. If the light is red or blinking, you may need to replace its battery. The power light can also alert you when it’s time to clean the lens or check for obstructions.
  2. Change the battery regularly. The ADT Motion Sensor should be powered by a 9-volt battery and it’s important to replace the battery as soon as it starts to fail in order to keep your system working correctly. If the power light turns red or starts blinking, replace the battery immediately.
  3. Keep the motion sensor lens clean and free of debris. Vacuum the area around the lens periodically and use a soft cloth to wipe away any dust build-up on the parts that don’t need to be covered with tape. This will help keep your motion sensor functioning properly.
  4. Check for obstructions or misalignment. Make sure that the motion sensor is mounted in an area where it won’t be blocked by furniture, curtains, plants, etc. If the lens of the Adt Motion Sensor is not aligned correctly, it will provide false alarms or fail to detect an intruder altogether.
  5. Test the motion sensor system on a regular basis. This will ensure that all components are functioning properly and that you are properly protected if an intruder does enter your home or business premises.
  6. Replace damaged parts immediately. If any of the wiring, batteries, or other parts of the Adt Motion Sensor become damaged, replace them immediately to ensure the continued security of your premises.
  7. Make sure the wireless signal is strong and secure. The ADT Motion Sensor uses a wireless connection to communicate with other devices in your home or business network. This should be checked regularly to make sure it’s transmitting properly and securely.
  8. Add additional motion sensors for increased coverage. Adding additional motion sensors to your Adt Motion Sensor system will increase the range and accuracy of detection, giving you better protection from intruders.
Add Additional Motion Sensors

These 8 maintenance tips will help ensure your Adt Motion Sensor is running optimally so that it can help protect your home or business premises with maximum efficiency.
