Micro Door and Window sensors are use modern sensor technology that is compact and designed to protect almost anything that opens—doors, windows, jewelry cases, gun cabinets, safes, and more. They provide total home security and are crucial to the protection of your home. If you are having problems with your sensors, here’s a quick troubleshooting guide to help you get them back online again.

Low Battery

If your sensors are low on battery, the central panel will report the condition.

Protect America’s Lifetime Warranty does not cover any batteries. There are many options for your to acquire a replacement battery. We recommend obtaining them from a third party vendor, since that will likely be the fastest and most efficient source. However, if you are unable to find one at a local store, it is possible to order one from Protect America. The battery you will need is CR2032. Once you have the battery in your possession, here are the steps to changing it out:

Micro-Battery1

  1. Take your sensor (the larger part, not the smaller magnet) and open it by prying the sides of the sensor and giving a slight lift.
  2. Once the device is open, slide the battery out and replace it with the new battery. Make sure to dispose of the old battery properly and promptly (so it doesn’t get mixed in with new batteries).
  3. Assemble the device again, and test it to ensure that it’s working properly.

Sensor open

If your sensor is reporting that it is open, even when you can see that they are closed, the sensor might have been disturbed or not reset properly. Here are some steps you can take to fix this problem.

Micro-Open1

  1. Verify that the sensor and the magnet are both set up correctly. Consult the diagram above for reference.
  2. If it is not set up correctly, separate the sensor and the magnet.
    1. Realign them and ensure that they are 3/8ths of an inch apart.
    2. If you can fit more than a pencil between the sensor and the magnet, it’s too far apart and may cause it to think that the sensor door is open.
  3. Check what type of door you are using.
    1. Doors made of steel may disrupt the magnetic field between the sensor and the magnet.
    2. Take the sensor off the steel door and try it on a wooden frame to see if you’re still having the same problem.
    3. If it works on the wooden frame, then the sensor is fine, and the metal door is disrupting the system.
    4. When putting it back on the steel door, use a Spacer to create a barrier.
    5. If you cannot find the Spacers from your original package, give us a call.
  4. Reprogram the sensor in the panel to refresh the signal.
    1. If you have a Simon 3 panel:
      1. Remove the sensor: open the cover, type 1960, press delete, press sensor/remote until the desired sensor, and then press done.
      2. Add the sensor again: open the cover, type 1960, press Add, press Sensor/Remote, trip the device, press Sensor/Remote until Sensor Name is announced, press Done, use the red numbered keys to enter the group number, press Done.
    2. If you have a Simon XT Panel:
      1. Remove the sensor: Scroll to System Programming, press OK, type 1960, press OK, scroll to Sensors, press OK, scroll to Delete Sensor, press OK, scroll to desired sensor, and press OK.
      2. Add the sensor again: scroll to System Programming, Press OK, type 1960, press OK, scroll to Sensors, press OK, scroll to Learn Sensor, press OK, trip the device, use the keypad to change Sensor Group, and press OK.
  5. After all going through all of these troubleshooting steps, if the sensor is still not working, then it needs to be replaced through our Lifetime Warranty. Call us today at 1-800-951-5111 to get your sensor replaced right away.

Sensor Failure

When your Panel cannot communicate with the sensors, the Panel will make Trouble Beep sounds, and the status button will light up. Here are the steps you should take to try and figure out what is wrong:

  1. Press the STATUS button on the panel to determine which sensors are causing the error.
  2. Perform an environmental check: Is the internet router too close to the control panel? Is the internet router too close to the sensors? Are there any AC/power lines behind the system panel? Is there a cordless phone too close to the system panel? If so, relocate the necessary equipment to avoid communication issues. If you have questions or need help deciding how to relocate them, call us at 1-800-951-5111.
  3. Make sure  that the sensor is within 100 feet of the control panel. It may be necessary to move the control panel to a centrally located area of the home or move the sensor closer to the control panel.
  4. The control panel’s antenna sit vertically, so it’s best for your sensor to be vertical as well.
  5. Check what type of door you are using.
    1. Doors made of steel may disrupt the magnetic field between the sensor and the magnet.
    2. Take the sensor off the steel door and try it on a wooden frame to see if you’re still having the same problem.
    3. If it works on the wooden frame, then the sensor is fine, and the metal door is disrupting the system.
    4. When putting it back on the steel door, use a Spacer to create a barrier.
    5. If you cannot find the Spacers from your original package, give us a call.
  6. Perform a sensor test
    1. If you have a Simon 3 Panel, open the panel, enter 1960, press the Test Button from the Main Menu, press DONE to activate the sensor test.
    2. If you have a Simon XT, scroll to System Test, press OK, enter 1960, press OK, scroll to Sensor Test, press OK, and the panel should announce the sensors programmed into the system panel.
  7. If you have gone through all of these troubleshooting steps, and the sensor is still failing, you may need to get it replaced through our Lifetime Warranty. If the sensor is malfunctioning, you will need to delete it from your panel and system. If a malfunctioning sensor is kept on the system, it may result in false alarms.
