How to replace the battery in a 2GIG Recessed Door/Window Sensor
Locate the sensor that has a low battery by verifying the zone number and location of that sensor on the alarm panel.
Place the alarm panel in walk test mode.
Go to the sensor on the door.
Locate the lid of the sensor.
Using a flatblade screwdriver, open the sensor by prying it off using the screwdriver. Once it comes loose, remove it from the sensor.
Pull the sensor out using sharp nose pliers if you cannot reach it.
With the sensor removed, you can now see the battery that needs to be replaced. (Battery has been removed in below photo)
Remove the old battery from the sensor, by pulling it straight up out of the battery tray.
Now that the battery has been removed from the sensor, replace it with a new CR2 battery.
Pay close attention to the orientation of the battery in the battery tray. The battery will have a positive side, and a negative side, and the battery tray will have the proper orientation marked.
Once the battery has been replaced, you will need to replace the sensor inside the housing. Push the sensor back into the housing making sure it is installed in the same direction it was installed to start.
Install the lid of the sensor back in place making sure that the tabs line up properly, then secure it by using your finger to press the lid in securing it in place.
Now that the lid of the sensor is properly secured onto the sensor, we will want to reboot the panel.
Now that the panel has been rebooted, test the sensor by opening the sensor that was affected. If no Low Battery returns, the sensor has been fixed. If the Low Battery returns, the sensor may need to be replaced, at this point contact our Technical Support department.
If your Door/Window sensor is causing false alarms while the alarm system is armed it is usually caused by the magnet being too far away from the sensor. This is an issue because the magnet needs to be within range of the sensor for it to read properly. Sometimes it can be just far enough that it will work most of the time, but occasionally cause false alarms. In order to fix this, remove the magnet from the sensor from where it is installed, and reinstall it closer to the sensor. If you do not know how to do this, contact our Technical Support department for assistance.
Occasionally false alarms can be caused by the wind blowing on the door or window causing it to wiggle, and that can set the alarm off. If this is the case, most of the time, moving the magnet closer to the sensor will fix the issue, but in some cases the sensor and magnet combo may need to be moved to another location on the door or window that moves less. If the sensor and magnet are properly installed, and the door or window do not get moved by wind, contact Technical Support for assistance.
2GIG Recessed Door/Window Sensor not showing closed
If the Recessed Door/Window Sensor is saying that it is open on the panel, it is most likely that the sensor and the magnet are too far apart. Make sure that the gap between the magnet in the door, and the sensor in the jomb is less that ¼ of an inch. If this gap is larger than that, it may not function properly. If the gap is ok, and the sensor still is not working properly, contact our Technical Support department.
Loss of supervision on 2GIG Recessed Door/Window Sensor
If a Recessed Door/Window Sensor is showing a loss of supervision, this means that for whatever reason, the sensor is not being monitored by the alarm panel. To ensure that the sensor is being monitored properly perform the following troubleshooting steps.
Perform a walk test on the sensor.
If this sensor has a history of low battery, the battery may have died completely, and is no longer being monitored as it no longer has power. If this is the case, replace the battery in the sensor. If you do not know how to do this, view the article titled "How to replace the battery in a 2GIG Recessed Door/Window Sensor".
Ensure that the sensor is within range of the panel. It needs to be within 150 feet of the panel, with minimal interference, (walls, doors, etc.) If the signal strength is the issue, more equipment will need to be installed. Contact our Technical Support department for assistance.
If none of these reasons explain the loss of supervision of the sensor, you will need to contact our Technical Support department for assistance.
