Do you need a battery?
Make sure you have batteries before you proceed. Visit your nearest retail store that sells batteries or click the button below to order your replacement battery kit.
Call us at 1-800-xfinity if you receive a low battery alert within 30 days of device installation.
How to install the battery
Before proceeding, make sure that your system is disarmed. Working on devices while the system is armed can generate false alarms.
Did You Know? If you need to remove your Sensor from the wall to install a battery, you may want to have some double-sided tape on hand. Use the tape to reattach your Sensor if its existing adhesive fails to hold it in place.
Help Protect Our Environment: Please properly recycle your discarded batteries, which are conveniently accepted at various locations. To find a recycling location near you, check www.call2recycle.org or call 1-800-8-Battery (1-800-822-8837).
Is This Your Sensor? Make sure that your Sensor looks like the one in the image below. If it does, you're in the right place to find out how to install a battery in your Sensor.
- Place your thumb or finger on the top edge of the sensor cover and push/pull towards the end of the Sensor. The cover will slide a short distance and stop; you can then pull the cover off of the Sensor. After removing the cover, you may receive a tamper alert from your system. The tamper alert warns you when the cover of your device is open and will clear once the battery is replaced and the cover is reattached.
Take a Look: If a battery is already present, remove it by gently using your fingertip to pull one end of the battery up until the battery is loose; you can then pull it free from the slot.
Important: If you're replacing the battery in response to a low battery alert, wait five minutes between removing the current battery and inserting the new battery. The alert will not clear if the battery is replaced more quickly. - Insert the CR2450 battery by placing it flat against the prongs in the battery compartment with the negative (-) side facing down. The battery should fit inside the battery cradle.
Be sure not to press down on the tamper (red square) when inserting the battery as this will reset the Sensor to the factory settings. - Align the small tab on the cover with the slot in the track on the Sensor body. Press the cover down onto the Sensor.
- Use your thumb or finger to slide the cover towards the opposite end of the Sensor until it snaps into place.
- When the battery is inserted correctly and the cover is reattached, the green light on the front of the Sensor illuminates.
- If you're replacing the battery, confirm that the low battery alert has resolved and the Sensor appears on your list of connected devices in your touchscreen or the Xfinity Home app.
- Test the Sensor to confirm that it is working correctly.
