Help CenterThe GEO-CT door/window sensor requires a CR2032 battery. Once the battery is low, the GEO-CP panel displays a low battery icon next to the sensor in the devices list. The battery must be replaced within 7 days of the first low battery notification. If the battery is not replaced within 7 days, the sensor may not function properly.
To Replace the Battery:
- Locate the bottom of the sensor (the slotted short end). 2. Gently slide a fingernail/fingertip into the slot and pull the sensor cover out and away from the sensor's base. 3. The sensor containing the battery and circuit board is no longer attached to the door/window. Locate the tab holding the circuit board in the sensor. 4. Press and hold the tab away from the circuit board, and then turn the sensor over. The circuit board comes free from the sensor shell. 5. Use a fingernail/fingertip to push the battery out of the casing, noting the polarity of the battery. 6. Slide a new CR2032 battery into the battery casing, making sure that the polarity is correct. 7. Press the circuit board back into the sensor casing until secure. There will be an audible snap. 8. Press the sensor back onto the base. 9. Test the sensor. Warning: If an incompatible replacement battery is used, or the battery is installed incorrectly explosion or damages may occur.
