  1. PLACE YOUR SYSTEM ON TEST
    Before changing the battery, ensure the system is disarmed and go to Guardian's Customer Care Website. You may also contact our Customer Service Department at 1-888-895-4805 to have your system placed on test. This ensures Guardian doesn't accidentally notify the authorities.

  2. LOCATE THE BATTERY
    Locate the Glass Break Sensor that has the low battery.

  3. REPLACE THE BATTERY
    Remove the existing batteries and install the replacement batteries paying attention to polarity. Ensure positive (+) end of the battery matches the positive (+) symbol. Once the batteries are installed, reattach the front cover by clicking it back into place.

    Depending on the model of the sensor, you may need to open your sensor differently, but in most instances you will need to gently pull the cover straight off the mounting bracket. Some covers are secured with a screw which would need to be removed before trying to detach the cover. Other sensors may require you to insert a flathead screwdriver into the notch at the top or bottom of the sensor and gently twist it to release the cover.

  4. REPLACE THE BATTERY

Dispose of the old battery properly. Some areas may offer a battery recycling center.
