- 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.
- LOCATE YOUR PANEL BOX
Locate your all-in-one control panel and use a Phillips head screwdriver to remove the locking screw at the top of the panel.
ACCESS YOUR BATTERY Insert the flat head screwdriver into the slots at the top of the panel. There is one slot on the left and one slot on the right. You may need to gently twist the screwdriver to help separate the cover. Be careful not to force the panel open.
- DISCONNECT THE BATTERY
Now that the panel is open, follow the wires from the battery pack to the connector and unplug it from the panel. Remove the screws that secure the battery retainer (required Phillips head screwdriver) and remove the battery retainer, then remove the battery pack.
- CONNECT NEW BATTERY
**NOTE: Your security system may sound or the keypad may beep as an indication that the battery has been removed from the system. You may need to disarm the system after opening the panel to silence the tamper beeping tone
Insert the new battery and plug it into the panel. Be sure to feed the battery wires through the three routing clips. Depending on the size of the replacement battery, it will connect to either the two- or three- position connector.
Once the new battery is in place, reconnect the battery retainer. Carefully swing the panel up to the mounting plate and lock it into place.
