- 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 THE DOOR OR WINDOW THAT HAS THE LOW BATTERY
Locate the tab on the short side of the contact. Insert the flat head screwdriver into the tab using the screwdriver to gently press the tab, thereby removing the cover. If you do not have a tab but instead have a notch, insert the flat head screwdriver into the notch and gently twist to release the cover. Be careful not to force the device open.
ACCESS THE BATTERY(IES) Once the cover is released, remove the cover.
Please Note: The keypad may emit a beeping tone to indicate that the cover has been removed.
- INSTALL THE NEW BATTERY(IES)
Remove the existing battery(ies) and install the replacement battery(ies), paying attention to the polarity. (Ensure that the positive (+) end of the battery matches the positive (+) symbol inside the contact.) Reconnect the cover on the contact by re-attaching it. The cover should click into place once it is issued.
- 4. TEST THE CONTACT
After replacing the battery(ies), Guardian recommends testing the contact to ensure it is working properly. Arm your system and trigger an alarm at the door or window where the contact is installed. Allow the system to sound for at least 30-45 seconds before entering your disarm sequence. Confirm the test signal was received before having your system removed from Test Mode. Visit Customer Care Website or contact Guardian's Customer Service Department at 1-888-895-4805 to have your system removed from Test Mode.
