Having a replacement battery on hand is never a bad idea for the home owner who is always trying to be one step ahead of a burglar and natural disaster. Wireless alarm batteries, brand new, will last from about 3-5 years. Here is a step-by-step instructions to help you replace your battery, when the time comes.

1. Call State Alarm and put your system on "test.”
2. Find your main control panel , usually in the basement or in a closet. Open the panel (you will either need a key to unlock the box or a screwdriver to remove the screws if box is screwed shut).
3. Verify the new battery fits inside the control panel. Remove the red and black wires of the battery lead. It may need jiggled to loosen.
4. Find and unplug the transformer (the electrical plug - this will be plugged and possibly screwed into an outlet close to the panel).
5. Remove old battery and replace with new battery (may need to remove plastic coverings from new battery terminals).
6. Connect red wire to red terminal; black wire to black terminal.
7. Give the system a minute to recycle itself, then test it. Be sure you are able to arm and disarm the system. It may take several hours for the battery to fully charge. If you experience problems, contact us.
