Select Your Panel That Needs a Replacement Battery

Before replacing your battery, it's important you know about two essential components of your alarm system.


    • A large plug located in an electrical outlet, often secured with a screw to keep it from falling out, is the main source of power for your alarm system.

    • As long as there is power in your home, your system should always have power.

    • If the transformer stops supplying power, then the system will keep running by the system’s backup battery.

Backup Battery

    • The backup battery will keep the system running for a period of time in the event of a power outage. This period of time depends on the age of the battery and the number of devices it has to support during the outage.

    • The backup battery is located either inside the keypad (where the codes are typed in) or in a separate panel box often located in a closet. The location of the battery depends on the system type.

    • These backup batteries are rechargeable. Once power is restored, the battery will recharge on its own.

Before replacing your panel battery, we advise giving the backup battery 24 hours to fully recharge. If your system is still reporting a panel low battery after 24 hours, at that time we recommend a replacement. If you need to order a replacement battery, please text a Support Representative any time at 469.513.8685.
