Changing your security system battery, an important part of maintaining your alarm system, takes about 5 minutes and can be accomplished by following our easy instructions.

General Battery Information:

  • Your security system is equipped with a control panel battery which is designed to supply power your security system in the event of an electrical outage.
  • The security system battery is located in the control panel, usually placed in the basement or utility closet
  • In the event of an outage, your battery should last (provide power to your system) for about 48 hours.
  • Overall, your security system requires very little maintenance; however, your control panel battery may need to be changed every few years.
  • You will know to change your security system battery if If your keypad indicates "trouble" or "low battery."

How to Change The Battery

Step 1: Open the Control Panel Box

Open the control panel box, either by removing the screws on the side of the cover or with the control panel key. Note: The photo here does not show all of the internal components and wiring. Your control panel may also look different from this photo.

To change your system battery:

Step 2: Disconnect The Old Battery

  • Pull the black wire's connector from the negative (-) battery terminal. This may require pliers with electricity insulated handles. The connector may need to be wiggled slightly for it to loosen and become disconnected
  • Pull the RED wire's connector from the positive (+) battery terminal. This may require pliers with electricity insulated handles. The connector may need to be wiggled slightly for it to loosen and become disconnected.
  • Remove the old battery from the control panel box. WARNING: Do not touch any metal objects to the terminals on the battery or to the open-end of the black and red wire connectors.

Place the New Battery Inside the Control Panel Box

  • If the replacement battery has plastic terminal protectors, remove them before connecting the wires to the battery.
  • Connect the RED wire to the RED terminal of the new battery by pushing the connector firmly onto the terminal. If you do not see a RED colored terminal, look closely at the top of the battery for a positive (+) terminal.
  • Connect the BLACK wire to the BLACK terminal of the new battery by pushing the connector firmly onto the terminal. If you do not see a BLACK colored terminal, look closely at the top of the battery for a negative sign (-) next to the terminal and connect the BLACK wire to the negative (-) terminal.
