Your home alarm system will make beeping sounds when the backup battery has been drained. This is usually the case whenever the panel is not receiving any power and cannot turn on. The beeping sound that the low battery alarm makes can become very annoying, but it can be disconnected by removing the drained battery from your home alarm system panel. Make sure to replace the drained battery with new ones to keep your home alarm system functioning properly.
Locate the alarm panel. It is usually located inside a closet in your house.
Open the alarm panel door by unlatching the clip on the center side of the door. Locate the drained battery. The battery will be located inside a small box on the alarm panel.
Pull the latches, which are located on both sides of the battery, down to release the battery from the panel. Remove the drained battery from the panel by pulling it out.
Replace the drained battery with a new battery from the manufacterer of your system as soon as possible to keep the system monitoring properly.
