What kind of battery does the 5811 wireless sensor use for power?Last Updated: 11/21/2013 |

Replacing a battery... Open the 5811 back plate by using a flathead screwdriver to turn open the notch. Pop out the old battery and replace with a new CR2032 lithium cell battery. Then snap on the back plate. The low battery message on your alarm keypad will be cleared away as soon as the control panel recognizes that a new battery has been installed in the 5811 wireless door / window sensor.
