A malfunction (or sensor offline) occurs when the Control Panel has not received a signal from the Door and Window Sensor in the last 24 hours. If your Door and Window Sensor reports offline or malfunction, check for a low battery signal in the history. If it has reported a low battery recently, change the batteries. If there is no low battery, or if replacing the batteries does not clear the status, please contact Customer Support for further troubleshooting assistance.
