Malfunction indicates that this sensor is unable to send signals to your security panel and may not trigger an alarm or signal for help in an emergency.
If there was a previous report of a low battery for the sensor, it is likely the batteries need to be replaced. Click the option below to get further instructions on how to do this.
If there was not a low battery report, or this is an intermittent issue we recommend taking a look at the panel location. If the panel is within 5 feet of any large metal or electronic object the problem may be caused by interference. We recommend moving the panel at least 5 feet away from anything that could cause interference; items such as TVs, refrigerators, routers, and printers.
