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, the panic pendant will need to be replaced.
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, printers.
If the malfunction persists, we recommend contacting Customer Support to help resolve the issue.
