Flood + Freeze Sensor Loss of Supervision

Understanding Flood + Freeze Issues

It is important to regularly test and maintain all system sensors. A low battery or abnormal damage to the sensor can cause irregular activity, including loss of supervision. Loss of supervision is an automatic diagnostic the system uses to verify that sensors are wireless communicating properly. Other contributing factors that can cause loss of supervision are distance to the panel, large mirrors, large fish tanks, large metal objects, or concrete/mortar barriers and objects.

Step by Step Instructions

When your sensors are experiencing a LOSS of SUPERVISION we need to identify if it is being caused by:

  1. The distance of the sensor from the panel and/or interference
  2. A low battery or
  3. A bad sensor


To test if your sensor is too far from the panel:

  • Change the location of the panel to be closer to the malfunctioning sensor (within 10-20 feet). This is a temporary troubleshooting step. You do not have to keep your panel next to the sensor
  • Test the sensor to reconnect it to the panel
  • Wait 48 hours to see if the issue persists

Deleting the sensor and re-adding it back:

  • If your issues persist, delete the sensor from the system
  • Re-add it back to the system. For a door use this link, for a window use this link. 
  • If the sensor will not clear or continues the Loss of Supervision, follow the next steps. 

If deleting and adding back the sensor does not fix your issue

  • Try replacing the battery. When you take out the battery, please wait 30-40 seconds before inserting the new batteries. 
  • Test the sensor to reconnect it to the panel
  • Wait 48 hours to see if the issue persists

  • My flood sensor keeps losing connection with the panel. I have it one floor below in our basement space near the boiler. Is there a distance limit on the panels? Technically, the flood sensor is almost directly below where we have the panel, in a semi split ranch. It didn't communicate at all when it was right next to the boiler, so I moved it about 10 feet from the boiler and closer to the door and it communicates intermittently.  Our window sensors are further away than the flood sensor. Is it possible it's defective? We've only had it less than a week. 

    • Victoria Parkin The effective range of the panel is approximately 150-200 ft, depending on the layout of your home. Large metal appliances, such as a boiler, can cause connection issues between the sensor and the control panel. Please give us a call at 855-268-3669 to troubleshoot that sensor.
