Trouble Condition: "Lost"
SOLUTION TO WATER SENSOR - "LOST"

When Console displays “Lost”, the Sensor is no longer communicating with system.

Verify that Flood Sensor is no more than 30 feet from the following devices: Base, Console, Cellular Gateway, or Grid Extender. If device is more than 30 feet, move one of the controllers closer to location being monitored for temperature

If Flood Sensor is within 30 feet of a controller, then you may need a new battery (Se“Low Batt” article for details).

If Flood Sensor is within 30 feet of a controller and it is not the battery, you may need to delete then re-add the device (see setup steps). 

If you are still having difficulties, call Technical Support at 877-464-7437.
