  • Remove power from Water Sensor 7 for 1 minute, then power it up again.
  • Try factory resetting or excluding your Water Sensor 7.

      2. Press and hold the tamper switch for 5 seconds until the red LED blinks.
      3. Quickly release the tamper switch, and then immediately press and hold again. 
        • If successful, the LED will display a solid green LED.
