Trouble Condition: Sensor Not Found
SOLUTION TO TROUBLE CONDITION - SENSOR NOT FOUND
If your system cannot detect a Sensor, the Console may display: SENSOR OUT OF RANGE. 
 
If this occurs, follow the steps below:
1.  Isolate Sensor: Remove Sensor from Bracket and set-up a different Sensor to the same Bracket. If additional Sensors do not work, proceed to Step 2
2.  Add a Grid Controller: If Sensor cannot be set-up or becomes “Lost,” your home may need additional Grid Controllers such as a Console, Grid Extender, or Cellular Gateway to expand wireless coverage
3.  Remove battery for 1 minute and replace. Then re-add Sensor
4.  Replace battery
5.  Take Sensor out of room and try again.  If this does not work, try another sensor in that bracket. If it still doesn’t work, call Technical Support at 877-464-7437
