To replace an existing WRZ Series Sensor, complete the following steps:


  1. Prepare the new WRZ Sensor by applying its mesh application overlay and setting its DIP switches.
    Important: The PAN OFFSET switch setting must be the same for all the ZFR1800 Series and WRZ devices on the same wireless mesh network.
  2. Turn off power to the WRZ Sensor that you wish to replace.
  3. Remove this WRZ Sensor.
  4. Install the two AA alkaline batteries (supplied) in the new WRZ Sensor.
  5. Move the POWER switch to the ON position.
  6. Mount the new WRZ Sensor.
  7. Wait 1 to 3 minutes for the sensor to find the network. Press and release the Occ button. Wait for the flash reply. Ensure that there is at least one flash. If not, see Troubleshooting for more information.
  8. Secure the sensor to its mounting base.
