NOTE: When performing firmware updates, ensure your mobile device is not interrupted by other apps or processes. An interruption
during an update could lead to an unrecoverable sensor failure. It is highly recommended to place your mobile device in airplane
mode (with only Bluetooth enabled) to reduce risk of an interruption.
The Update Firmware option is also located within the Sensor Options screen. When you select this option, the screen displays the
version of firmware within the specific sensor, and the version of firmware that is included with the app. If a newer version is available
and you want to update the sensor, tap Start Update. A progress screen will show the progress of the update. Once complete, the
display indicates completion and you can return to the Sensor Options screen.
NOTE: While updating the unit, an Abort button allows you to stop the update. Please note that use of this button during an update
could result in an unrecoverable sensor failure.
NOTE: The app contains the latest versions of the firmware for each model sensor. If a new version of firmware is released, a new
version of the app will be made available for download, containing the updated firmware.
Lights will not go to High Mode:
• Check all wire connections and verify the load and the ground wires are tightly secured.
• Make sure that the sensor is not obstructed.
• Check light level parameter, to find out the amount of light that the sensor is detecting. Cover the sensor lens to simulate darkness
in the room. If the lights come ON, the setpoint needs to be adjusted. If set for minimum, more than 1 fc at the sensor of ambient
light will cause the lights to be held OFF. See the new settings section for instructions.
• If lights still do not turn ON, call 800.879.8585 for technical support.
Lights will not go into Low Mode:
• The time delay can be set from a minimum of 30 seconds to a maximum of 30 minutes. Ensure that the time delay is set to the
desired delay and that there is no movement within the sensor's view for that time period.
• T o quickly test the unit operation, enable test mode and move out of the sensor's view. Lights should fade to low mode after 5 seconds.
• If lights still do not fade to Low Mode, call 800.879.8585 for technical support
Lights will not turn OFF:
• Cut Off time may be set to "Disable."
• Ensure that the Cut Off is set to the desired time and that there is no movement within the sensor's view for that time period when
the lights are in Low Mode.
• To quickly test the unit operation, enable test mode and move out of the sensor's view. Lights should fade to low mode after 5
seconds and then turn OFF (if cut off is enabled) after 10 sec.
• If lights still do not turn OFF, call 800.879.8585 for technical support.
