The Sensor Configuration app allows bi-directional communication
between the FSP-321 and the mobile app. Simple menu screens
let you see the current status of the sensor and make changes.
It can change FSP-321 sensor parameters such as high/low
mode, sensitivity, time delay, cut off and more. With the Sensor
Configuration app you can also establish and store FSP-321
parameter profiles and enable continuous dimming.
The Sensor Configuration mobile app has the ability to detect
multiple sensors based on signal strength or distance.Every time
the commissioning tool establishes communication with the FSP-
321, the controlled load will flash, providing a visual indication of
which FSP-321 you are configuring.
For details on the features and operation, download the Config
App User Guide from the wattstopper web site at :

NOTE: The Bluetooth low energy technology radio stops
broadcasting after 7 days of being powered on if no
password is set for the device. Cycling the power turns
the Bluetooth radio back on.
1. The first time the sensor is installed and powered, there will be 50 seconds of warm-up. The load will turn OFF after the warm-up
time if no motion is detected. To test functionality further, proceed to steps below
2. Log in to the Sensor Config App, then tap Device Discovery. The Devices screen opens and displays a list of sensors along with
their signal strength.
3. Tap a sensor. The loads connected to that sensor will flash ON and OFF, to give a visual indication of which sensor you are
communicating with. After a few seconds, the Device Security screen opens.
4. Turn the Select Jobsite switch Off.
This allows you to test the sensor
without having to store a password in
the sensor. Than tap Submit.
5. Tap the Controls option. The
parameters on this page are used for
testing the sensor. Additionally, the
current amount of light registered by
the light level sensor, as well as the
sensor's firmware version is displayed.
6. Tap Test Mode. This mode shortens
timeouts for High/Low and Cut Off,
to allow quick verification of settings.
You can set the length for test mode
(default is 3 minutes). Range: 1 to 5 minutes. Tap Start to enter test mode.
7. If you tap Dimmer Level, the screen shows the current dimming level (from 0V to 10V). You can temporarily change the dimming
level for testing purposes by dragging the slider or tapping the "+" or "–" buttons. The level will change to the specified amount for
several seconds, then revert to the previous amount.
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.
• 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
