The WSX family of wall switch occupancy sensors gives simple and cost-effective solutions for commercial and residential lighting control applications. With your choice of passive infrared or dual technology with PIR plus patented Microphonics detection, the WSX family provides reliable sensing and dimming performance optimized for your space. These are easy to install and easy to program using the traditional push-button programming or the optional Sensor Switch VLP mobile application. So, check the detailed Sensor Switch programming instructions below.
Sensor Switch WSX Programming Instructions
You can change SensorSwitch operational settings with the help of a push-button sequence. Here, you can see the Sensor Switch programming instructions briefly.
- You have to press and hold the push button on your device until it flashes. When it flashes, you need to release the button.
- Now, select the appropriate function. You can see there a number of functions such as occupancy time delay, on mode, switch mode, photocell set-point, LED operation, restore factory defaults, minimum on time, manual on the grace period, dual technology, microphone grace period, predictive exit time and predictive grace time. Among all, you should press the suitable function that you want to change.
- When you selected the function, the flashes will begin. While flashing, you have to select the new setting as per your requirements
- While LED flashes back on the new setting, press and holds the button. And, you need to release the button when LED flashes rapidly.
- Now, reselect the function to save and exit.
- Once the new setting has been saved successfully, you can see the LED flashes confirmation twice. Then, consider that the programming has been done completely.

WSX Sensor Operation
WSX family sensors detect the changes in the passive infrared energy given off by occupants as they move within the field of view. For an Auto-On sensor, an internal relay switch will ON on the connected lighting load once the occupancy is detected. In a vacancy sensor, first pressed the push button of the vacancy sensor to initiate the lights ON. In a dual relay sensor, when occupancy is detected, it will close pole 1's relay automatically while still required pole 2's push-button to be pressed for closing pole 2's relay. These sensors have user-adjustable modes.
After the lights are turned on, an internal timer keeps them ON during brief periods of inactivity. When the time delay is expired, lights are turned off automatically. WSX sensors with PDT, first see motion using PIR and then engage Microphonics to listen for sounds that also determine continued occupancy. This technology adapts the sensor dynamically to its environment by filtering out constant background noise and detecting only noises typical of human activity.
Sensor Operational Settings
Occupancy time delay
The time sensor keeps lights ON after occupancy detection. It has time settings including 30 sec, 2.5 min, 5.0 min, 7.5 min, 10 min, 12.5 min, 15 min, 17.5 min, 20 min, and 30 min.
When occupancy is detected, automatic o turns lights ON. For manual on, you have to press the button to turn the lights on. Reduced turn-on directs the sensor to only turn on when there is a large motion like a person entering a room is detected. Weaker signals like reflections from glass will be ignored. If the lights are ON, the sensor returns to maximum sensitivity. It has setting modes of "Automatic on", "Manual on" and "Reduced turn on".
Default settings are:
- WSX (PDT) series: Automatic on
- Units with -SA, -VA, or -NL option: Manual on
- WSX (PDT) 2P series: Pole 1 Auto on and Pole 2 Manual on
- 2P units with -2SA, -2VA, or NL options: Both poles Manual On
Switch modes are used for dictating switch functionality.
Press the push button in override off mode (setting 1). It turns off and keeps the lights off until pressed again.
Disable the switch in setting 2. It prevents the button from lights turning on.
Setting 3: Predictive mode - The lights are turned off if you left the room. It has been done this by monitoring the empty space for a period after pressing the predictive grace time and then following a delay to allow exiting the room. When occupancy is detected the system will disable auto-on and hold the lights off until switching manually. If no occupancy is detected, then your sensor reverts to auto-on mode instantly.
If predictive mode with expiration is enabled, i.e., setting 4, the sensor will continue to monitor the space once the sensor has disabled auto-on. When there is no occupancy detected for a period that is equal to the occupancy time delay, your sensor will back to auto-on mode.
Photocell set point
The ambient light level at which the sensor prevents the lights from initially turning on. Once it is turned on, the lights will remain on until the occupancy time delay expires and turns them off.
It indicates the LED behaviour of your device. It has the settings including occupancy indication, relay indication, disabled, and override on. Remember that sensor changes to auto-on mode if you enable the photocell.
Along with the above, you can see more settings such as restore factory defaults, minimum on time, manual on grace period, dual technology (Microphonics), microphone grace period, predictive exit time, and predictive grace time. To get the reference for these settings, check to Sensor Switch operational manual.
Frequently Asked Questions
Does a motion sensor switch need a neutral?
To power the motion sensor and solid-state timer, neutral is necessary. Motion sensor doesn't work without at least one neutral and one hot. Any neutral in the house will suits since all neutrals are joined in the breaker box to the same terminal block.
What is an occupancy sensor switch?
An occupancy sensor is defined as an indoor motion detecting device. It detects the presence of a person to control lights or temperature or ventilation systems automatically. These occupancy sensors work by using infrared, ultrasonic, microwave technologies, and so on.
How do you wire a occupancy sensor switch?
Each occupancy sensor switch has two wires, one black and one red and one ground, i.e., green. You have to connect the black wire to line voltage from the panel and other should be connected to the light. Each black wire can be a line or load. Red should be the load wire.
