Occupancy Sensors 3-Way and 4-Way Switches
How do I install a motion a sensor to control lights? How to Wire 3-Way and 4-Way Occupancy Sensors to replace existing 3-way switches.
3-Way and 4-Way Occupancy Sensors for Indoor Motion Detector Applications
I have a three family home unit and in the common stairwell I have a 3-way switch on the first floor, a 4 way switch on the second floor and a 3 way switch on the 3rd floor which are all controlling the common stairway lighting. My question is how do I install a motion sensor so all the lights will go on when my tenants leave their apt at night? Can you please help?
This electrical wiring question came from: Craig, a Homeowner from Bristo, Connecticut.
Thanks for your electrical wiring question Craig.
How to Wire 3-Way and 4-Way Occupancy Sensors
- Hi Craig, you have asked a great question. Consider installing 3 -way occupancy sensor switches that have a wide angle coverage and variable time delays.
- These 3-way occupancy sensor switches may replace the existing 3-way switches.
- Install a 4-way occupancy sensor to replace the existing 4-way switch.
- The sensing pattern should be adjusted as wide as possible and the time delay should be adjusted to provide enough time to travel the full distance of the stairway.
- This modification should be tested to make sure that the occupancy sensor pattern will accurately detect movement on the stairs.
- The sensing may be inhibited due to stairway design or obstacles in the area.
- If the motion detection of movement on the stairway does not activate the occupancy sensors then another solution should be considered.
3-Way and 4-Way Occupancy Sensor Light Switches
I have found that Pass and Seymour have a multi-way Occupancy Sensor switch which you may consider for this application. Click here for the PDF file: Multi-Way Occupancy Switches
