WattStopper CS-50-W – Frequently Asked Questions

1) Does the WattStopper CS-50-W need a neutral wire at the switch box?
No. The CS-50-W is a 2-wire sensor, so it wires in like a standard switch without a neutral. That makes it usable in older boxes where only the switch leg and line are present, which is often the deciding factor on a retrofit in an existing building.
2) Will a vacancy sensor like the CS-50-W turn the lights on by itself when someone walks in?
It won't. The CS-50-W is manual-on, automatic-off: someone has to press the switch to turn lights on, and the PIR sensor shuts them off after the space is vacant. That's the behavior code officials and energy programs usually mean when they call for a manual-on vacancy sensor rather than an occupancy sensor.
3) Is the WattStopper CS-50-W a PIR sensor or dual technology, and does that matter for my room?
It's passive infrared only. PIR needs line of sight to motion, so it works well in open private offices, small classrooms, and retail back rooms, and is a poor choice for restrooms with stalls, L-shaped rooms, or anywhere partitions block the view of the occupant. For those layouts, look at a dual-technology (PIR plus ultrasonic) wall switch sensor instead.
4) Can I adjust how long the lights stay on after the room empties?
Yes, the CS-50-W has an adjustable time delay, so shutoff timing can be set to suit the room. Short settings suit a restroom or storage closet; longer settings suit a private office or conference room where people sit still and PIR can lose them.
5) How do I confirm the sensor is actually seeing motion during commissioning?
The CS-50-W has an LED status indicator that flashes on detection, so a single tech can walk the room and verify coverage before closing out the job. It's also the first thing to check when a tenant reports lights dropping out: if the LED isn't picking up the occupant at the desk, the sensor placement or the time delay is the issue, not the fixture.
6) What part number do I order for the white WattStopper 2-wire vacancy sensor?
CS-50-W is the WattStopper part number for the white version of this 2-wire manual-on vacancy sensor. The -W suffix is the color. Quote it by that number when standardizing offices or dorm rooms across a property so every box gets the same device.
7) Will the CS-50-W match the other decorator switches and wall plates on my floor?
It's white, with the compact decorator-style body that sits behind a standard wall plate, so it lines up with white devices already on the wall. The sensor ships as the device itself, so budget a wall plate if the existing one isn't being reused.
8) How much room does the CS-50-W take up in the box?
The device is listed at 4.5 in deep, 3.0 in wide, and 2.74 in high, at 0.35 lb. Sensors are deeper than a toggle switch, so on a shallow old-work box with a full bundle of conductors behind it, check the remaining depth before you order a batch.
