WattStopper PW-301-W – Frequently Asked Questions

1) Will the WattStopper PW-301-W occupancy sensor work on a 277V lighting circuit?
The PW-301-W wall switch occupancy sensor runs on 120, 240, or 277 VAC, so the same part covers a 277V ballast circuit in a commercial building and a 120V branch circuit in a residential or office space. That is one part number to stock across mixed-voltage buildings instead of a voltage-specific SKU per panel.
2) Does the PW-301-W wall sensor need a neutral wire in the switch box?
Neutral is optional on the PW-301-W. It uses a break-off tab so the sensor can be wired with or without a neutral connection, which matters in older boxes where only the switch leg and hot were pulled. Confirm what is in the box before you cut the tab, since the tab does not go back on.
3) Can I use two occupancy sensors to control the same lights from both ends of a corridor?
The PW-301-W supports multi-way control from up to four locations, so a corridor, classroom, or conference room with more than one entry can be switched and sensed from any of those points on one lighting load. That is what you want in a space where people enter from opposite ends; a single-location sensor leaves one entrance dark until someone walks into the pattern.
4) Will the PW-301-W occupancy sensor fit a standard single-gang switch box?
The sensor measures 4.8 x 2.0 x 2.99 inches and mounts in place of a standard wall switch, so it lands in a normal single-gang opening. The 2.99 inch figure is the depth behind the plate, which is the number to check against a shallow or crowded box before you order a full floor of them.
5) Do the lights come on by themselves with the WattStopper PW-301-W, or do I have to hit the switch?
Manual-ON is the default. Someone entering the room presses the sensor to turn the lights on, and the sensor turns them off after the space is vacant. That saves more energy than an auto-on sensor because a room crossed through briefly never lights up, and it is the behavior many energy codes ask for in private offices and similar spaces. If your tenants expect lights to come up on their own, this is the wrong choice.
6) Is a PIR wall switch sensor the right type for a restroom with stalls or an L-shaped room?
PIR is line-of-sight. The PW-301-W detects motion within its coverage pattern from the switch location, so it works well in open offices, private offices, retail floors, and classrooms where the occupant is visible from the door. Partitions, stall walls, or an L-shaped layout block the pattern and lights will drop on an occupied space. In those rooms use a dual-technology or ultrasonic sensor, or a ceiling-mounted unit that sees the whole floor plate.
7) What exact WattStopper part number do I order for the white manual-on PIR wall switch sensor?
PW-301-W is the part number. The PW-301 is the wall switch PIR sensor family and the W suffix is the white finish. Quote and order it as WattStopper PW-301-W.
8) Can I use the PW-301-W in a healthcare or school retrofit where I am standardizing sensors across the facility?
It is built for that kind of rollout. The sensor is specified for commercial offices, retail, educational and healthcare facilities, hospitality, multi-unit residential, and industrial buildings, and because it accepts 120, 240, or 277 VAC it covers every lighting voltage likely to be in one of those buildings. One part number, one white finish, one install method across the whole facility.
9) Will the white WattStopper sensor match the switches and plates already in my building?
White, with a color-matched white lens in a low profile face, so it sits with standard white devices and white cover plates across the rest of a floor. Property managers replacing switches a few at a time get a consistent look without repainting or swapping every plate on the wall.
