Legrand North America has announced additional improvements to its portfolio of Wattstopper lighting controls. The Wattstopper Passive Infrared (PIR) wall switch occupancy sensor, the WS-301, now features Manual-ON control ensuring energy savings and code compliance. These sensors replace existing wall switches and are ideal for retrofit projects and other applications.

Installing WS-301 sensors into areas such as offices, conference rooms, and break rooms can generate energy savings up to 60 percent by turning lighting or fan loads on and off based on occupancy and ambient light level. The WS-301 also meets electrical safety {2011 NEC} and energy {California Title 24 (2016)/ASHRAE 90.1 (2013)/IECC (2015)} code requirements.

In addition to Manual-ON operation, other features and benefits include:

  • Neutral Sense technology offers an optional neutral connection ensuring out-of-the-box compatibility with existing wiring whether a neutral wire is available or not
  • Shallow back housing and flying leads for installation
  • Color options with matched lenses offering aesthetically pleasing low profile design
  • Vandal/tamper-resistant lens that provide coverage and durability

This upgrade is one of many enhancements being made to the company’s contractor-grade line of products.
