Full-ON sensors activate the lights at full output. Partial-ON sensors activate the lights to a designated level such as 50%, and the occupant then uses a switch to bring the lights to full output.

Manual-ON sensors (also called vacancy sensors) require the occupant to turn the lights ON using a manual switch, which may be integral to the sensor (shown here is an example).

The majority of commercial building energy codes require manual- or partial-ON operation. Occupancy sensors may be specified as manual-, partial- or full-ON devices. It is based on an updated Education Express course that will be posted shortly TECHNOLGY Inputs This article provides information that can be used to select an appropriate sensor technology and product features based on a given application’s characteristics. They are also a common control feature in retrofit projects. According to the Lawrence Berkeley National Laboratory, occupancy-based strategies can produce average lighting energy savings of 24%.ĭue to their relative simplicity and high energy-savings potential, coupled with energy code mandates, these sensors are a staple in new construction.

The device may also turn the lights ON automatically upon detecting the presence of people, providing convenience and a potential security aid. Occupancy and vacancy sensors are devices that detect when a space is unoccupied and accordingly automatically turn OFF (or dim) the lights, thereby saving energy.
