Introducing the Knightsbridge OS0025W PIR
Flexible Installation, Energy-Saving Performance
Automatic lighting control provides the ultimate convenience while reducing energy waste in spaces where lights are frequently left on. The Knightsbridge OS0025W PIR sensor provides a practical solution with genuine installation flexibility. The adjustable settings allow fine-tuning for different spaces, while the parallel wiring capability means larger areas can be covered with multiple units working together.
NB: This is a PIR sensor, not an occupancy sensor.

Perfect for Energy-Saving Installations
This PIR sensor is ideal for locations where lights are frequently left on – corridors where people pass through but don’t return to switch off, stairwells serving multiple floors, storage areas where the light switch is inevitably forgotten, plant rooms and service areas with infrequent but necessary access, and commercial spaces where multiple users mean nobody takes responsibility for lights.
The energy savings add up quickly, particularly with commercial installations where lighting operates long hours. Automatic control means lights only run when actually needed, reducing electricity costs without requiring user behaviour changes.
