Reliable PIR Control for Energy-Efficient Lighting
PIR detectors sense changes in infrared energy caused by people moving through their detection area. The Finder 18.51.8.230.0300 uses this technology to switch lighting automatically, providing convenient hands-free control while helping reduce energy consumption in areas that are not continuously occupied.
The integrated light sensor allows the detector to consider the available ambient illumination before switching the connected lighting. Combined with adjustable timing, this makes the Finder 18.51 suitable for a broad range of commercial and industrial spaces where reliable occupancy-responsive lighting is required.
Typical Applications
- Office and commercial building lighting.
- Corridors, hallways and communal areas.
- Stairways and circulation spaces.
- Schools and public buildings.
- Hotels and hospitality premises.
- Industrial and commercial facilities.
