Timeguard HF1 360° Flush Mount High Frequency (HF) Ceiling Presence Detector

Take control of your lighting with Timeguard’s 360° Flush Mount High Frequency Ceiling Presence Detector (HF1). By ensuring that lights are not left on in empty rooms, the HF sensor can help you cut down on both CO2 emissions and energy bills.

This high-tech lighting control solution makes a superb addition to offices, corridors, toilets, and more.
