THEBEN THE PIRA T8-2 DE PIR Ceiling Motion Detector 360° 8m White

The THEBEN THE PIRA T8-2 DE is a ceiling-mounted passive infrared motion detector engineered for reliable presence detection in commercial and residential spaces. Unlike typical wall units, its round 360° detection area covers a full room circle from a single overhead point, making it ideal for corridors, offices, and open-plan areas where even coverage is essential.

Highlights

• 360° round detection area with up to 8 m diameter at a 2.5 m mounting height
• Flush ceiling mounting for discreet integration
• Switches resistive loads up to 2300 W and LED loads up to 600 W
• Adjustable time delay from 10 seconds to 30 minutes
• Adjustable brightness threshold from 5 to 2000 lux
• IP54 protection and UV-stabilised polycarbonate housing

In daily use

The PIRA T8-2 DE automatically controls lighting based on presence and ambient brightness. Once installed at the recommended height of 2.0 to 4.0 metres (optimum 2.5 metres), it reliably detects movement in the entire 360° field. A rotary knob for the time setting and a separate one for the brightness threshold allow quick adjustment without opening the unit. The device can handle almost any lighting load, including modern LED retrofits, and its 0.5 W standby consumption keeps energy costs low.
