Item no.:1030201

The PIRA T8 2 DE is a versatile PIR motion and presence detector for recessed ceiling installation indoors. With a 360° detection area up to Ø 8 m (50 m²) at 2.5 m mounting height, it provides reliable control for both lighting and HVAC systems.

It features 1 channel light (relay 230 V) and 1 potential-free presence channel, making it ideal for energy-efficient automation. The detector supports motion and brightness-dependent control, with adjustable brightness threshold (5–1000 lx) and switch-off delays for both light (5 s–15 min) and presence (10 s–120 min).

With factory presets for immediate operation, low <0.6 W power consumption, and compatibility with multiple lamp types including LEDs up to 200 W, the PIRA T8 2 DE ensures dependable performance in offices, meeting rooms, and indoor commercial spaces.
