Guangzhou Depu Intelligence is an authorized agent for Theben. The Presencelight 180 is a wall-mounted presence infrared sensor switch with a 360° circular detection area up to 8 meters in diameter (100㎡). The sensitive detection zone measures 7m × 3.5m and is highly responsive—even subtle movements like finger gestures, typing, or turning pages can trigger detection. It is designed for installation at heights between 1.7 to 2.2 meters, making it suitable for rooms, corridors, and similar spaces. Lighting is controlled by presence and brightness levels, compatible with fluorescent lamps (FL/PL/ESL), halogen/incandescent lights, and mixed light measurement for LEDs. Both fully automatic and semi-automatic operation modes are available. Features include adjustable brightness, configurable turn-on and turn-off delays, and a self-learning function. The brief presence feature reduces disconnect delay time during short occupancy periods. It includes one external input terminal for manual control convenience and pulse output functionality for integration with staircase timers. Sensitivity is adjustable,
and the detection area can be limited using cover clips. Detection coverage can be expanded via master/slave or master/master switching, supporting up to 10 sensors in parallel. Remote configuration via remote control is also an option.
